white hairs ; tube very short, apparently about 1 J lin. deep and \ in. 

 in diam. ; lobes very spreading, about f in. long and J lin. broad, 

 narrowly oblong or somewhat spathulate-oblong, acute, reflexed along 

 the margins. Outer corona cupular, circular in outline, truncate, 

 glabrous ; inuer coronal-lobes 1 lin. long, incumbent on the backs of 

 the anthers, rhomboid, acute, dorsally and rather broadly adnate to the 

 outer corona almost up to its margin.

Imperfectly known species, 



19. C. Ango, N. E Br. in Gard, Chron. 1892, xii. 369. Stems 

 a span high, erect, branched, 3-4-angled, glabrous; angles stoutly 

 toothed ; teeth acute, usually ascending. Flowers arising from the 

 upper part of the branches, shortly pedicellate. Sepals oblong-lance- 

 olate, acute, glabrous. Corolla scarcely 1 in. in diam., deeply 5-lobed ; 

 lobes ovate-oblong, acute, green on the back blackish-purple within. —

1 have not seen this plant and I am informed that there is no specimen of it in 

 Rich ird's herbarium. I doubt if Beccari's plant is the same as that collected by 

 Quartin Dillon. There is a specimen named S. Ango, in the Museum d'Histoire 

 Naturelle, Paris, collected at Dschadscha (Jaja), 4000 ft. elevation, by Schimper 

 (1289); of this I have only seen a drawing, which appears to me to represent the 

 plant I have described as C. Sprengeri. Possibly C. Sprengeri may prove to be 

 synonymous with C. Ango, but as many species of this group are much alike in 

 general appearance, and this native name Ango is aj)plied to several distinct species, 

 it appears to me best to consider them as distinct. 



20. C. decaisneana, N. E. Br. in Gard. Chron. 1892, xii. 369. 

 Stems erect, cylindric, 4-ribbed rather than tetragonal (elongate, weak, 

 4-angled, ex Decaisne), whitish-green speckled with red ; ribs rounded, 

 very prominent (angles acutely toothed, ex Decais7ie). Flowers small 

 (few, congested at the apex of the stems, ex Decaisne); lobes elongated- 

 triangular (ovate, ex Decaisne)^ spreading like a star, reddish-brown, 

 powdered with very minute whitish papillte. — Boucerosia decaisneanM,

I have not seen this plant, nor Lemaire's figure of it. 



21. C. adscendens, R. Br. (an Indian species), is quoted by 

 Terracciano in Ann. Istit. 13ot. Roma, 1894, v. 105, as growing on 

 Mandola Island in the Red Sea, but no description is given of the 

 plant, and I altogether doubt the identification.
