364 Dr Graham's Description of' New or Bare Plants. 



brous. Raceme terminal, lax ; pedieels resembling the extremity of the 

 scape, solitary from the axils of the bracteae, and frequently bracteolate, 

 pubescent on their upper side, pubescence glandular. Calyx segments 

 subulate, unequal, glabrous. Corolla small, rose-coloured, tube longer 

 than the calyx, twisted ; faux very oblique, crowned with a few glandu- 

 lar hairs ; limb glabrous on the inside, sparingly covered with glandular 

 pubescence on the out, segments ovate, bkmt ;' labellum oblongo-ovate, 

 inappendiculate. Germen green, turbinate, with five gibbosities at the 

 top from which the calyx-segments spring. Column flat, much longer 

 than the corolla, tapering below and above broadest where first deflected 

 over the labellum, and at this point lilac, below white, above rose-co- 

 loured, everywhere glabrous, dilated fleshy and reticulated at the sum- 

 mit. Anthers small, yellow, glabrous. Stigma prominent, green, pubes- 

 cent. 

 f This plant, less ornamental than perhaps any of the species hitherto intro- 

 duced into cultivation, but still interesting, was raised, from seed from 

 King George's Sound, at the Caledonian Horticultural Society's Garden, 

 last year. One of the seedlings, communicated to Mr Neill, Canonmills, 

 came into flower in the beginning of September 1832, in consequence of 

 the judicious treatment it received. We have raised it at the Botanic 

 Garden this season, and many of the plants are pushing up their scapes, 

 but the flowers will not be expanded for some time. 



Tropaeolum pentaphyllum. 



T. pentaphyllum ; foliis digitato-quinatis ; foliolis ovalibus, integerrimis, 

 petiolatis ; petalis duobus, subrotundis, subsessilibus, calyce multo bre- 

 vioribus; calcare recto, apice ovato carnoso ascendent!.

 Description — Root tuberous, large, oblong. Stem slender, greatly elon- 

 gated, slightly twisted, round, glabrous, coloured, branched. Leaves 

 (about 2 inches across) petioled, digitate, of 6 oblong entire petiolate 

 soft glabrous spreading leaflets. Common petiole (2 inches long) twisted 

 in form of a tendril, and forming the chief support of the stem, as well as 

 the partial petioles and the veins of the leaf purple and glabrous : partial 

 petioles bordered by the decurrent leaflets. Peduncles (4 inches long) so- 

 litary, axillary, longer than the leaves, purple, glabrous, thickening up- 

 wards, pendulous. Calyx (1^ inch long) persisting; spur horizontal, 

 fleshy, dull purple on the outside, yellow within, nectariferous, conical, 

 till towards its apex, when it is contracted, thinner, and somewhat shri- 

 velled, the apex being ovato-acute, fleshy and erect; limb (74 lines across) 

 5-parted, green, brighter and spotted or streaked with deep purple with- 

 in, segments ovato-acute, the uppermost the narrowest, the two next to 

 it the broadest. Petals 2, small, subrotund, subunguiculate, reflected, 

 bright vermilion-coloured, inserted into the throat of the calyx on each 

 side of the upper segment. Stamens 8, longer than the calyx segments ; 

 filaments subulate, declined, closely streaked or spotted with purple, in 

 the bud erect, turned out between the calyx segments after the pollen 

 is shed ; anthers four-sided, oblong, truncated above and below, green ; 

 pollen green. Germen yellow, glabrous. Style yellow, 3-sided, shorter 

 than the stamens. Stigmata 3, acute, diverging. Fruit 3-coccous, gla- 

 brous, even. 

 Mr Neill received at his garden at Canonmills a tuber gathered by Mr 

 Tweedie in 1829. It pushed out some feeble shoots in 1830, and also 

 last year, and is now growing most vigorously, settling a question of 

 which De ClandoUe was doubtful, — that the species is perennial. A 

 cutting taken from it, flowered in the greenhouse for the first time, and 

 most freely, during June and July 1832, and will probably ripen its 

 seeds. From Mr Tweedie I have excellent native specimens, gathered 

 in hedges near Buenos Ayres. Its taste is very similar to that of TrO' 

 paolum majusi but less pungent, and less agreeable.
