I have been unable to sort this species into varieties. The plants named by 
Lindau Z. latifolia, Hochst. (Holst, 8858 ; Volkens, 1652) are identical with those 
named by him H. verticillaris, Solander (Holst, 3492, 9148), from the same 
locality : but they are not exactly H. latifolia, Hochst., which is founded on Kotschy, 
296, and has ovate glabrous leaves 4 in. broad. H. latifolia, Nees, has leaves rather 
larger than usual (attaining 4 by 12 in.), but not differing in form from those of 
H. verticillaris, H. mollis, T. Anders., from the Congo, is remarkably like the 
typical Cape H. verticillaris. The most distinct form (included in the above list of 
numbers) is Schweinfurth’s 128, collected in Gallabat (there are several examples like 
it from the Mozambique region), named by Schweinfurth & Lindau H. latifolia, 
from which it appears to differ considerably ; the leaves are narrowly elliptic, much 
acuminate, the sepals are united scarcely 1 their length, the 2 outer bracts are united 
scarcely 3 their length, and with many spreading long white hairs. Nees says (in 
Linnea, xv. 376) that this species “varies by having 4 didynamous stamens.” I 
have never met with 4 stamens in any plant of the Justicioid series. 
Var. 8 glabra, S. Moore in Journ, Bot. 1880, 363. Almost glabrous, except the 
inflorescence. Leaves attaining 1 by 4-3 in. Bracts pubescent, and also with some 
scattered white longer hairs, 
Lower Guinea. Angola, Welwitsch, 5059! 
S. Moore is probably rigbt in regarding this as a depauperated state of H. verti- 
evllaris ; but it is perhaps as well entitled to be made a species as any of the species 
which follow. 
16. H. Preussii, Lindau in Engl. Jahrb. xx. 48. Leaves up to 5 
by 1} in., elliptic, long acuminate, pubescent on the nerves and with 
Scattered hairs, very shortly narrowed into the petiole ; otherwise as 
H. verticillaris, R. Br. 
Upper Guinea. Cameroons: Buea, 2500 ft., Preuss, 755 ! 
This certainly does not match any of the numerous examples above referred to 
H, verticillaris, but it is difficult to say in what its specific difference exists. Lindau 
says the “ bracteoles are adnate to the 2-toothed involucre ” (which he states of some 
other species of Hypoestes). There is no union between the bracteoles and bracts ; 
but, as in many Acanthacee, the bracteoles cling or stick somewhat to the bract which 
1s external to them. 
17. H. violaceotincta, Lindau in Kugl. Jahrb. xxiv. 323, In- 
florescences axillary and terminal, very compound panicled. Spikelets 
small; two outer bracts hardly exceeding } in. in length; otherwise as 
4. verticillaris, R. Br. 
Upper Guinea. Sierra Leone: Bafodeya, Scott-Elliot ! Togoland: Misahohe,
