502 XCV. GESNERACEX (BAKER AND CLARKE). | L’pithema. 
circumscissile. Seeds 400 » long, oblong, brown, spirally striated 
longitudinally, on small funicles.— Weak, small, hairy, succulent herbs, 
the African species stemless. Peduncle bearing at its top a one-sided 
or hooded bract which surrounds the dense inflorescence; pedicels hardly 
any, scorpioid, forming apparently a small head.

crenate, with many-celled hairs on both surfaces; nerves 8—9 pairs ;

Except in its larger size this is equal to H, tenue ; Henriques says that Z. tenue 
differs by its palmiuerved leaves ; but I see no difference in the nervation. All the 
Species of Epithema are so similar in structure that the differences in size (which are 
very great in the well-known Z. carnosum) are of very doubtful specific value. 
3. ACANTHONEMA, Hook. f.; Benth. et Hook. f. Gen. PI. ii. 1021. 
Calyx small, deeply 5-lobed. Corolla tubular, oblique; limb of 5 
short rounded lobes. Stamens on the corolla 4 (often only the 2 anticous 
developed), the 2 posticous with a tooth close to the anthers. Disc 
oblique. Ovary 2-celled; the two parietal placentas intruding till they 
nearly meet, bearing numerous ovules on their margins ; stigma emar- 
ginate. Capsule ovoid, small (pericarp very tough), loculicidal. Seeds 
under the recurved margins of the placenta, ellipsoid, 400 » long, brown.— 
Leaf 1, i.e., the other cotyledon disappears; the permanent cotyledon 
grows on and is carried 1-5 in. u p an apparent stem as in some species 
of Streptocarpus. Peduncles 1_4 at the base of the leaf, 0—2 in. long, 
each carrying 1-12 flowers in a lax cyme. (The cross section of the 
ovary depicted in Bot. Mag. t. 5339 must have been taken very near 
the base to show the placentas confluent.) 
1. A. strigosum, look. f. Bot. May. t. 5339. Leaf (cotyledon) 
ovate or oblong, sessile, cordate, thinly hairy on both surfaces, growing 
out to 9 in. long; margin subentire; nerves 20 pairs. Pedicels } in. 
long, with many-celled hairs; bracts at their base minute. Calyx-lobes 
10 12. long, oblong, with many-celled hairs. Corolla-tube % in. long ; 
limb violet-purple. Anthers confluent in pairs; tooth at the top of 
the anticous stamens very small; posticous stamens very frequently
