 l|-l-i- lin. long, oblong to deltoid-ovate, acute or subobtuse. Corolla- 

 lobes very sparingly ciliate, with a median ciliate crest and 1 or more 

 lines of a few hairs on each side. Fruit globose, equalling or shorter

 ochreous.

7. L. senegalense, M. E. Br. Leaves 1-8 in. long, 1-7| in. 

 broad, orbicular or orbicular-oblong, broadly cordate, with a very open 

 sinus at the base, very obtuse, entire or repand at the margin, sub- 

 coriaceous. False petioles often runner-like and bearing 2 or more 

 distant leaves, with 12-30 flowers in a cluster, J-lJ in. below the leaf-

 Sepals 2J-3 lin. long, oblong-lanceolate, acute. Corolla white, ciliate, 

 with a fringed corona at the base of the lobes (Grisehach). Fruit 

 ellipsoid, equalling or shorter than the calyx, G-15-seeded. Seeds f-1 

 lin. long and slightly narrower, J lin. thick, orbicular-oblong, much 

 compressed, sublenticular, rather thickly covered with minute papilla-

Very distinct from all the other African species in its stouter stems or false 

 petioles and pedicels, and the much more compressed seeds, on which (with the 

 exception of those of L. KirJcii, N. E. Br.), the tubercles are more numerous and 

 only half as large as those on the seeds of the other species. The 'flowers, to:*, 

 appear to be larger, but those on the specimens seen are too decayed to permit 

 of examination. See note under L. orbiculatum, Griseb.

8. L. orbiculatum, Griseb. Gen. d- Sp. Gent. 348. " Corolla 

 scarcely overtopping the calyx, fimbriate on the margin, seeds 

 numerous, compressed, granulate-asperate. — Lam. 111. nr. 196G, et 

 Men. indica, ^, Enc. iv., p. 91." 



The above name and description apparently refer to two distinct plants, neither 

 of which was seen by Grisebach. Tlie name L. orbiculatum is transferred from 

 Menyanthes orhiculata. Lam. 111. i. 438, no. 1966, and tlie description is extracted 

 from that given by Lamarck under M. iiidica, var. (i, whilst the drscription of 

 M. oi-biculata is not given at all : it runs as follows : " M. orbiculatu, leaves
