was based, with certain species of Baissea^ and consequently transfierred it to this genus. 

 In this I concur entirely with him. He maintains the other species of Zygodia, 

 of which he saw only Z. urceolata, in the genus Zygodiai but, even with this 

 emendation the two genera iire not perfectly homogeneous. I have indicated this 

 by dividing each of theoi into two sections, viz., JEubaissea and Ghierkea, and Euzy- 

 godia and Sualla. They are in so far parallel sections, hs Euhaissea and Sualla 

 possess supra-staminal scales, though of a somewhat different disposition, whilst 

 Guerkea and Euzygodia iiave none. I do not consider myself justified to go 

 beyond this, as we know these plants very imperfectly, each of the species of 

 Zygodia, tor instance, being known only from a single collection and mostly a single 

 8i)ecimen. 



*Eu-Baissea. — Corolla- tube with fleshy calli or scales just above the insertion of 

 »the stamens. 



Panicle glabrous or only the peduncle, the lower part of 



the 1 hachis and the bracts more or less pubescent. 



Calyx 2 lin. long ; leaves with 11-12 secondary 



nerves on each side, raised on both surfaces . 1. B. calophylla. 

 Calyx |-1 lin. long; leaves with 4-9 secondary 

 nerves on each side, raised below and channelled 

 above. 

 Corolla-tube 1^-lf lin. long; lobes up to 8 lin. 

 long ; secondary nerves 7-9 ou each side, 

 equally conspicuous ..... 

 Corolla-tube 3^ lin. long; lobes 5 lin. long; 

 secondary nerves 4-6 on each side, the lower 

 very conspicuous, the upper faint 

 Panicle pubescent, minutely tomentose or finely fm*- 

 faraceouB all over. 

 Intra-calycuiar giamls 0; corolla-lobes 2-6 (rarely 

 only 1^) times longer than the tube; stigmatic 

 apiculus short. 

 Leaves small (^-1 in. long, 3-5^ lin. broad) ; 

 corolla-tube 1^ lin. long; lobes up to 10 lin. 



long 4:. B. Wulfhorstii. 



Leaves larger and corolla-lobes shorter than in 

 the preceding species. 

 Corolla-tube loosely villous in the throat ; ovary 

 hairy. 

 Corolla-lobes 5-7^ lin. long 

 Corolla-iobes not exceeding 4 lin. in length. 

 Leaves elliptic-oblong, rounded at the base; 

 infiorescence moderately lax with fili- 

 form branchiets ... 

 Leaves more or less lanceolate to oblong, 

 acute or cimeate at the base; in- 

 florescence very loose with capillary 

 branchiets ..... 

 Corolla-tube glabrous in the threat; ovary gla- 

 brous 7. -B. Thollonii, 



Intra-caiycuiar glands 5 (very rarefy 3) ; corolla- 

 lobes usually as long as or slightly longer than 

 the tube (3 times as long in B. major and 

 B. tenuiloha) ; stigmatic apiculus usually fine, 

 subulate. 

 Corolla-lobes 3 times as long as the tube.
