 A.F. 14:339. Next to Pecan the best as 

 a fruit tree, especially for the northern 

 states, where Pecan is not quite hardy. 

 Several named varieties are in trade, of 

 which probably var. Hales i, Hort., with 

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

 An ornamental, often very picturesque 

 tree; the stout branches forming a rather 

 broad, usually somewhat open head.

 H. ovata: fr. smaller : Ifts. 3-5, oblorig-lanceo-

HIDALGOA ("after the Mexican Hidalgo"). Syn. 

 Chlldsia. Compdsitce. This includes a tender hex 

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

 2% in. across, introduced in 1899 by John Lewis Child? 

 under the name of Childsia Wercklei, or "Treasur 

 Vine." Hidalgoa is closely allied to Dahlia and Coreop 

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

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

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

 hitherto recognized, both from Central America. Fron 

 these H. Wercklei differs in its more compound Ivs 

 and much larger heads. Suitable for cool, shady ver 

 andas. 



Wercklei, Hook. (Childsia Wercklei, J. L. Childs) 

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

 oles : Ivs. opposite, pinnately ternatisect, l%-2>2 in 

 long, 2 in. wide, the teeth tipped reddish brown: petioli 

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

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

the eastern states. Lvs. often toothed, but never deeply 

 lobed : heads usually small, loosely paniculate or cy- 

 mose, rarely solitary: rays truncate, 5-toothed at the 

 apex : seeds angular. The genus passes into Crepis.
