SUPPLEMENT. 



from 5 to 7, short, obtuse ; the mar- 

 gins revolute and occasionally toothed. 

 Petioles very short, slightly chan- 

 neled above, sheathing at the base. 

 Stipules adherent ; the free apices 

 subulate, hairy, green, shorter than 

 the adherent portion. Flowers ter- 

 minal, solitary; when in the bud 

 state, exactly like those of liosa. Pe- 

 duncles extremely short, cylindrical, 

 thickened towards the apex, copiously 

 downy and glandular, and furnished 

 at the base with a single, linear, acu- 

 minate, channeled, glandular bractea. 

 Calyx turbinate, hollow, copiously downy and glandular ; tube glabrous, 

 shining and green within ; limb o-parted, spreading ; segments ovate, acumi- 

 nate, entire. Petals 5, obovate, double the length of the calycine segments, 

 of a rich lilac. Stamens 72, disposed in many series. Filaments capillary, 

 glabrous, white, pink at the base. Anthers cordate, yellow, bilocular ; the 

 cells parallel and opening lengthwise. Ovaria 14, free, arising fron) the 

 centre of the torus, which is seated at the bottom of the calyx ; oblong, 

 clavate, copiously silky. Styles continuous, short. Stigmas terminal, 

 simple, yellow, minutely papillose. Achenia about 8, turbinate, silky, 

 crowned by the persistent feathery styles, which are Uin. long. ' We have 

 seldom,' Professor Don remarks, ' had an opportunity of laying before our 

 readers a subject of equal interest and beauty with the present, which is not 

 only a new species, but a new genus, to our gardens. It was raised by our 

 zealous friend Mr. Thomas Blair, gardener to Mr. Clay at Stamford Hill, 

 from seeds picked from a specimen collected by Captain Colquhoun in the 

 uplands of Mexico. It promises to be sufficiently hardy to endure our 

 winters in the open air ; and, as it is an evergreen shrub, with a peculiar 

 habit, and large showy blossoms resembling a small rose, it must be regarded 

 as the most valuable addition made to our gardens for some years past.' 

 The genus was originally founded by Professor Don, in the Liniucan Trans- 

 actions, vol. xiv., on another species, collected in the same country by 

 Sesse and Mocino, and which is distinguished from the present one by its 

 tripartite leaves, with entire lobes. Professor Don considers the genus to 

 be exactly intermediate between Dryas and Purshiff, differing Irom the 

 former in the quinary aiTpngement of the floral envelopes and definite 

 ovaria ; and from the latter, in the more numerous achenia, crowned by the 

 persistent feathery styles."
