 culis tenuibus axillariis, bracteis foliaceis, bracteolis linearibus. 

 Flores sessiles, sepalis coriaceis ovatis ad oblongo-ovatis acuminatis 

 vel acutis, glabris, apice pilosis ; corolla campanulato-infundibuli-

Hab. Kushiba Eiver, Katanga, Congo ; on the border of the 

 grass plain which occupies the river valley, 4500 ft. alt., in flower, 

 Jan. 27, T. Kassner, n. 2410. 



Shoots 2-2-5 dm. long, slender, barely reaching 2 mm. in 

 thickness, clothed like the leaves with long spreading stiffish 

 hairs. Leaves 3-5-5-5 cm. long, *9-l-8 cm. broad ; petiole 2-4 mm. 

 long. Peduncle 2*5-3 cm. long ; bracts 1*5-2-3 cm. long, bracteoles 

 to 1*5 cm. long. Sepals 6-5 mm. long, the outer three slightly 

 longer than the two inner. Corolla about 3 cm. long. 



A very distinct species of the section Leiocalyx recalling 

 I. simi^lex and I. Wehuitschii in habit, but at once distinguished 

 by the leafy bracts. 



I. SHiRENSis Oliver, a Nyasaland species now brought by 

 Kassner from the Congo — "Binga, Katanga, at foot of the Kunde- 

 lungu Mts., growing under trees on the steep clay sides of a deep 

 washed-out watercourse, at 4000 ft. ; no. 2625, in flower, March." 



Merremia stellata Bendle, described from a specimen from 

 Gossweiler, Angola (open woods at Kului), now brought by Kassner 

 from the Congo — " Kantu, on a flat grassy wet plain on an old ant- 

 heap overgrown with small bushes at 4200 ft. (no. 2374)." The 

 Congo plant differs from the type in that the characteristic stellate 

 hairs are almost confined to the stems and flower-stalks, the leaves 

 being practically glabrous. 



A NEW VAEIETY OF PABNASSIA PALUSTBIS. 



By W. G. Travis & J. A. Wheldon, F.L.S. 



On the coasts of Lancashire and Cheshire Parnassia palustris 

 Linn, occurs in a form which differs in several respects from the 

 inland plant. After a careful study of this littoral form we have 

 come to the conclusion that it is worthy of varietal rank. So far 

 as we know it has not hitherto been described.
