464 OX SEEDLINGS 



They differ from those of Hippophae rhamnoides in being more 

 deeply auricled at the base, but more especially in having 

 semiterete petioles 4-9 mm. long. The first four leaves are 

 lanceolate-oblong, penninerved and covered with stellate 

 scales. The first two are opposite, the rest alternate ; this 

 is also the case sometimes with Elseagnus hortensis, where 

 the first two are lanceolate ; the cotyledons exhibit an in- 

 distinct midrib, but are otherwise similar to those of the last- 

 named species, except that the petioles are shorter. 



Elseagnus longipes, A. Gray. 



Fruit an achene, enclosed in the fleshy or baccate perianth, 

 furnished with stellate scales that do not cover the whole sur- 

 face, yellow or nearly scarlet when mature ; middle layer of perianth 

 juicy or pulpy; inner layer hardened or bony and strengthened 

 with numerous longitudinal, strong, thickened ridges, and covered 

 on the inner face with a dense interlacing layer of tough cottony 

 hairs ; pericarp thin, membranous, tipped with the remains of the 

 style, pale-coloured. 



Seed ellipsoid, rather narrow, conforming to the interior of the 

 ovary, which again conforms to the interior of the calyx-tube ; testa 

 thin, membranous, whitish ; raphe passing along the whole length 

 of tbe seed and forming a conspicuous ridge ; funicle short ; chalaza 

 apical and superior, conspicuous ; hilum and micropyle basal, inferior, 

 contiguous. 



Endosperm absent. 



Embryo straight, large and occupying the whole interior of the 

 seed, colourless ; cotyledons lanceolate or oblong, obtuse, rather 

 deeply auricled at the base, otherwise entire, plano-convex and each 

 occupying half of the seed, lying with their edges to the raphe (in 

 all tbe specimens examined) ; radicle oblong or ellipsoid, obtuse, 

 about half its length protruded beyond the auricles of the cotyledons 

 and much shorter than the latter, occupying the narrow base of the 

 seed. 



Elseagnus angnstifolia, L., var. microcarpa (fig. 634). 



Hypocotyl erect, terete, glabrous, rarely with a few stellate 

 scales, pale green, 3-3'5 cm. above tbe soil. 



Cotyledons oblong, obtuse, entire at tbe apex and rounded, deeply 

 auricled at tbe base, thick, fleshy, with indiscernible venation, some- 

 what shining, pale opaque green above, bright green beneath, 

 mostly glabrous or with stellate scales on the petioles ; lamina 1-
