172 Dr Graham's Description of New or Rare Plants. 



Stylidium hirsutum, Br. Prodr. FJor. Nov. Holland. 568.— mSpreng. Sn. 

 Plant. 3. 747. 



Description.— jRoo^ of strong, hard, branching fibres. Leaves (6 inches 

 long) all radical, linear, glabrous, firm in their texture, edges revolute, 

 attenuated at the base, interspersed with scariose glabrous scales, which 

 become larger towards the innermost, these being terminated with a point 

 resembling the leaves, but shorter. Scape (9 inches high) erect, simple, 

 rather longer than the leaves, covered, especially at the base, with long 

 spreading colourless acute (not glandular) hairs, smoother upwards. 

 Raceme i\li inch long) spicate, the uppermost flowers expanding first, 

 each rising from the axil of a lanceolate green bractea, which is covered 

 with hairs similar to those on the scape. Pedicels hairy, half the length 

 of the primary bractese, and having secondary lateral bracteae. Caiyx 

 |-partite ; tube very hairy, having both pointed hairs and others which 

 are shorter and glandular ; segments connivent, blunt, having glandular 

 hairs only, the two outer the largest and broadest. Corolla purplish, 

 rose coloured, yellow in the throat, as well as the calyx covered on the 

 outside with glandular pubescence, the four larger segments nearly 

 equal, spreading, flat, channelled in the centre, and slightly crisped on 

 the edges, the two next the labellum rather the narrowest, and having 

 each one erect, ovate, entire tooth at its base, of similar colour with the 

 rest of the corolla, the two others green at their base on the outside, 

 and furrowed in the throat, the groove having prominent, erect, pubes- 

 cent edges ; labellum deflected from the inside of the calyx between the 

 lips, small, ovate, acute, yellow, with a purple crisped and crenate edge, 

 its appendices blunt spreading and much shorter than itself; tube pale 

 yellow, twisted, equal to the longest segments of the calyx, the whole of 

 the inside and the upper surface of the limb presenting, under the mi- 

 croscope, a beautiful crystalline appearance. Column linear, flat, equal in 

 length to the limb, dark red in front, yellow behind, glabrous, very ir. 

 ritable, bordered at its lower part. Anthers leaden-coloured, pollen gra- 

 nules lilac, minute, ovate. Stigma of dull green colour, oblong, glan- 

 dular surface crystalline. Germen ovate, bilocular, dissepiment imper- 

 fect above. Ovules very numerous, attached to a central receptacle, 

 awanting in the lower part of the dissepiment. 



This species is new in cultivation, and tlie flowers are larger than any in 

 our gardens. I owe to the late Mr Eraser, colonial botanist, a native 

 specimen collected at King George's Sound, on the south coast of New 

 Holland ; and, from seed picked off one sent at the same time to Mr 

 Macnab, the plant described was raised. It flowered in the greenhouse 

 of the Tloyal Botanic Garden in May, and will continue to bear flowers 

 during the early part of June. 



Symphitum Caucasicum. 



S. Caucasicum ; caule ramoso, inferne hirsuto, superne glutinoso ; foliis 

 ovato-lanceolatis, base attenuatis, semidecurrentibus, hirsutis; caly- 

 cibus obtusis. 

 Symphitum Caucasicum, Marsch. Bieb.l^l. Tauric. Caucas, 1. 128 — Spren- 

 gel, System. Veget. 1. 563. 

 Description — Stem (2 feet high) hirsute near the bottom, higher up pu- 

 bescent and viscous, slightly winged, flexuose, branched. Leaves ovato- 

 lanceolate, hirsute on both sides, but less harshly on the upper, and there 

 when young subviscid, half decurrent, the lower attenuated at the base, 

 the upper pair oblique, sessile and alternate. Spikes terminal, geminate, 

 many-flowered, secund and involute, common peduncle and pedicels 

 glanduloso-pubescent. Calyx angled, the angles and blunt teeth ciliated, 

 when in fruit distichous. Corolla at first red-purple, but loses this co- 

 lour as soon as it expands, and acquires a lively azure hue ; tube longer 

 than the calyx, sparingly and minutely pubescent on the outside, having
