which has since been shown coincident with Pentas. In any case 

 VignaiLdia lutea Schweinf. must be regarded as a nomcn nudum in 

 the absence of any description. To avoid further confusion in the 

 matter, I propose a new name for the genus. This will include 

 not only M. luteola Del, but two other species with capsular 

 fruits previously described under Mussanda, as referred to below, 

 and also a fourth species recently collected by Gossweiler and 

 described here for the first time. 



From close apparent resemblance to Micsscenda I propose the 

 generic name 



Pseudomusssenda, 



RuBiACEARUM tribu CoNDAMiNEARUM (§ Pinhieyearum) novum 

 genus. 



Calycis tubus turbinatus v. sub-oblongus ; Hmbus 5-merus, 

 quorum partum 4 angustissimi pro rata elongati, unus saspius in 

 laminam petaloideam productus. Corollse tubus elongatus, gracilis 

 intus in fauce necnon in ore villosissimus, lobi patuli lati, valvati. 

 Stamina 5, antheris in corollae fauce villoso subsessilibus. Ovarium 

 2-loculare ; stylus gracilis ramis 2 linearibus ; ovula numerosa. 

 Capsula saepius oblonga, 2-locularis, loculicide 2-valvis.

This is a more delicate plant generally than the previous 

 species. The branches are very straight, slender, and early 

 invested with a greyish bark. The youngest are minutely 

 pubescent, rather short, and bear the few-flowered corymbs 

 terminally. The leaves are very thin, lanceolate to elliptical, 

 acuminate with sub-acute apex, ± 7 cm. x 3 cm., and gradually 

 narrowed at the base into the slender petiole, barely 1 cm. long ; 

 glabrous, except for scanty, minute hairs above, and minute 

 spreading pubescence on the veins below. Lateral veins incon- 

 spicuous, 4 or 5 pairs only. Stipules very small, bifid into two 

 curling setae. Corymbs 4-5-fiowered, glabrate. Ovary almost 

 glabrous. Calyx-lohes, 2-2*5 mm. in the mature flower, setaceous, 

 curling ; one in many cases expanded into a narrowly ovate 

 petaloid yellow lamina, 2 x 1'2 cm. or rather larger, acuminate
