2-lipped with a small ventral lobe, dorsal margin }-1 lin. long, umbonate 
or obtusely keeled, ventral margin 4—} lin. long. Receptacle and calyx 
together cupular or suburceolate, 24-24 lin. Jong. Calyx deeply lobed, 
g-§ lin. long. Corolla about 14 in. long; tube 24-3 (more rarely 5) lin. 
long, with 5 ascending membranous flaps inserted on the adnate part 
of the filaments about 1 lin. above the base of the tube, flaps broadly 
ovate or oblong, rounded, # lin. long, 3—? lin. broad at the base; lobes 
oblanceolate-linear, broadened into the base, about 1} in. long, with 
about 5 oblique folds arising on each side of the adnate filaments, 
the lowermost 1 lin. of each lobe reduplicate-valvate, thus forming 
5 gibbosities in bud. Filaments inserted 34—4 lin. above the base of the 
corolla-lobes, 5 lin. long; anthers linear, 4-4} lin. long. Disc about

In Fritrea, according to Schweinfurth (l.c.), Z. Acacie grows principally on 
species of Acacia—e.g., A. etbaica, Schweinf.—but is also parasitic on trees belonging 
to the most widely separated orders. 
17. L. nummulariezfolius, Franch. in Journ. de Bot. i. 135, in obs. 
Glabrous, glaucous-pruinose. Branchlets slender, fuscous. Leaves 
subopposite, sessile, small, orbicular or broadly ovate, cordate and 
amplexicaul at the base, thick. Pedicels short; bract obliquely cupular, 
obscurely trilobed, the middle lobe larger than the lateral ones, rounded. 
Calyx very short, truncate. Corolla over 1 in, long, reddish, glabrous, 
‘divided to a fourth part” (? from the base) ; lobes linear, narrowly 
spathulate, reflexed about the middle. Filaments glabrous; anthers 
linear, adnate, connective slightly produced above the cells, obtuse.— 
Lapinostemma nummulariifolium, Van Tiegh. in Bull. Soc. Bot. France, 
xlii. 258. 
Nile Land. Italian Somaliland: Modie Valley, Révoi/. 
Known to me only from Franchet’s very imperfect description. As Van Tieghem 
has placed it in the genus Zapinostemma, it is probably allied to L. Acacie.
