252 XCVIIl. ACANTHACEE (CLARKE). [ Hypoestes. 
Leaves rather large. Bracts with some spreading white long hairs. The plant 
resembles much the large-leaved forms of the West African H. verticillaris 
(i.e. H. latifolia, 8 Nees). But Holst, 2265, from Usambara (marked H. verticillaris 
by Lindau) appears the same as H. violaceotincta. 
18. H. tanganyikensis, ('. 2. Clarke. Inflorescences axillary and 
terminal, very laxly panicled; flowers mostly solitary (not clustered), 
4-4 in. apart, white (Whyte). Two outer bracts to the spikelet } by 
zz In., subequal, connate about 4 their length, linear-oblong, subspathu- 
late; otherwise nearly as H. verticillaris.

Imperfectly known species. 
19. H. grandifolia, Lindau in Engl. Jahrb. xx. 49. Stem glabrous. 
Leaves up to 44 by 24 in., pubescent on the nerves beneath. Two 
outer bracts of the spikelet united 3 their length, exceeding 4 in. in 
length, hairy, enclosing 2 flowers. 
Nile Land. Bongo, Schweinfurth, 2613. 
The detailed description by Lindau fits very well many of the larger examples re- 
ferred as forms to H. verticillaris, R. Br., as, for instance, to Schweinfurth, 1066, from 
the White Nile; but though in this 1066 there is a rudiment of the second flower 1m 
the spikelet, I find no 2-flowered spikelets. 
The plant was not found at Berlin. 
56. RUNGIA, Nees; Benth. et Hook. f. Gen. Pl. ii. 1120. 
Corolla, stamens, pistil as of Justicia, sect. Betonica. Placente 0 
ripe fruit rising elastically from the base of the capsule, throwing out 
the seeds.—Spikes strobilate ; bracts in 4 ranks (whereof 2 alternate 
are sterile), much larger than the calyx, broad with prominently 
scarious margins. 
Species 20, in the warmer parts of the Old World. 
Bentham describes the inflorescence, “primarial bracts superposed in pairs, 
lower of each pair sterile, upper bearing a flower”; which is correct but he places 
the genus in his subtribe Diclipterea, to which he attributes “bracts 2 (or 4) val- 
vately adpressed together, including one or several flowers.” This definition applies hed 
Dicliptera, Peristrophe and Hypoestes, but cannot be made to apply to Rungia 
in which the inflorescence is as that of Justicia, sect. Betonica (or of Adhatoda), 
but with 2 ranks of bracts empty,
