Rubus

Rubus is a large and diverse genus of flowering plants in the rose family, Rosaceae, subfamily Rosoideae, with 250–700 species. Raspberries, blackberries, and dewberries are common, widely distributed members of the genus. Most of these plants have woody stems with prickles like roses; spines, bristles, and gland-tipped hairs are also common in the genus. The Rubus fruit, sometimes called a bramble fruit, is an aggregate of drupelets. The term 'cane fruit' (or 'cane-fruit'), or 'cane berry' (or 'caneberry'), applies to any Rubus species or hybrid which is commonly grown with supports such as wires or canes, including raspberries, blackberries, and hybrids such as loganberry, boysenberry, marionberry and tayberry. The stems of such plants are also referred to as canes. Most species are hermaphrodites, Rubus chamaemorus being an exception. The blackberries, as well as various other Rubus species with mounding or rambling growth habits, are often called brambles. However, this name is not used for those like the raspberry that grow as upright canes, or for trailing or prostrate species, such as most dewberries, or various low-growing boreal, arctic, or alpine species. The generic name means blackberry in Latin and was derived from the word ruber, meaning 'red'. The scientific study of brambles is known as 'batology'. Examples of the hundreds of species of Rubus include: The British National Collection of Rubus is held by Barry Clark at Houghton, Hampshire. His collection stands at over 200 species and, although not within the scope of the National Collection, he also grows many cultivars.
