V^ar. indent^ta {Z. indcHlata, Sturt.). Dent Corn. 

 Fiff. 2780. Piute VII. A group recognized by the pres- 

 ence of corneous endosperm at tbe sides of the kernel, 



the starchy endosperm fxtending to the summit. By the 

 drying and shrinkage of 

 the starchy matter the 

 summit of tbe kernel is 

 drawn in or togethi-r, and 

 indented in various furnis. 

 In diti'ereut varieties the 

 corneous endosperm varies 

 in height au<l thickness, 

 thus detei'niining the char- 

 acter of the indented sur- 

 face.

 This grou]) is at once recog- 

 nized by the absence of cor- 

 neous endosperm. Through 

 the uniformity of the shrink- 

 age in ripening there is usu- 

 ally no indentation, yet in 

 soine varieties an indentatinn 

 may more or less frequently 

 appear, l")ut splitting the kei-- 

 nel infallibly determines tbe 

 class.

 VII. A well-defined group 

 characterized by the translu- 

 cent, horny appearance of the 

 kernels and their more 

 wrinkled, or shriveled condition. 



Var. am^lea-saccharata {Z. aiuf/lea-sarrha- 

 r(if a, Stuvt.). Stauchy-isweet (.'okn. This 

 group is founded upon three varieties found 

 in the San Pedro Indian cnllectiou of Dr. 

 Palmer and sent in 1880. The extfrnal ap- 

 pearance of the kernel is that of a sweet, but 

 examination shows that the lower half of the 

 kernel is starchy, the upper half horny and 

 translucent. Tliese varieties all had a white 

 cob, the kernels deeper than broad.

ZELKOVA (after the verna- 

 cular name Zelkoua in Crete, or 



Selkwa in the Caucasus). Syn., Ahelicea. UrticcLcew. 

 Ornamental deciduous trees, with alternate, short-peti- 

 oled, toothed leaves and insignificant tlowers in axillary 

 clusters or solitary, followed by small drupe-like fruits. 

 Z. acuminata is hardy north and Z. crenata hardy as 

 far north as Mass., at least in sheltered positions. Tbe 

 Zelkovas, particularly Z. acuminata, are handsome 

 trees of graceful habit, much resembling 

 a small-leaved elm tree. They seem not 

 to be very particular as to soil and posi- 

 tion. Prop, by seeds sown soon after 

 ripening; also by layers and by grafting on 

 Uiraus. Four species are known, natives 

 of Crete, the Caucasus and E. Asia. 

 They are allied to Celtis and Aphananthe 

 and are chiefly distinguished by the con- 

 nate sepals. From the elms, which they 

 much resemble in foliage, they are easily 

 distinguished by the drupe - like fruits.
