REVISION OF THE NATURAL ORDER HEDERACES. 293 
Wall. Cat. n. 49124; G. Don, Gen. Syst. iii. p. 394. Hedera 
Wallichiana, Steudl. Nom. Bot.—Nepal (Wallich ! n. 49124) ; Khasia 
Mountains, 2000—4000 feet high (Hooker fil. et Thomson !) 
Segments of leaves ovate at base; minutely dentate, or almost quite 
entire at the edge. Peduncles unarmed.

Ham. in D. Don, Fl. Nepal. p. 185; De Cand. Prodr. iv. p. 264. 
—Nepal (Hamilton! in Mus. Brit.). 
Segments of the leaves acute at base, and coarsely serrated at the 
edge; umbels on stiff peduncles 2-3 inches long. 
Obs.—The leaves of the last three species seem, at first sight, com- 
pound, but on closer inspection it will be found that there is no articu- 
lation at the base of the apparent leaflets, but that the top of the pe- 
tiole is expanded, then suddenly contracted, and again expanded into 
leaflet-like segments. In B. confluens the same structure is repeated 
` ona much larger scale. I took some pains to investigate this struc- 
ture, as Brassaiopsis seemed to be the only genus of the Order in 
which simple and compound leaves occurred together.
