HuiLLA. — No notes. Fl. Simple, or nearly so, 2 to G in. high 

 flowers rather smaller. Probably a form of this species. No. 3227. 



This species differs from T. scahin by its longer slender corolla-tube 



6. T. aprica Hiern, sp. n. 



An erect or ascending, sub-scabrid, annual herb, 4 to 12 in. high 

 simple or branched from the base ; stem and alternate branches 

 slender, often purplish, scabrid with whitish short hairs above 

 upper branches few or lax ; middle internodes mostly longer 

 than the leaves, the lower and uppermost ones shorter ; leave 

 opposite, linear or nearly so, acute or pointed and apiculate at the 

 apex, slightly or scarcely narrowed, or in the case of the upper 

 most ones at the base of the inflorescence dilated at the base 

 sessile, glabrate or scattered with short stiff whitish hairs, rather 

 rough, pale grey-green above, yellowish or purplish green 

 beneath, sub-erect except the uppermost ones at the base of the 

 inflorescence, ;| to 1| in. long, uni-nerved ; the margins cartilagi- 

 nous, thickened, a little rough ; stipules adnate to the bases of 

 the leaves, sheathing, terminating in a few or several more or 

 less prolonged setae, glabrous and shining inside ; flowers about | 

 in. long, very numerous, slender, sessile or subsessile, in hemi- 

 spherical bracteolate terminal heads of g in. in diameter with the 

 one or two uppermost paiis of spreading leaves and their stipules 

 forming a kind of involucre ; bracteoles flliform, not exceeding 

 the calyx ; calyx nai-row, compressed, ^\ in. long ; the tube 

 small, glabrous except some scattered minute scales ; the limb 

 bipartite ; the segments green, opposite, equal, i in. long, 

 narrowly linear-lanceolate, acute, ciliate; corolla white-violet- 

 coloured, salver-shaped ; the tube slender, y\ in. long, glabrous ; 

 the throat glabrous ; the lobes 4, lanceolate, glabrous except a 

 few setae outside near the tip, y',5 in. long, valvate in the bud, 

 spreading in the open flower ; stamens 4, exserted ; filaments 

 minutely puberulous, inserted at the top of the tube of the 

 corolla between its lobes, longer than the narrowly oblong anthers ; 

 disk fleshy, cushion-shaped, glabrous ; style flliform, minutely
