 large, thin-shelled nut, is the best known.

 broad, usually somewhat open head.

HIDAIGOA ("after the Mexican Hidalgo"). Syn., 

 Childsia. OoHip6sit(P. This includes a tender her- 

 baceous vine, allied to Dahlia, with scarlet fls. about 

 2}4in. across, introduced in 1899 by John Lewis Childs, 

 under the name of Childsia Wercklri, or "Treasure 

 Vine." Hidalgoa is closely allied to Dahlia and Coreop- 

 sis, but differs from both in the large, fertile akene of 

 the rays and in the sterile disc-fls., the styles of which 

 are entire or very shortly 2-lobed. Only 2 species were 

 hitherto recognized, both from Central America. From 

 these H. Wercktei differs in its more compound Ivs. 

 and much larger heads. Suitable for cool, shady ver- 

 andas. 



Wfircklei, Hook. (ChUdsia W(reklei, i. L. Childs). 

 Tall, woody at base, much branched, climbing by peti- 

 oles : Ivs. opposite, pinnately ternatisect, \yi-2%\n. 

 long, 2 in. wide, the teeth tipped reddish brown; petiole 

 IV2-2 in. long, coiled at base: peduncle axillary, as long 

 as the Ivs., 1-fld.: rays about 10. Costa Rica. B.M.
