422 CIX. ACANTHACEE. (C. B. Clarke) [Dedalacanthus. 
capitate or oblong dense, bracts leaf-like glabrous often undulate-crenate, 
corolla 1} in. blue. 
MALAY PENINSULA; Tenasserim, Helfer (Kew Distrib. n. 6176), Beddome ; 
Tavoy and Moulmein, Parish. 
Whole plant lineolate with raphides, Stems erect, elongate, tetragonous, leafy 
upwards. Leaves 5} by 2} in., tip long acuminate, base shortly acuminate ; nerves 
7-8 pair; petiole 0-14 in. Flowers often appearing densely clustered at the nodes on 
shortened axillary spurs; bracts 1-12 in., leafy, imbricated usually densely sometimes 
laxly ; bracteoles Y in., linear-lanceolate. Calyx 4 in., divided half-way down; lobes 
narrow-lanceolate, whiteued, puberulous, Corolla-limb 2 in. diam. Anthers included. 
Capsule 1 in., glabrous.—This much resembles D. suffruticosus, but the leaves are 
conspicuously lineolate. T. Anderson has overlooked the true bracteoles; they are 
exactly similar in size, form and situation to those of other species. The bracts 
(bracteoles of T. Anders.) are 1 to each flower ; when they are opposite on the spike 
and the flower in the axil of one is aborted, they appear superficially 2 to each flower; 
as is the case often in D. montanus and several other species and genera. 
XV. HEMIGRAPHIS, Nees. 
Herbs or shrubs. Leaves opposite, toothed or subentire. Flowers 
sessile, in heads or spikes, rarely solitary; heads terminal or quasi- 
axillary on shortened branchlets, rarely (in H. flava) panicled ; bracts 
imbricated, large, l-fld.; bracteoles small, narrow, or 0. Calyx 9-partite 
nearly to the base; segments 5, subequal, linear-lanceolate or lanceolate. 
Corolla long-tubular, lower half cylindric, upper funnel-shaped or ventri- 
cose; lobes 5, rounded, subequal, sinistrosely contorted, blue or yellow. 
Stamens 4, didynamous, included or nearly so; anthers oblong, 2-celled, 
muticous, sometimes triangular, bases acute. Style long, stigma of one 
linear and one very short lobe; ovules 3-8 in each cell. Capsule linear 
or linear-oblong, 6-20-seeded nearly from the base. Seeds compressed, 
discoid, brown when dry, apparently glabrous with a white margin, when 
wetted densely hairy with white long unicellular hairs, each with numerous 
annular thickenings.—Species 20, Indian, Malayan, a few Chinese and 
Japanese. l l 
Sect. 1. Corolla tubular-ventricose, limb blue. Longer filaments gla- 
brous in their upper half or very nearly so.
