Dr Graham's Description of New or Rare Plants. 171 



in July 1829, and being kindly sent by Colonel Lindesay, were received 

 at the Botanic Garden, Edinburgh, twelve months afterwards. Several 

 plants lowered freely in the greenhouse in May 1832. They form a 

 handsome addition to the species previously in cultivation. There is 

 reason to believe that the seeds will ripen. 



Rulingia corylifolia. 



R. corylifolia ; foliis ovato-deltoideia, jsubcordatis, basi lobatis supra his- 

 pidis, subtus hirsuto-tomentosis ; stipulis ovato acuminatis ; corymbis 

 oppositifoliis ; JSlamentis antheriferis simplicibus, sterilibus ovato-lan- 

 ceolatis alternantibus. 

 Desceiptiok Shmb branched from the base of the stem, branches slight- 

 ly flexuose, tomentoso-villous, and slightly viscid. Leaves (2| inches 

 long, 2 inches broad) ovato-deltoid, slightly cordate, slightly lobed at the 

 base, serrato-crenate, rugose, pubescent on both sides, but much more 

 considerably behind, where also they are paler, bright green above, and, 

 when fading, becoming red, being very prominent behind ; petioles slight- 

 ly channelled above, villous, much shorter than the leaves, bistipulate. 

 Stipula opposite, distinct from the petiole, ovate, acuminate, villous, and 

 with long ciliae. Corymbs collected near the apices of the branches, densely 

 covered with white hairs in its primary and subsequent divisions, each 

 division having on the outside a lanceolate bractea. Flowers pedicellate, 

 white. Calyx 5-phyllous ; phylla cordate, villous both within and with- 

 out, but much more harshly without, somewhat reflected in their sides, and 

 forming a prominent edge where they meet each other. Petals pubescent, 

 much smaller than the calyx segments, concave, gibbous at their base, 

 their sides formed into two blunt parallel wings, which project towards 

 the axis of the flower, apex extended into a blunt linear appendage, at 

 first curved towards the axis, but afterwards bent back, and passing out 

 between the segments of the calyx. Stamens 5 (perfect), immediately 

 within the petals, and alternating with the segments of the calyx, shorter 

 than the petals, and included witnin their folds, alternating on the same 

 urceolate border with, and somewhat shorter than, ovato-lanceolate scales 

 (abortive stamens), which are hairy on the outside, smooth within ; fila- 

 ments glabrous ; anthers short, bilocular, bursting along the sides. Pol- 

 len yellow, granules round. Stigmata cohering to each other, small, ca- 

 pitate, colourless, shining. Styles 5, glabrous, in contact in the centre of 

 the flower, scarcely longer than the stamens. Germen 5-lobed ; in its 

 early stages lobes conical and a Httle rough, afterwards rounded, green, 

 depressed in the centre, and densely covered with stellate pubescence, 

 5-locular, dissepiments from the edges of the valves, their two layers 

 afterwards separating. Ovules two in each loculament, with a central 

 ridge of the valve between them, both attached to the central column 

 below its middle. Pubescence every where on the plant stellate, except 

 from abortion, when, as on the upper surface of the leaves, it often ap- 

 pears single. 

 This plant was received last year by Mr Neill at Canonmills, and in the 

 Botanic Garden, Edinburgh, from Mr Knight on the King's Road ; and 

 both with Mr Neill and us, it flowered freely in the greenhouse in May 

 last. I am indebted to my acute friend Dr Hooker for many important 

 references regarding this genus and its allies, which led me to investi- 

 gate its structure much more closely than I otherwise would, and pre- 

 vented my committing some mistakes. 



Stylidium hirsutum. 



S. hirsutum; scapo hirsuto villis acutis; racemo subsimplici; caJycis 

 labia (§-) partita; capsula ventricosa ovata; foliis linearibus, basi at- 

 tenuatis, marginc parum recurvis, squamis scariosis distinguantibus 

 interioribusque acuminatis.— J?r.
