Spec. Char., S[C. A low shrub, with trifoliolate glabrous leaves, and roundish serrated leaflets. Flow- 

 ers in pairs, almost sessile, and disposed in a leafless raceme. Calyx villous, and one half shorter 

 than the corolla. A native of mountains in Valencia and Aragon, and of the Pyrenees in the part 

 contiguous to France. (Dec. Prod., ii. p. 164.) Introduced in 1816. It grows to the height of from 

 1 ft to 2 ft., and produces its yellow flowers from May to July. 



App. i. Other siiffmticose Species qfOnbnis. 



O. peduncularis Lindl. (But. Reg., t. 1446., and our Jig. 301.) is a 

 small shrub, not more than a foot high, introduced in 1829, from 

 Teneriffe, with fragrant white and rose-coloured flowers. It is 

 usually kept in a frame. It would do, with a little protection, for 

 rockwork. It is in Messrs. Young and Penny's collection. 



O. crispa L., O. hispdnica, O. vagfnalis L., O. arachnb'idea La- 

 peyr., O. longifblia Willd., O. falcata Willd.,0. ramosissima Desf., 

 O. tridentuta L., O. angustifolia Lam., and O. fce'tida Schousb., are 

 other species of Onbnis varying in height from 1ft. to 3 ft, and 

 usually kept in frames or cold-pits ; but which, if protected in severe 

 weather, would be very ornamental for rockwork. Descriptions of 

 them will be found in our Hortus Britannicus, and in Don's Miller. 



Other species of Onbnis marked in catalogues as herbaceous, are 

 nearly as suffruticose as those last mentioned; and, where the object is 

 to extend a collection, there are several that may be introduced in 

 the arboretum. Indeed it may be safely assumed, that, where several 

 species of a genus are ligneous or suffruticose, all the species of that 

 genus are more or less so, and may, by culture, be prevented from 

 dying down to the ground during winter; provided that genus has 

 been formed on natural principles.

Derivation. From a, privative, and morphe, form ; in reference to the deformity of the corolla, from 

 the want of the wings and keel. 



Description, Large deciduous shrubs, natives of North America. Leaves 

 impari-pinnate, having many pairs of leaflets that have transparent dots in 

 their disks, and, usually, minute stipules at their base. The leaves have de- 

 ciduous stipules. The flowers are disposed in lengthened spiked racemes, 

 usually grouped at the tips of the branches; of a blue- violet colour. {Dec.
