and September. The flowers are showy, pro- 

 duced in umbels ; the color of rays and disk is 

 uniform bright orange. H. pumilum is the 

 smallest and perhaps the poorest of the genus, 

 none of which take the place of the Helianthus. 

 Helianthus rigidus, generally known as Har- 

 paltum rigidum, is a very striking early species, 

 with large, brilliant, dark-yellow flowers. It is the 

 lowest-growing of the genus, not exceeding four 

 feet in height. Its habit is to run much at the 

 root, and therefore it soon becomes troublesome 

 in the flower-border. But it should not be neg- 

 lected on this account, and a place should be 

 found for it where it will have room to make its 

 bright midsummer display. The Echinacea, or 

 cone-flower, on account of the large heads of 

 purple produced by E. purpurea and E. angus- 

 lifolia, is worth growing. Coreopsis lanceolata 

 is the finest of its genus, although C. grandi- 

 flora, C. pubescens, and C. auriculata are not 

 unlike it. C. verticillata is a small and pretty 

 species, with delicate foliage and numerous small 

 yellow flowers. C. prcecox is not worth growing, 

 notwithstanding it is described as " cette char- 

 mante espece " in the suave French catalogues. 

 Other fine Heltanthece are : Helianthus doroni- 

 coides, H. strumosits, H. orgyalis, H. gtganteus, 

 H. tuberosus, and H. Maximiliani ; the last
