LABIATE. CIV. STENOGYNE. CV. PRASIUM. CVI. AMETHYSTEA. 



length divaricate. Style almost equally bifid at top, with subu- 

 late lobes ; stigmas minute. Achenia fleshy. Branched, pro- 

 cumbent, ascending or erect herbs, with divaricate subscandent ? 

 branches. Leaves usually coriaceous, crenated. Whorls about 

 6-flowered, axillary, distant, or approximate at the tops of the 

 branches. Floral leaves similar to the cauline ones. Bracteas 

 small, subulate, or almost wanting. This genus differs chiefly 

 from Phyllostegia in the form of the style and corolla, and in 

 the axillary inflorescence.

7 S. NELSONI (Benth. lab. p. 655.) glabrous ; leaves petiolate, 

 ovate, rather flaccid ; whorls axillary, distant ; fructiferous pedi- 

 cels longer than the calyxes ; corolla nearly glabrous, 3-4 times 

 longer than the calyx. I/ . ? G. Native of the Sandwich islands, 

 Nelson. Allied to S. scrophularioides, but differs in the larger

LIN. SYST. Didynamia, Gymnospermia. Calyx campanulate, 

 10-nerved, irregularly bilabiate ; upper lip shortly trifid ; lower 

 lip deeply bifid ; all the segments ovate and foliaceous. Corolla 

 with an inclosed tube, furnished with a ring of scale-like hairs 

 inside, and a bilabiate limb ; the upper lip ovate, entire, and the 

 lower lip trifid : the middle segment the largest and entire. Sta- 

 mens 4, ascending under the upper lip ; anthers 2-celled : cells 

 at length divaricate. Style about equally bifid at top, with subu- 

 late lobes ; stigmas minute. Achenia fleshy.

 with some of the young leaves hispid. Leaves i to 1 inch long, 

 ovate, acute, roundly truncate at the base or subcordate, irregu- 

 larly serrate crenated ; floral leaves similar, or the upper ones 

 are smaller and more entire, all exceeding the calyxes. Whorls

 rollas white or pale purple, glabrous. Stamens inclosed. 



Greater Prasium. Fl. June, Aug. Clt. 1699. Shrub 1 to 2 

 feet. 



Cult. This is a curious evergreen small shrub, which will sur- 

 vive our milder winters in the open air if grown in a dry sandy 

 or gravelly soil, in a sheltered situation ; but in moist strong 

 ground it is sure to perish. A reserve plant or two should be 

 grown in pots, that they may be sheltered by placing under a 

 frame in winter. The plant is readily increased by cuttings and 

 seeds. 



Tribe XI. 



AJUGOI'DEjE (from Ajuga, Bugle; and idea, similar; 

 this tribe contains genera agreeing with A'juga in the characters 

 given below.) Benth. lab. p. 657. Upper lip of corolla some- 

 times very short, sometimes cleft, with cast down, rarely erect, 

 arched segments ; lower lip elongated. Stamens 2-4, ascending, 

 usually exserted, opposite the lip. Achenia more or less reticu- 

 lately wrinkled. In many Ajugoidece, especially in some Teucria, 

 A'juga, Cymaria, &c., the ovarium is less deeply cleft than in 

 other Labialce ; and in Cymaria it is very evidently bipartite, 

 with bifid divisions, instead of being equally 4-parted ; thus con- 

 necting the tribe with the closely allied order of Verbenacecc, ex 

 Benth. 



CVI. AMETHY'STEA (so called from the amethystine 

 colour of the flowers.) Lin. gen. no. 34. Schreb. gen. no. 45. 

 Gaertn. fruct. 1. p. 315. t. 66. Juss. gen. 111. Benth. lab. p. 

 657. 



LIN. SYST. Diandria, Monogynia. Calyx sub-globose, cam- 

 panulate, erect, equal, 5-toothed. Corolla having the tube 

 shorter than the calyx, exannulate inside, and a declinate limb ; 

 the 4 upper lobes nearly equal, and cast down, and the lower 

 lobe larger. Stamens 2, (inferior,) ascending, exserted between 

 the upper segments of the corolla; the rudiments of the 2 upper 

 ones minute and filiform ; aniliers 2-celled : cells at length diva- 

 ricate and sub-confluent. Style almost equal, bifid at apex. 

 Achenia reticulately wrinkled. This genus only differs from 

 Teucrium in the abortion of the upper stamens. In habit it 

 closely resembles Teuci ium corymbosum.
