A new shrubby species of Nasa Weigend ser. Carunculatae (Urb. & Gilg) Weigend (Loasaceae) from the Amotape-Huancabamba Zone

Tilo Henning Asunción Cano Maximilian Weigend

Nasa is the largest genera in the Loasaceae family and it is particularly speciose in the Amotape-Huancabamba Zone of northern Peru. Nasa ser. Carunculatae is a group of four species, three of them endemic to the Amotape- Huancabamba Zone. Species in this group are characterized by their shrubby habit, deciduous leaves, and typical tilt-revolving flowers with white to greenish petals. In this work, we describe a new species of Nasa ser. Carunculatae from the southern limit of Amotape-Huancabamba area, La Libertad, Peru. The species differs from others in having much smaller and notably narrower leaves. Unlike all the other species of ser. Carunculatae, the entire distal portion of the stem is densely glandular. It is apparently most closely related to Nasa carunculata, a species known from inter-Andean valleys of Ancash and Ayacucho.

Phylogenetic relationships and generic re‐arrangements in “South Andean Loasas” (Loasaceae)

Taxon (2017)

Rafael Acuña Stella Fließwasser Markus Ackermann Tilo Henning Federico Luebert

Abstract Loasaceae, a mostly American group, is one of the largest families of Cornales. In spite of considerable progress over the last 20 years, the relationships of some clades remain controversial, especially in the “South Andean Loasas” (SAL— Blumenbachia, Caiophora, Loasa, Scyphanthus ). The present study addresses the phylogenetic relationships in SAL employing four plastid markers ( rps16, trnL‐trnF, trnS‐trnG, matK ) and ITS and aims at resolving the systematics and evolution of the group. Sequences obtained from a total of 59 SAL species (ca. 70% of the total, representing all lineages in the group) and 25 outgroup taxa were analysed using maximum likelihood and Bayesian inference approaches. ML best and BI strict consensus trees showed no significant differences in their topologies. Our results confirm that two species of Loasa ser. Malesherbioideae are not part of the SAL clade, but should be included in Presliophytum, a result which is here formalized. Blumenbachia (including sect. Angulatae and sect. Gripidea ) is confirmed as a monophylum with high support. Loasa has to be redefined and restricted to a clade including only ser. Deserticolae, ser. Floribundae, ser. Loasa and ser. Macrospermae. Scyphanthus and Caiophora both are each monophyla and sister groups, but with two clades of Loasa as successive sister groups: ((( Caiophora+Scyphanthus )+ Loasa ser. Pinnatae )+( L . ser. Volubiles + L . ser. Acaules )) in a very well‐supported clade. Accordingly, Caiophora, Loasa ser. Pinnatae, L . ser. Volubiles , L. ser. Acaules and Scyphanthus could be included into a single genus, with Scyphanthus taking priority over Caiophora, creating a fairly heterogenous genus of ca. 52 species and requiring 50 new names. Alternatively, the clades Loasa ser. Pinnatae and L . ser. Volubiles + ser. Acaules can be removed into new segregate genera, which is here argued for and which requires the creation of only 16 new names. The new genus names and some of the new combinations are here formalized.

Revista Peruana de Biología (2006)

Maximilian Weigend Nicolas Dostert Tilo Henning Christof Schneider Eric F. Rodríguez Rodríguez

In the present paper, the valid names of 101 taxa of new species, new subspecies and new combinations of the genera Nasa and Aosa (Loasaceae: Cornales) are published. The invalid names of these taxa were originally published in various articles in the last ten years. This publication is carried out on the basis of the changes in the International Code of Botanical Nomenclature approved in the International Botanical Congress (IBC) in Viena, 2005. For each taxon the valid names, protologue citation and type are provided, in the case of the 41 new species and subspecies a latin diagnosis is included, as per requirement ot the Code. We additionally provide the citation for the original, invalid publication and corresponding illustration of the taxon. The taxon list here provided represents a complete list of all taxa currently known in the genus Nasa, including the species recently validated in TAXON.

A Revision of Nasa ser. Carunculatae (Loasaceae subfam. Loasoideae)

Systematic Botany (2003)

Maximilian Weigend Tilo Henning Christof Schneider

Abstract Nasa Weigend ser. Carunculatae (Urb. & Gilg) Weigend is revised, four species are recognized, and one, Nasa usquiliensis Weigend, T. Henning & C. Schneider described as new to science. The species of this group are restricted to steep scree slopes in Peru and southern Ecuador and have patchy distributions at elevations of 2200–3500 m. All species share shrubby habit with ligneous stems and deciduous foliage. These characters in combination with clawed, spreading petals and bicolored nectar scales are unique in Nasa. Branched root-tubers are reported from N. carunculata, which is the first report of tuberous storage roots in the genus. Species delimitation is primarily based on habit, trichome characters, flower size, petal color and shape, and the morphology of the floral scales.

Flowers anticipate revisits of pollinators by learning from previously experienced visitation intervals

Figshare (2019)

Moritz Mittelbach Sandro Kolbaia Maximilian Weigend Tilo Henning

Plants – and their pollinating counterparts – display complex and sophisticated mechanisms to achieve successful pollination. It probably was only a matter of time for proof of plant intelligence in the context of floral ecology to surface, i.e. the memorization of previous events and a corresponding adjustment of flower behavior. In a recent study we presented a large experimental dataset on the evolution of stamen movement patterns observed in Loasaceae and the apparent role of plant behavior in the diversification of this plant group. The findings at species level suggest that individual plants may be able to adjust the timing of their pollen presentation to the actual pollination scenario they experience. Here we provide first evidence for a pre-emptive stamen presentation in Nasa poissoniana (Loasaceae), based on previously experienced pollinator visitation intervals. Using the unique ability of fast and precise stamen movements in response to a previous stimulus of the nectar scales, the plants should be able to reduce pollen loss and increase outbreeding success via optimizing the timing of male function. We discuss this behavior and its implications in the light of the recent literature and propose questions for future investigations.

A case of behavioural diversification in male floral function – the evolution of thigmonastic pollen presentation

Scientific Reports (2018)

Tilo Henning Moritz Mittelbach Sascha A. Ismail Rafael Acuña-Castillo Maximilian Weigend

Obvious movements of plant organs have fascinated scientists for a long time. They have been studied extensively, but few behavioural studies to date have dealt with them, and hardly anything is known about their evolution. Here, we present a large experimental dataset on the stamen movement patterns found in the Loasaceae subfam. Loasoideae (Cornales). An evolutionary transition from autonomous-only to a combination of autonomous and thigmonastic stamen movement with increased complexity was experimentally demonstrated. We compare the stamen movement patterns with extensive pollinator observations and discuss it in the context of male mating behavior. Thigmonastic pollen presentation via stamen movements appears to be a crucial component of floral adaptation to pollinator behaviour, evolving in concert with complex adjustments of flower signal, reward and morphology. We hypothesize that rapid adjustments of pollen presentation timing may play a significant role in the diversification of this plant group, representing a striking example for the evolutionary significance of plant behaviour.

Dynamic diversification history with rate upshifts in Holarctic bell‐flowers (Campanula and allies)

Cladistics (2017)

Katy E. Jones Nadja Korotkova Jörn Petersen Tilo Henning Thomas Borsch

Campanula s.l. is one of the most speciose flowering plant lineages of the Holarctic (ca. 600 species). In the present study we sequenced three regions of the plastid genome (petD, rpl16 and trnK/matK) across a broad sample of Campanula s.l., which markedly improved phylogenetic resolution and statistical support compared to previous studies. Based on this robust phylogenetic hypothesis we estimated divergence times using BEAST, diversification rate shifts using Bayesian Analysis of Macroevolutionary Mixture (BAMM) and TreePar, and ancestral ranges using Biogeography with Bayesian (and likelihood) Evolutionary Analyses in R. Campanula s.l. is estimated to have originated during the Early Eocene but the major diversification events occurred between the Late Oligocene and Middle Miocene. Two upward diversification rate shifts were revealed by BAMM, specific to the crown nodes of two Campanula clades: CAM17, a mostly South European-SW Asian lineage originating during the Middle Miocene and containing nearly half of all known Campanula species; and CAM15B, a SW Asian-Sino-Himalayan lineage of nine species originating in the early Pleistocene. The dynamic diversification history of Campanula and the inferred rate shifts are discussed in a geo-historical context.

When the absence of evidence is not the evidence of absence: Nasa (Loasaceae) rediscoveries from Peru and Ecuador, and the contribution of community science networks

PhytoKeys (2023)

Tilo Henning Rafael Acuña Castillo Xavier Cornejo Paúl Gonzáles Edgar Segovia

Documentation of plant taxa has long been subject to the temporal and spatial selectivity of professional research expeditions, especially in tropical regions. Therefore, rare and/or narrowly endemic species are sometimes known only from very few and very old herbarium specimens. However, these taxa are very important from a conservation perspective. The lack of observations of living plants and confirmation of the actual occurrence of taxa hinders the planning and implementation of effective conservation measures. Community science networks have recently made tremendous contributions to documenting biodiversity in many regions across the globe. The rediscovery of six species of Nasa (Loasaceae) from Peru and Ecuador primarily via the platform iNaturalist, is reported.
