186 Dr Graham's List of Rare Plants. 



Crotalaria dichotoma. 



C dichotoma ; Fruticosa, diffusa ; foliis ternatis, foliolis cuneato-ellipticis, 

 pilosiusculis, mucronatis ; stipulis subulatis, reflexis, persistentibus ; ra- 

 cemis subcapitatis, oppositifoliis. 



Description — Siem weak, round. Branches long, straggling, pubes- 

 cent, and slightly furrowed towards the top, subdichotomous, one of 

 the limbs being generally a little thicker than the other. Leaves ter- 

 nate, leaflets elliptical, mucronate, wedge-shaped at the base, rather 

 longer than the petiole, and supported on very short, equal, partial 

 footstalks, soft, covered with minute pubescence, very indistinct on the 

 upper surface, bright green, and becoming mottled in fading, middle 

 rib strong, petioles half an inch long, furrowed, spreading at right angles 

 to the branch. Racemes opposite to the leaves, subtriquetrous, occa- 

 sionally one flower in the middle, the rest crowded near the top. Brac- 

 tecB like the stipulae, but less frequently reflected. Calyx bilabiate, hairy, 

 segments pointed, green ; upper lip 2-parted, segments diverging ; lower 

 lip 3-parted, segments parallel, closely applied to the carina. Corolla 

 yellow ; veonllum rounded, reflexed, streaked with brown on the back, 

 claw furrowed and hairy on its lower side ; alee involute, shorter than 

 the vexillum ; carina pointed, equal in length to the alse, split at its base, 

 its lower edge forming nearly a right angle. Stamens monadelpheus ; 

 filaments very slender, five nearly as long as the style, supporting small 

 round (abortive ?) anthers^ five shorter having oblong anthers of deeper 

 yellow colour. German pubescent, flattened ; style turgid at the base, 

 above which it is bent nearly to a right angle, filiform, hairy, persisting ; 

 stigma small and pointed. Legumen covered with small adpressed hairs, 

 inflated, nearly cylindrical, slightly furrowed above. Seeds numerous 

 (about 14), kidney-shaped, and arranged in two rows, at least when 

 young. 



The seeds of this plant were brought to the Botanic Garden from Mexico 

 in 1824 by Dr Mair, and the plants have flowered in our stove during 

 the last two years. 



Cypripedium insigne. 



Dianthus fruticosus. 



Flowered fireely in the open border. 



Eucalyptus cordata, and E. perfoliata. 



These two plants have been covered with buds on the open wall during se- 

 veral weeks, but have not expanded any flowers. They have not, how- 

 ever, been in the least injured by the late severe frosts ; and the last has 

 been out of doors for three years. 



Lantana hirta. 



L. hirta ; inerma ; foliis ovato-lanceolatis, acuminatis, rugosis, supra hirtis, 

 subtus nitidis, serrato-crenatis, basi cuneatis integerrimis ; pedunculis 

 axillaribus, foliis brevioribus ; bracteis ovatis, acuminatis. 



Description Shrub erect ; branches 4-sided, brown, slightly hairy, 



angles blunt ; hairs most conspicuous and harsh, and suberect on the 

 young shoots. Leaves petioled, opposite and decussating, wrinkled, 

 hispid above, shining, and destitute of all hairs below, excepting on 

 the veins, where there are a few, acuminate, wedge-shaped, and quite 

 entire at the base, the rest serrato-crenate, veins prominent behind ; 

 petioles short. Flowers capitate. BractecB ovate, acuminate, smaller 

 inwards, hairy. Calyx sessile in the axil of the bractea, campanulate, bi- 

 labiate, the Hps placed laterally, hairy, small, greenish-white. Corolla 

 white ; tube equal in length to the bractea, slightly curved upwards, di- 

 lated in the centre, about twice the length of the limb, hairy especially 

 on the outside and in the throat, quite smooth within the calyx, hairs sub- 

 erect ; limb 4-parted, lateral segments blunt and smallest, lower segment 

 subrotund, upper retuse, smooth above, hairy below. Stamens inserted
