 a fruit tree, especially for the northern 

 states, where Pecan is not quite hardy. 

 Several named varieties are in trade, of 

 which probably var, Balesi, 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,

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

 CMldsia. Compdsitw. This includes a tender her- 

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

 2K in, across, introduced in 1899 by John Lewis Childs, 

 under the name of Childsia Wercklei, 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 di8c-fls.,the styles of which 

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

 hitherto recognized, both from Central America. From 

 these n. Wercklei differs in its more compound Ivs. 

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

 andas. 



Wercklei, Hook. {Childsia Wh-cklei, J. L. Childs). 

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

 oles : Ivs, opposite, pinnately ternatisect, 1H-2H in, 

 long, 2 in, wide, the teeth tipped reddish brown : petiole 

 lK-2 in, long, coiled at base; peduncle axillary, as long 

 as the lvs„ 1-Hd,; rays about 10, Costa Rica, B.M,
