Schimper, 1660, contains, by admixture, both 4. equinoctiale and A. tacaz- 
zeanum. -A, Richard describes therefrom his 4. tacazzeanum as having six seeds to 
each cell of the capsule, so that his plant was certainly 4. equinoctiale, Kunth. 
Lamprodithyros tacazzeanus, Hassk. in Peters, Reise Mossamb. Bot. 531, is said to 
be Aneilema tacazzeanum, Walp. Ann, iii. 658, which is merely copied, with a little 
confusion, from A. Richard ; but Hasskarl describes his Zamprodithyros tacazzeunus 
at great length, and says the ovules were only 2-1 in each cell; so that Hasskarl’s 
plant was really the tucazzeanus of Hochsteiter, excluding the citation of Walpers. 
There is ample evidence of the variation in the colour of the petals; the different- 
coloured flowers have been esteemed different species by many collectors. 
3. A. tacazzeanum, Hochst.ex C. B. Clarke in DC. Monogr. Phan. 
iii. 222, not of A. Rich. Thinly hairy. Stems 1—2 ft. long, weak, de- 
cumbent at the base and there sometimes divided, rooting often at the 
lower nodes. Leaves 3 by 1 in. (in Hochstetter’s two ‘“ types ”), elliptic, 
acute, base contracted, often subpetioled. Inflorescence terminal, pe- 
duneled, 1? by 14 in., very lax, obscurely pubescent; cyme-peduncles 
alternate ; bracts less than } in. long, ovate; bracteoles less than ¢ in. 
long, obovate. Sepals about } in. long, elliptic, concave. Corolla 
smaller than in 4. eguinoctiale, appears to have been yellow. Ovules 
3-2 in each cell. Capsule nearly 4 by 4 in., white, truncate, with the 
two upper angles acute, mostly 2-celled, with 3-1 seeds in each cell.—

This is a much weaker plant than A. equinoctiale, the capsule smaller, with often 
only 2-1 seeds in each cell. The example of Schweinfurth, 427, is much stonter 
than Schimper’s, with larger inflorescence and 3 seeds to each cell; this is separated 
from the smaller examples of A. equinoctiale by the smaller, more concave elliptic 
sepals. Hua (in Bull. Mus. Hist. Nat. Par. i. 121) appears to draw the line between 
the two species at a different point. 
Schweinfurth reduces here A. Ehrenbergii, C. B. Clarke (which see No. 27 helow); 
and A. Forskalai, Kunth. The latter is fully described as Commelina paniculata by 
Vahl (Enum. ii. 179), who appears to have had Forskal’s plant; and who describes 
inter alia “ peduncles lateral and terminal, paired, with a sheath 3 in. long at the base 
of each”; so that this plant must have been very remote from 4. tacazzeanum, and 
was almost certainly a species of Commelina.
