by DeCandolle and in its decidedly urceolate almost globose rather 
than cylindric corolla; also in the fact that the corolla-lobes are more 
than half as long as the tube. S. parvifolia Planch., to judge from 
Nelson’s n. 1836, so identified at the Royal Gardens at Kew, has a 
much more slender corolla. S. angulata Planch. is described by Hems- 
ley, Biol. Cent.-Am. Bot. i. 185, as having flowers only one and one- 
half lines long and branches angled, while in the present species the 
branches are terete and even the branchlets are scarcely angled, the — 
flowers being furthermore fully 3 lines long. The genus, however, is 
much in need of a thorough revision. :

series by its conspicuous petiolar glands.
