Cult. See Marrubium for the culture of the perennial herba- 

 ceous kinds ; and Lasiocorys for that of the shrubby species. 



LXXXVIII. LASIO'CORYS (from Xa<r>c, lasios, wool; 

 and ropvc, korys, a helmet ; in reference to the outside of the 

 galea of the corolla being very hairy.) Benth. lab. p. 600.

 late, equal, 1 0-nerved : teeth 5, ovate, rarely furnished with mi- 

 nute teeth in the sinuses. Corolla with an inclosed tube, which 

 is annulate inside, and a bilabiate limb ; upper lip entire, con- 

 cave, erect, very hairy outside : lower lip spreading, scarcely 

 longer, trifid ; the middle segment hardly broader than the lateral 

 ones, emarginate. Stamens 4, didynamous : lower 2 the longest, 

 ascending ; filaments naked at the base ; anthers approximating 

 by pairs under the upper lip, 2-celled : cells divaricate. Lobes 

 of style subulate : lower one the shortest, and sometimes very 

 short, stigmatiferous towards the apex. Achenia dry, trique- 

 trous, obtuse at top. Branched shrubs. Leaves entire or 

 toothed. 



1 L. CAPE'XSIS (Benth. lab. p. 600.) leaves almost quite en- 

 tire ; whorls 2-4-flowered ; calycine teeth one half shorter than 

 the tube. I? . G. Native of the Cape of Good Hope. Young 

 branches clothed with white tomentum : adult ones canescent, 

 or nearly glabrous. Leaves fasciculate, nearly sessile, oblong or 

 cuneiform, obtuse, canescent from tomentum, as well as the ca- 

 lyxes, &c. Corolla whitish. Upper lobe of style usually very 

 short. 



Cape Lasiocorys. Shrub. 



2 L. ABYSSI'XICA (Benth. lab. p. 600.) leaves toothed at 

 apex; whorls 6-1 0-flowered ; calycine teeth subulately acumi- 

 nated, about equal in length to the tube. ^. G. Native of 

 Abyssinia. Leucas quinquedentata, R. Br. append, to Salt, 

 abyss. Habit of L. integrifolia. Branches pubescent. Leaves 

 longer and greener. Calyx scarcely tomentose. Upper lobe of 

 style one half shorter than the lower one. 



Abyssinian Lasiocorys. Shrub. 



Cult. A light rich soil will suit the species of this genus ; 

 and cuttings will strike root readily in the same kind of earth, 

 with a hand-glass placed over them ; but if seeds ripen, this will 

 be unnecessary. 



LXXXIX. RO'YLEA (named in honour of John Forbes 

 Royle, M.D. surgeon in the East India Company's Service; 

 late superintendent of the botanic garden at Saharumpur ; 

 now Professor of Materia Medica in King's College, London ;

LIN. SYST. Didynamia, Gymnospermia. Calyx tubular at 

 the base, 10-nerved; limb 5-cleft ; segments erect, oblong, 

 membranaceous, reticulately veined, equal. Corolla shorter 

 than the calyx ; tube inclosed, annulate inside ; limb bilabiate ; 

 upper lip erect, entire, arched : lower lip spreading, tri6d, hav- 

 ing the middle lobe entire. Stamens 4, didynamous, ascending 

 under the upper lip : lower 2 the longest ; anthers approxi- 

 mate by pairs, 2-celied : cells divaricate, at length sub-confluent. 

 Style almost equally bifid at top ; lobes subulate, stigmatiferous 

 at apex. Achenia dry, obtuse at apex. Allied to Ballola and 

 Otostegia, from which it differs only in the calyx.

 Deyra Dhoon, Wall. ; Hurdwar and Sirinaghur, Hardwick ; 

 Himalaya, Royle. Phlomis calycina, Roxb. fl. ind. 3. p. 11. 

 Ballota cinerea, D. Don, prod. fl. nep. p. 11 1 A much branch- 



ed, erect shrub. Branches cinereous from tomentum. Leaves 

 numerous, petiolate, ovate, acute, subcordate, coarsely and 

 bluntly serrated, 1 to lg inches long, pilose on both surfaces, 

 green above and hoary beneath ; floral leaves conforming to the 

 others, but gradually smaller. Whorls 6- 1 0-flowered ; cymes

 feet.

XC. OTOSTE'GI A (from ovc tn-oc, out otot, an ear ; and

 being prolonged.) Benth. lab. p. 601. Phlomis species, Vahl. 

 Molucella species, R. Br. 



Lix. SYST. Didynamia, Gymnospermia. Calyx tubular at 

 the base, 10-nerved; limb sub-bilabiately and membranaceously 

 prolonged : upper lip short, entire, or triangular : lower lip 

 large, ovate, obtuse. Corolla with an inclosed tube, which is 

 annulate inside, and a bilabiate limb ; upper lip oblong, con- 

 cave, entire, erect, very hairy outside : lower lip spreading, 

 trifid : middle lobe broader, emarginate. Stamens 4, ascending, 

 didynamous, the lower ones the longest ; filaments naked at the 

 base ; anthers approximate by pairs under the superior lip, 2- 

 celled : cells divaricate. Style somewhat equally bifid at top ; 

 lobes subulate, stigmatiferous at apex. Achenia dry, obtuse at 

 apex. Shrubs. Whorls loosely many- flowered. Corollas white. ? 

 This genus differs from Roylea, Ballota, and Leucas, in the 

 calyx ; and from the latter genus in the divisions of the style.

 Molucella repanda, R. Br. Append, to Salt's Abyss. Allied to

 and in the calyxes being more villous, and in the form of the 

 upper lip of the corolla.
