6 ACANTHACE® (Clarke). [ Thunbergia. 
long; leaves 2-32 in. long, ovate or triangular, acuminate, purple 
beneath, base truncate or hastate often with acute angles, margin 
sinuate, sparingly toothed, often entire; petioles attaining 1-2 in., 
not winged ; bracteoles 1-2 in. long, elliptic or oblong; ealyx-teeth 
about 12, linear, 3 in. long ; corolla-tube 8-1 in. long, pale yellow ; 
limb 14 in. in diam., white; anthers glabrous, except for a dense 
tuft of long beaded hairs on the triangular acute base of each cell, 
without any linear curved spur; one lobe of the stigma much below 
the other; capsule $ in. long, glabrous; seeds } in. in diam., 
flattened. J. angulata, T. Anders. in Journ. Linn. Soc. vii. 19

Lindau, in Engl. Jahrb. xvii. Beibl. 41, 37, places correctly 7. angulata, Hook. 
(a Madagascar plant), in the section which has the anther-cells spurred at the 
base. The original picture of Hooker (Exot. Fl. t. 166) shows the Madagascar 
plant correctly, the separate enlarged anther incorrectly, but Hooker says his 
picture was taken partly from Cape material. T. Anderson, who united the two 
species, does not appear to have looked at the anthers. 
4. T. Galpini (Lindau in Engl. Jahrb. xxiv. 310) ; glabrous, except 
for the beaded hairs on the anthers; stem repeatedly branched 
upwards; branchlets quadrangular; leaves 2 by } in., elongate- 
triangular, acute, from a subcordate base; petiole 0-7; in. long ; 
bracteoles 2 in. long, broadly oblong ; corolla-tube shortly exceeding 
the bracteoles ; limb 13 in. in diam.; anther-cells (some of them) 
spurred at the base ; style glabrous; one lobe of the stigma below the 
other,

5. T. venosa (C. B. Clarke); fulvous hispid, becoming glabrate ;

lanceolate, obscurely-toothed or nearly entire, nerves primary and 
secondary much raised on the lower surface; petioles 0-1 in. long; 
bracteoles $ in. long, elliptic-lanceolate ; calyx-teeth 12, linear, more 
than 4 in. long; corolla yellow; tube 1 in. long; limb 1 in. in 
diam, ; anther-cells with beaded hairs their whole length, basal spurs 
linear-conic, rather short, scarcely curved; style papillose and white 
hairy near the top; stigmas very large, one lobe below the other ; 
capsule % in. long, glabrous.
