Ecbolium.] ACANTHACER (Clarke), 79 
pollen subglobose with 3 large stopples and 3 bands continued to the 
poles ; ovary glabrous, lower part of style thinly hairy. 
Coast Recion: Komgha Div.; near the mouth of the Kei River, 200 ft., 
Flanagan, 2351! 
This species is very close to E. barlerioides, Lindau ; it differs by the narrower 
bracts and long-petioled leaves. . 
Imperfectly known Species. 
2. E. protractum (Schinz in Mém. Herb. Boiss. x. 64). 
EASTERN REGION: Delagoa Bay, Kuntze. 
This is defined as Ecbolium protractum, O. Kuntze, Rev. Gen. PI. iii. pt. 2, 
248. This may not improbably mean Justicia pulegeioides, EH. Meyer; but it 
must be recollected that the plant Justicia pulegioides, E. Meyer, is the type of 
the genus Chiwtacanthus, Nees. 
XXVI. ISOGLOSSA, Oerst. 
Calyx 5-partite nearly to the base; segments 5, linear, 1-2 in. 
long. Corolla white, with some rose, yellow or purple spots, 2- 
lipped, 1—2 in. long (much longer in the subgenus Ramusia) ; anticous 
lip not much shorter than the tube, with 3 oblong or ovate lobes. 
Stamens 2, without rudiments of others; filaments glabrous; one 
anther-cell completely above the other, elliptic; pollen globose, 
much flattened, almost lenticular, with one stopple in the centre of 
each smooth circular face. Pistil glabrous; style hardly 2-lobed; 
ovary oblong-ellipsoid with 2 ovules in each cell. Capsule 1-2 in. 
long, usually 4-seeded at the top, lower half much narrower (except 
in I. origanoides). Seeds tubereular-scabrous, 
Leaves ovate or elliptic; inflorescences panicled ; floral leaves and bracts 
smull, or larger and lanceolate or spathulate-obovate. 
Species about 30, in Africa and the Mascarene Islands, besides a few in India, 
The Cape species (except subgenus Ramusiu) agree most closely in habit, 
corolla, stamens, and pistil, and are consequently difficult to distinguish, both 
among themselves and from some Tropical African species,
