seeds, given him by Mr. Burst. It belongs to the subdivi- 
sion Evnetenten, Div. Garttarpie®, Subtribe Hexentia, of 
the Senecronipez of De CanpoxE; a groupe which includes 
genera not easily distinguished by tangible characters ; but 
I think our plant may be referred, without any doubt, to the 
Genus Hymenoxys of Cassini, although the species hitherto 
described of it are natives only of Mexico, Peru, and Bue- 
nos Ayres. No doubt the species will prove a perfectly 
hardy annual; though Mr. Moore had the precaution to 
raise the present plants in a pot for the sake of affording 
them shelter. It flowered in September, 1839. 
Descr. Root small, annual, fibrous. Stem a foot high, 
erect, slender, glabrous, branched. Leaves opposite, eX- 
cept the upper ones, two inches or more long, deeply cut 
in a pinnatifid manner into from five to seven distant, narrow, 
linear, entire lobes, quite glabrous, flaccid : uppermost ones 
linear and entire. Peduncles terminal, elongated, slender, 
single-flowered. Involucre hemispherical, of about ten to 
twelve lanceolate, acute, downy scales, in one series, OF only 
slightly imbricated at the base. Corollas yellow. 
of the ray ligulate, one to each scale of the involucre, thre 
toothed at the apex. Achenium slender, between cyH! 
drical and fusiform, downy with five to six rather small, 
subulate, serrated scales. Florets of the disk tubular: the 
tube glandular below, enlarged upwards, five - tooth J; 
the teeth clothed with thickened hairs near the points. 
Branches of the style obtuse, tufted at the apex. Achenwum 
(sterile ?) similar to that of the ray, the scales of the papp¥S 
larger. Receptacle large, conical, pitted, slightly hairy.
