LABIATJE. XV. HTPTIS. 



GST 



tubular, with a straight or oblique mouth ; teeth 5, nearly 

 equal, acute, or subulately awned. Corolla with the tube 

 about equal in length to the calyx, 3-4-cleft, sub-bilabiate ; the 

 4 upper lobes quite entire, flat, all distinct, or the upper 2 are 

 joined : lower one abruptly deflexed at the time of florescence, 

 saccate, contracted, and subarticulated at the base. Stamens 

 4, declinate ; filaments free, toothless ; anthers ovate-reniform, 

 with confluent cells. Style about equally bifid at top ; lobes 

 subulate ; stigmas for the most part terminal, minute on the 

 inside of the lobes of the style, rarely altogether stigmatiferous ; 

 disk equal, the lower side generally furnished with an obtuse 

 tooth. Achenia ovoid, oblong, or compressed, smooth, rarely 

 wrinkled, and in some species margined by a flat wing, but 

 never navicular. Herbs or subshrubs. Inflorescence and habit 

 very variable. " Looking to the large number of species, and 

 to the great variety in their habit, it would seem at first more 

 convenient to divide this group into a number of genera ; but 

 on examination the essential characters have proved to be so 

 nearly the same in all, the difference consisting chiefly in the 

 uncertain characters of inflorescence, that I have preferred con- 

 sidering the different groups into which they have been distri- 

 buted as mere sections." Benth. lab. p. 65.

 ing, floccosely-woolly at the base, naked above ; leaves on short

tomentose. Corolla rather shorter than the calycine teeth, 

 white ; upper segments spotted with brown ; lower one some- 

 what rose-coloured.

 hardly interrupted at the base. Bracteas numerous, adpressed, 

 linear-subulate. Fructiferous calyx straight, with subulate

 larger calyxes.

 cate mouth, and subulate teeth. Q. S. Native of the South of
