night to three weeks before L. rotundifolius, and is a 
much smaller plant, does not grow above three feet high, 
and can nearly or quite support itself without a stick. Its 
geographical area is very restricted, being confined to the 
neighbourhood of Constantinople, and the opposite coast of 
Bithynia, where it grows amongst bushes. According to 
Boissier L. rotwndifolius is also a ‘native of Byzantium, and 
extends thence to mid-Russia, Armenia and Persia; but Mr. 
Baker considers this an error, and that L. rotundifolius will 
prove to be restricted to the Caucasus and Crimea. 
Plants of L. undulatus were received at the Royal 
Gardens, Kew, from those of Glasnevin in 1895, and from 
one of these the accompanying drawing was made in May, 
1896. 
Deser.—Quite glabrous. Stem two to three feet high, 
slender, scandent, narrowly winged. Stipules semisagittate, 
one-half to two-thirds of an inch long, bipartite, with a 
rounded sinus; segments divaricate, upper short, subu- 
late, erect, lower much longer, subulate-lanceolate, erect or 
deflexed, Leaves with two opposite leaflets, a rather stout 
compressed petiole, about an inch long, terminated by a very 
slender rigid stipes, which bears a trifid terminal cirrhus ; 
leaflets two to three inches long, sessile, elliptic or ovate, 
acute or mucronate, 5—7-nerved, dark green above, pale 
beneath, margins undulate, nerves very slender and 
anastomosing above, prominent asis the midrib beneath. 
Peduncle much longer than the leaves, erect, slender, 
loosely five- to seven-flowered. Flowers about half an inch 
broad, bright rose-purple, fading to violet, inodorous. 
Calyz-tube campanulate, lobes lanceolate, or deltoidly 
Janceolate. Standard orbicular, not callous at the base. 
Wing-petals oblong, tips and basal auricle rounded. Keel- 
petals semicircular, hardly auricled. Ovary pubescent, 
style short, stigma trulliform. Pod two to three inches 
long, linear, flat, glabrous, gradually narrowed from the | 
middle to the base, tip incurved, upper suture keeled.
