142. Nemia cheiranthus, Berg. cap. 160. Lobelia cheiran- 

 thus, Lin. spec. 1319. Cheiranthus Africanus, flore luteo, 

 Comm. hort. 2. p. 83. t. 42. Corolla deep yellow. It is the 

 great disproportion in length of the 5 divisions of the corolla of 

 this species that was the origin of the generic name. 



Hand-flower Manulea. Fl. June, Aug. Clt. 1795. PL 

 1 foot. 



24 M. PUSI'LLA (E. Meyer, mss. ex Benth. 1. c.) leaves nearly 

 radical, obovate, or oblong, a little toothed ; peduncles nume- 

 rous, scape-formed, erectish ; racemes nearly simple ; tube of 

 corolla hardly exserted ; segments of the limb scarcely unequal, 

 rather shorter than the tube. $ . G. Native of South Africa, 

 at Zilverfontein in Namaqualand. Very nearly allied to M. 

 cheiranthus, but much smaller, and with very much smaller 

 flowers. 



Small Manulea. PI. i to \ foot. ? 



25 M. GARIEPI'NA (Benth. 1. c.) leaves nearly radical, ovate, 

 obovate, or oblong ; peduncles scape-formed, erect, a little 

 branched ; racemes compound, many-flowered ; tube of corolla 

 more than twice the length of the calyx ; segments of the limb 

 unequal. $ . 1 G. Native of South Africa, on the plains of the 

 Gariep, in Namaqualand. This species also comes near M. 

 cheiranthus, but differs in the flowers. In both this and the 

 preceding species the lower segments of the corolla are fre- 

 quently, and sometimes perhaps all of them, obtuse, so as to 

 connect the present section with the two first, ex Benth. 



Manulea. PI. 1 foot.? 



f Species described by Thunberg, which Mr. Bentham, who 

 has written a monograph on the present tribe, has not been able 

 to refer to any of the above.

 fl. cap. 469.) leaves ovate-lanceolate, serrated, villous ; heads 

 globose ; stem erect. $ . ? G. Native of the Cape of Good 

 Hope.

27 M. VIRGA'TA (Thunb. fl. cap. 470.) leaves obovate, ser- 

 rated, villous ; branches panicled ; flowers alternate, remote. 

 $ . G. Native of the Cape of Good Hope. Said to be nearly 



allied to M. titrrltis. 



Twiggy Manulea. PI. 1 foot. ? 



28 M. CEPHALOTES (Thunb. 1. c.) leaves oblong, erosely ser- 

 rated, glabrous ; flowers subumbellate. $ . ? G. Native of the

 serrated, hairy ; flowers axillary. $ . ? G. Native of the 

 Cape of Good Hope.

30 M. THUNBE'KGH ; leaves oblong, serrated, tomentose ; 

 stem erect, hairy. $ . G. Native of the Cape of Good Hope.

LIN. SYST. Didynamia, Angiospermia. Calyx campanulate, 

 5-parted, permanent. Corolla funnel-shaped ; limb equal, 5- 

 parted ; segments obcordate. Stamens 4, didynamous ; anthers 

 small. Stigma of 2 roundish lobes. Capsule small, grooved on 

 one side, 2-valved, 2-celled ; valves bifid ; dissepiment double, 

 formed by the vent in edges of the valves. Seeds ovate, rugged 

 from crowded tubercles. Small, alpine, tufted plants. Radical 



leaves rosulate : cauline ones alternate. Stems simple ; the side 

 ones barren or surculose. Flowers alternate, each rising from 

 the axil of a bractea, disposed in terminal simple racemes. 

 Corollas purple or red. 



1 E. ALPI'NUS (Lin. spec. 878.) leaves tufted, spatulate, deeply 

 serrated, hairy; racemes sub-corymbose. If.. H. Native of 

 the alps of Europe ; as of Germany, Switzerland, Pyrenees, 

 South of France. Curt. bot. mag. 3. t. 310. Corollas purple.

Alpine Erinus. Fl. March, June. Clt. 1739. PI. i foot. 



2 E. HISPA'NICUS (Pers. ench. 2. p. 147.) plant smaller than 

 the preceding, branched, and glabrous ; leaves tufted, bluntly 

 serrated; racemes elongated. TJ.. H. Native of Spain, near 

 Pancorvo, Clemente. Corollas purple. 



Spanish Erinus. Fl. March, June. Clt. 1739. PI. | foot. 



Cult. These are pretty little alpine plants, and are, therefore, 

 very desirable for the decoration of rockwork or old walls, for 

 which purposes no plants can be better fitted, as they grow in 

 close tufts, and produce their numerous purple blossoms during 

 most of the summer months. They are either propagated by 

 division or by seeds ; but they succeed best when allowed to 

 scatter their seeds. 



Tribe VII. 



BUDDLIE'jE (this tribe only contains the genus Bud- 

 dlea.) D. Don. in edinb. phil. journ. vol. 19. July, Oct. 

 1835. Calyx campanulate, 5- toothed. Corolla tubular; limb 

 4-5-cleft, equal, spreading. Stamens 4-5, nearly equal, in- 

 closed ; anthers composed of 2 parallel, distinct cells. Stigma 

 clavate, 2-lobed. Capsule crustaceous ; dissepiment constituted 

 from the inflexed edges of the valves, inserted in the thick 

 spongy placenta. Seeds angular, scobiform ; testa loose, mem- 

 branous. Albumen fleshy. Embryo almost the length of the 

 seeds ; cotyledons oblong, compressed ; radical very short. 

 Shrubs with usually quadrangular branches. Leaves opposite, 

 reticulately-veined. Flowers terminal, capitate, spicate, or pani- 

 cled, usually orange-coloured. This tribe is analogous in habit 

 to many Verbenaceae.

 Buddie, who is often mentioned in Ray's synopsis. His dried
