capitate or oblong dense, bracts leaf-like glabrous often iindulate-crenate, 

 corolla 1^ in. blue.

Whole plant lineolate with raphides. Stems erect, elongate, tetragonons, leafy 

 upwards. Leaves h\ by 2J in., tip long acuminate, base shortly acuminate; nerves 

 7-8 pair; petiole O-I4 in. Flowers often appearing densely clustered at the nodes on 

 shortened axillary spurs ; bracts 1-1| in., leafy, imbricated usually densely sometimes 

 laxly; bracteoles ^ in., linear-lanceolate. Cah/x J in., divided half-way down; lobes 

 narrow-lanceolate, whitened, puberulous. Corolla-limb | in. diam. Anthers included. 

 Capsule 1 in., glabrous. — This much resembles D. suffrutioosus, 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.

'Herbs or shrubs. Leaves opposite, toothed or subentire. Flowers 

 sessile, in he?ids or spikes, rarely solitary ; heads terminal or quasi- 

 axillary on shortened branohlets, rarely (in S. flava) panioled ; bracts 

 imbricated, large, 1-fld. ; bracteoles small, narrow, or 0. Calyx 6-partite 

 nearly to the base ; segments 6, subequal, linear-lanceolate or lanceolate. 

 Corolla long-tubnlar, 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. 



Sect. 1. Corolla tubnlair-veijtricose, limb blue, lion^er Jilaments gla- 

 brous in their upper half or very nearly so.
