Dr Graham's List of' Rare Plants. 177 



Graham of his Majesty's Packet Service ; but other specimens, which are 

 extremely similar, were in the collection before, though it is not known 

 from whence obtained. These differ from the plant described, only in 

 having the back of the leaf more reticulated, the anthers paler, and the 

 shorter stamens equal in length to the styles. 



Passiflora alata, var. pedunculata. 



I have already noticed three varieties of this beautiful species cultivated 

 in the Botanic Garden at Edinburgh. The present was raised from seed 

 brought by Captain Graham of his Majesty's Packet Service from Rio 

 de Janeiro in 1823. It is as handsome as the finest of these, and in fo- 

 liage very much resembles the var. insignis. It is, however, easily dis- 

 tinguished from all the others, by the peduncle being equal in length to 

 the petiole ; by the bractese being very large ; by the stipulse having 

 one or two teeth on one side ; by the nectaries being rather shorter, and 

 opening wider. 



Penaea imbricata. 



P. imbricala ; foliis rhombeo-ovatis, acutis, integerrimis, quadrifariam im- 

 bricatis vel patulis ;.ramis tetragonis, decussatis, floribus terminalibus ; 

 bracteis paucis, nudis, coloratis, sagittatis, folio minoribus ; laciniis co- 

 rollse obtusis, medio plicatis. 



Description. — Shrub erect, bark brown and cracked; brandies numerous, 

 decussating, ascending, four-sided. Leaves sessile, rhomboid-ovate, co- 

 riaceous, somewhat pointed, decussating, generally spreading on the 

 branches, imbricated towards the flowers, naked on the back, middle rib 

 distinct, with a few obscure lateral veins. Bractece few, sagittate, with- 

 out cilise, coloured. Calyx diphyllous, segments linear, coloured, alter- 

 nating with two hastate bractese nearly on the same plane. Corolla rose 

 coloured, tubular, tube furrowed, inflated at its base, tapering somewhat 

 to the throat, less than double the length of the calyx ; limb 4-parted, 

 segments rounded, with a slight point in the centre, folded back in the 

 middle, about half the length of the tube, and slightly contorted. Sta- 

 mens 4, alternating with the segments of the corolla, and attached to 

 the throat ; filaments subulate, coloured ; anthers large, cordate, as long 

 as the filaments ; pollen yellow. Germen 4-lobed, 4-celled, pointed ; style 

 terminal, 4.sided; stigma cajtitate, 4-cornered. 



liaised from Cape cf Good Hope seeds, kindly communicated to the Royal 

 Botanic Garden, Edinburgh, by Mr Alton, in 1823, and kept in the 

 greenhouse. 



Primula longiflora. 



Psidimn chinen.se. 



StercuHa Balanghas. 



Strophanthus divergens. 



S. divergens ; frutex erectus ; ramis oppositis, patentissimis, foliis oppositis, 

 lanceolato-oblongis, nitidis, stipulis parvulis, acuminatis, intra axillari- 

 bus, pedunculis terminalibus, dichotomis, segmentis calycinis bracteis- 

 que erectis, subulatis. 



S. dichotomus ; /3 chinensis, Bot. Reg. t. 469. 



Description. — With us a shrub of nearly 2 feet high, and probably ne- 

 ver free growing, erect, and certainly in no degree sarmentose or climb- 

 ing. Branches numerous, and spreading at right angles. Bark brown, 

 and thickly sprinkled with light coloured warts. Leaves crowded on 

 the extremities of the branches, suberect, on short petioles, opposite, 

 lanceolate -oblong, or sometimes inclining to ovate, shining, having a 

 strong middle rib, and strong nearly transverse veins uniting in arches 

 near the edges of the leaf, mucro very small. Stipulce very small, 

 pointed, one at each side of the axils of the leaves. Pedmicles termi- 

 nal, once, twice, or rarely oftener dichotomous : often three buds form
