586 LXXXVII. GENTIANEE (BAKER AND BROWN). [Limnanthemum. 
below the leaf-blade. Pedicels }-1} in. long, }—2 lin. thick. Sepals 
14-14 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 
than the sepals, 2-10-seeded. Seeds compressed-globose, } lin. in 
diam., } lin. thick, subcarinate, thinly covered with small and very 
prominent tubercles, which are sometimes absent from the centre, 
ochreous.

Probably to this species should be referred L. niloticum, Gilg in Baum, Kunene- 
Sambesi Exped., 335, collected in Angola, in swamps on the banks of the River 
Kubango, above the Quatiri River, Bawm, 400, and in muddy places on the River 
Cunene, above Humbe, Baum, 103. “Flowers white.” 
7. L. senegalense, V. #. 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, }—-14 in. below the leaf- 
blade, stout, 1-3 lin. thick. Pedicels 1-24 in. long, stout, } lin. thick. 
Sepals 24-3 lin. long, oblong-lanceolate, acute. Corolla white, ciliate, 
with a fringed corona at the base of the lobes (Grisebach). Fruit 
ellipsoid, equalling or shorter than the calyx, 6-15-seeded. Seeds §-1 
lin. long and slightly narrower, 4 lin. thick, orbicular-oblong, much 
compressed, sublenticular, rather thickly covered with minute papilla- 
like tubercles.—Z. orbiculatum, Griseb. Gen. & Sp. Gent. 348, and in

(ex Lamarck), 
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 ZL. Kirkii, N. BE. Br.), the tubercles are more numerous and 
only half as large as those on the seeds of the other species. The flowers, toc, 
appear to be larger, but those on the specimens seen are too decayed to permit 
of examination. See note under ZL. orbiculatum, Griseb. 
Imperfectly known species.. 
8. L. orbiculatum, Giriseb. Gen. & Sp. Gent. 348. Corolla 
scarcely overtopping the calyx, fimbriate on the margin, seeds 
numerous, compressed, granulate-asperate—Lam. Ill. nr. 1966, et 
Men. indica, 8, Enc. iv., p. 91.” 
The above name and description apparently refer to two distinct plants, neither 
of which was seen by Grisebach. The name Z. orbiculatum is transferred from 
Menyanthes orbiculata, Lam. Ml. i. 438, no. 1966, and the description is extracted 
from that given by Lamarck under ©, indica, vay. B, whilst the description of 
MM, orbiculata is not given at all: it runs as follows: “ M. orbiculata, leaves
