EL^EAGNACELE 



465 



1'85 cm. long, 5-7 mm. wide; petioles semiterete, slightly grooved 

 above, tapering slightly upwards, pale green, 4-9 mm. long. 



Stem erect, terete, densely covered with stellate or radiate scales, 

 ultimately shrubby ; 1st internode 

 6-9 '5 mm. long. 



Leaves simple, entire, cauline, 

 alternate (first two opposite or nearly 

 so), exstipulate, petiolate, alternately 

 and ascendingly penninerved, densely 

 covered beneath with stellate scales, 

 and on the upper side at least in 

 the seedling; petioles short, semi- 

 terete, slightly grooved or merely 

 flattened above, densely stellate-scaly 

 like the leaves. 



Xos. 1-4. Lanceolate-oblong, 

 acute or obtuse, alternately and 

 ascendingly penninerved, with few 

 and indistinctly visible nerves in- 

 curving and uniting in a single intra- 

 marginal wavy line. 



FIG. 634. Elceagnus angustifolia 

 var. microcarpa. Nat. size. 



The seedling of Elseagnus hortensis, M. ., closely resembles 

 the preceding. 



Hippophae rhamnoides, L. 



Fruit enclosed in the baccate perianth ; pericarp thin, mem- 

 branous, pale-coloured, traversed along two sides with a thickened 

 yellow nerve or ridge uniting beneath the persistent style and also 

 at the base of the seed, one-seeded, indehiscent. The baccate peri- 

 anth becomes enlarged at the base, and globular, ultimately fleshy 5 

 pulpy or almost deliquescent internally. 



Seed obovoid, marked on two sides with a vertical depressed 

 line caused by the ridges on the pericarp, slightly unequal at the 

 base ; testa very much thickened and hardened, shining black, 

 smooth ; hilum basal between the unequal lobes of the emarginate 

 base. 



Endosperm in the mature seed forming a very thin layer on the 

 inner surface of the testa, except at the base where it forms a 

 thick sheath round the radicle. 



Embryo straight, large, subobovoid, fleshy, occupying almost the 

 whole of the seed ; cotyledons plano-convex, closely occupving the
