182 Dr Graham''s Descriptioti of' New or Rare Plants. 



numerous, white, naked, forming two waved lines nearly the whole 

 length of the germen, on each of three parietal receptacles. 



This rare plant, the solitary species of a genus presenting a very compli- 

 cated form of flower, is a native of the Cape of Good Hope. Here, and 

 I suspect in other cases among the Orchidew^ the sudden abstraction of 

 the pollen, mass by the adhesion of the scale at the base of its pedicel to 

 the finger of the' examiner, has given rise to the belief that it starts 

 out from an elastic power. The pedicel, when forcibly extended, con- 

 tracts from elasticity, but never forces the poUen-mass from its case, 

 otherwise than by dragging it after a substance to which the scale at its 

 base had adhered. 



The specimen described was kindly communicated to the Royal Botanic 

 Garden, Edinburgh, by Mr Ayton, from the rich collection at Kew, in 

 1826. It has been always kept in the stove, in soil containing a large 

 proportion of peat, and flowered very freely both last year and this in 

 March and April. The flowers remain expanded for a considerable time.

 Dillwynia juniperina, Lodd. Bot. Cab. t. 401. 



Description. Shrub erect; bark brown. Branches long, slender, 



spreading, rough, from the persisting callous bases of former leaves, 

 pubescent towards their extremities. Leaves crowded, spreading at 

 right angles, straight, smooth, filiform, but channelled above, termi- 

 nated with a rigid straight mucro, and arising from a short sub- 

 erect petiole with a tumid persisting callous base. Flowers termi- 

 nal, capitate, on short pedicels, each of which has two minute lateral 

 and opposite brown bractea; near the top, and each springs from 

 the axil of a bractea, which is somewhat larger and acuminate, but 

 otherwise similar. Calyx bilabiate, and, as well as the jiedicel and 

 younger branches, clothed with adpressed pubescence ; upper lip some- 

 what' compressed laterally, 2-toothed, teeth broad, shoit, blunt, and 

 slightly divaricated ; lower lip shorter, more deeply divided into three 

 narrower pointed teeth. Corolla orange-yellow, vexillum very broad, 

 much reflected, slightly notched, and having connivent, radiated red 

 streaks, proceeding from near the faux, lea^ang in the centre a cordate 

 spot of the same colour as the rest of the limb, claw slender ; alae as long 

 as the vexillum, connivent along their upper edge, spreading at the 

 lower, divaricated at their apices, and standing forwards from the centre 

 of the flower, red in their lower half; carina half the length of the alae, 

 yelloAV, blunt, gibbous below, upper edges connivent. Slametis free, in- 

 cluded in the keel, inserted with the corolla into the tube of the calyx ; 

 filaments subulate, reddish ; anthers yellow, obovate, bilobular, and each 

 lobe furrowed along its outer side, where it subsequently bursts. Stigma 

 capitate, green, reaching as far as the anthers ; style green, hooked ; ger- 

 men green, shorter than the style, covered with white wool; ovules two, 

 round and compressed. 

 This is a ver}' pretty species, first introduced by Messrs Ivoddiges, was 

 subsequently imported by F. Henchman, Esq., and raised in the nursery 

 of Mr IMackay at Clapton, from whence we had a specimen in 1828. It 

 flowered freely in the Botanic Garden, Edinburgh, in the beginning of 

 ]March following, and, like others of the family, remained long in flower. 

 Its identity with the plant of 1 he Botanical Cabinet I have ascertained 

 by a specimen obligingly sent lo me by Mr G. Loddiges.
