ORDER SUPERFLUA. 171 



of the former Asters, with corymbose flowers, form, 

 in fact, a part of that division, though they have not 

 the characteristic yellow flowers. In these the calyx 

 is closely imbricated, and no part of it spreading ; 

 the receptacle naked ; the pappus scabrous (or some- 

 what subdivided) ; and, in nearly all the native species 

 of our subgenus, furnished with a short, exterior chaffy 

 pappus. 



The smallness of the flowers at once distinguish 

 the Solidago's, or Golden-rods, from the Inulas ; 

 these have also small imbricated calyces, with the 

 scales very generally connivent. The florets of the 

 ray are only about 5, and yellow. The receptacle 

 naked ; and the pappus simple and scabrous. The 

 genus is naturally divisible into 2 sections ; in one of 

 which the flowers are disposed in terminal, secund 

 (or 1 -sided) racemes ; in the other, they form irregu- 

 lar, and smaller clusters. 



One of our too common weeds in dry pastures, is 

 the White- weed, or Ox-eye Daisy, of the genus 

 Chrysanthemum. This plant has an hemispherical, 

 imbricated calyx, the close scales of which have 

 membranaceous margins. The receptacle is naked ; 

 and there is no pappus. Our only species wild, is 

 the C. leucanthemum, which, for a great part of the 

 year, continues to send up simple stems, clothed with 

 amplexicaule, lanceolate, serrated leaves, more deeply 

 cleft at the base, and terminating in large, Daisy-like, 

 white rayed flowers. Of the same genus are those 

 beautiful and numerous varieties of the C. Indicum, 

 so commonly cultivated, and so grateful in appearance, 

 blooming to the very approach of winter, when all 

 other flowers have disappeared ; but these, of so many 

 fine colors, introduced from China, are always double, 

 or rather monstrous, having the perfect discal florets 

 all transformed into ligulate or radial ones, and pro-
