HuiLLA. — An annual, erect herb, branched from the base, rarely 

 simple or nearly so, from 3 in. to scarcely a foot high, the whole plant 

 very sweetly aromatic and beset everywhere with glandular papillae 

 intermixed on the stem and bracts with viscid hairs ; stem cylindrical 

 or somewhat tetragonal, as well as the spreading-ascending branches 

 glaucescent fleshy and brittle ; leaves oblong-obovate, pale or glaucous- 

 green, somewhat fleshy, pellucid-punctate, brittle ; flower-spikes 

 terminal and axillary, distichous or secund, bracteate ; bracts marked 

 below the apex with a large round reddish gland ; calyx shortly 

 tubular, sub-truncate, densely shaggy-glandular outside and on the 

 margin ; corolla purplish, coloured like that of rosemary, tubular- 

 bilabiate i the tube curved, longer than the calyx ; the upper lip 

 trilobulate, somewhat concave ; the lower lip entire, boat-shaped ; 

 stamens 4, didynamous ; filaments ascending, smooth ; anthers 2-celled ; 

 the cells at length confluent, patelliform ; style filiform, shortly bilobed 

 at the apex ; young nutlets 4, globular, smooth. Cultivated in negro 

 gardens about villages (Libata), and occasionally wild in neglected 

 plots ; apparently introduced from eastern or northern regions, for it 

 is altogether wanting from the western coast region. In Cazengo 

 Welwitsch was told that it had come from the further side of the river 

 Cuango beyond Canange ; it is grown for the sake of its fragrance 

 and is chiefly used for making women's pomatum. In elevated rocky 

 places on the Humpata plateau at an elevation of 5300 ft., about 

 Sambo de Ferrao, rather rare ; fl. April 1860 ; also by the Monino, 

 end of May and beginning of June 1860. Native name " Capiana."
