sor Lindley only means the absence of the dilatation of the wing-like 

 edges towards their apex. Like Peristeiia petufnlaf its blossoms are 

 of short duration ; and I did not at any time find it to be perfumed. 

 We received the plant at the Botanic Garden from Mr Knight, King's 

 Road, Chelsea, in 1830. It flowered for the first time towards the end 

 of March 1840.

Description. — Stalk (3^ feet high) herbaceous, striated, erect, branched, 

 round, nearly glabrous above, below covered with soft, glandular, 

 waved, spreading, colourless hairs. Leaves (9 inches long, 4 broad) 

 smaller upwards, membranous, sinuato-pinnatifid, subglabrous on both 

 sides, much attenuated at the base, where they degenerate into the 

 appearance of a narrowly winged petiole ; semiamplexicaul and au- 

 ricled, the segments projecting forwards, much reduced below the 

 middle of the leaf, acute, intipo-lobate, the divisions mucronulate, 

 middle rib and veins very prominent behind, the secondary veins chan- 

 nelled in front. Peduncles terminal, elongated, swelling upwards, 

 hollow ; head of flowers at first nearly flat, afterwards elongated, and 

 densely subspicate ; general involucrum awanting ; partial involucrum 

 ovato-acuminate, 3-5 flowered, the scales ovato-lanceolate, spines- 

 cento-mucronate, the outer the shorter, and subcarinate at the apex. 

 Receptacle naked. Corolla pale lilac colour, funnel salver-shaped, 

 the tube longer than the involucre, hairy without, limb glabrous, seg- 

 ments linear-lanceolate. Stamens exsertefl, the filament neai'ly as 

 long as the limb of the corolla, distant, glabrous, of the same colour 

 as the corolla, but rather darker; the anthers of still darker colour, 

 and rather more red. Style twice as long as the corolla, straight, slen- 

 der, of the same colour as the filaments, slightly pubescent upwards ; 

 stigma bifid, revolute, Achenia dissimilar ; some abortive, clavate, 

 pubescent ; others fertile, obovate, plump, compressed, striated, gla- 

 brous and shining. Pappus deciduous ; in the abortive achenia double, 

 the exterior of one row of minute chafls, the interior hair-like, in many 

 rows, on the fertile achenia of the latter form only. 



This curious and ornamental stove-plant, native of Pemambuco, flowered 

 in the nursery of Mr Cunningham, Comelybank, in April 1840. f 

 could not learn when or by whom it was introduced. It is the only 

 known species of the genus, was discovered by Martius, and first, if I 

 am not mistaken, described in the fifth volume of Decandolle's Pro- 

 dromus.
