spreading wide, having clioii erect petioles, veinleee, dark green and 

 broadly channelled above, paler below, and there with a few adpressed 

 hairs upon the revohite entire edges, and on the strong middle rib which 

 is slightly depressed along its centre ; hairs produced at the base. 

 Flowers in distant verticels towards the extremities of the branches, 

 large, handsome, and solitary in the axils of scarcely diminished leaves, 

 which are longer than them. Peduncles thrice as long as the petioles, 

 somewhat silky, with adpressed hairs, and having at the apex two op- 

 posite adpressed subulate persisting bracts. Calyx silky, like the pe- 

 duncle, bilabiate, upper lip bifid, segments ovato-subulate, refiexed ; 

 lower lip tripartite, segments spreading, longer, narrower, and more 

 acute than those of the upper lip. Corolla of nearly uniform lilac ; vex- 

 illum (9 lines across) three times as long as the calyx, reflexed, sub- 

 rhomboid, notched in the centre, slightly striated, and having an obcor- 

 da to-linear bright yellow spot towards its nearly white claw ; alec rather 

 shorter than the vcxillum, falcato-spathulate, edges vertical, nearly 

 without tooth, claw short; keel half the length of the aloe, blunt, its 

 petals cohering only in the middle, the claws longer than those of the 

 ala?. Stamens included within the keel, free, the two upper occasionally 

 abortive; filaments pale greenish, glabrous ; anthers yellow, subrotund ; 

 pollen yellow, granules minute, oblong. Pistil rather shorter than the 

 lower stamens, rather longer than the upper, everywhere glabrous ; 

 stigma capitate, verrucose ; gernien green ; ovules about four. 

 This is a remarkably pretty spscies, and was raised at the Botanic Gar- 

 den in 183G from Australian seeds, which were obligingly given to me 

 by Alex. G. Sneirs, Esq. of Culcreuch, but I do not know from what 

 part of the country the seeds were obtained. The plant has been kept 

 in the greenhouse, with the usual treatment of Australian plants, and 

 flowered for the first time, but then abundantly, in February and March 

 1841.

 Description. — Stem erect, round, sparingly branched ; branches zigzag, 

 villous, green. Lowes alternate, on short stout channelled petioles, 

 rigid, wrinkled, spreading wide, dark green, and rough, with very shoit 

 hairs above, lighter and villous below, cordato-ovate, acuminate, the 

 apex of the upper ones revolutc, the edges reflexed, simply dentate ; 

 middle rib and veins very prominent below, channelled above. Pe- 

 duncles solitary, axillary, erect, half as long as the leaves, villous, with- 

 out bracts. Calyx green, villous, tube turbinato-hcmispherical,with ten 

 strong ribs, and as many round glands between the apices of these ; limb 

 5-purtite, segments twice as long as the tubo, subulate, diverging at the 

 apex. Corolla five times as long as the calyx, purplish-red ; tube en- 

 tire, slightly defloxed, contracted at the throat, and for a space equal to 

 the length of the calyx segments at the base, where it is deeply marked 

 by five grooves, in the centre inflated and compressed laterally ; limb 

 5-partite, segments subequal, linear-lanceolate, acute, slightly hairy 

 within, the two upper straight and paler within, the lateral one spread- 

 ing or reflexed, slightly falcate downwards, the lowest revolutc, and, as 

 well as the lateral ones, nearly white. Stamens as long as the corolla ; 

 filaments inserted along with this into the top of the calyx, adhering to
