The genus Hidalgoa is closely allied to Dahlia and 
Coreopsis, but differs from both in habit, in the large fertile 
achene of the ray-flowers, and in the sterile disk-flowers, 
the styles of which are entire or veryshortly two-lobed. Only 
two species have hitherto been recognized, the H. ternata, 
Llav. & Lex. of Mexico and Central America, and a closely 
allied one (or possibly a variety) from Guayaquil. From 
both of these H. Wercklei differs in its more compound 
leaves and much larger heads, the ray-flowers of which are 
bright scarlet... 
According to Mr. John Lewis Childs, of Floral Park, 
New York, who published it as Childsia Wercklei, with a 
coloured illustration, on the back of his sale-catalogue, cited 
above, it is a native of Costa Rica, where it was discovered 
on a mountain, by Mr. Carlo Werckle, in 1598. <A plant 
was sent to the Royal Gardens, Kew, by Mr. J. L 
Childs, which flowered in a greenhouse in July, 1899. 
Descr.—A tall, suffruticose, much-branched herb, climb- 
ing by means of the petioles, which twist round objects of 
support, glabrous, except for a slight pubescence on the 
NovemBer Ist, 1899.
