nous pericarp, surmounted by the remains of the style. It contains 
a single seed, within whose very thin coats lies a large fleshy embryo, 
almost or wholly exalbuminous, with its radicle inferior. 
The genus H@agnus consists of trees or shrubs from Central Asia, 
the South of Europe, and North America. All their organs are 
covered with peltate hairs, scurfy or stellate. Their leaves are alter- 
nate exstipulate simple entire. Their flowers are axillary, solitary 
paired or grouped in little 3-flowered cymes or short leafy racemes. 
Some twenty species are admitted.’ 
The genera Shepherdia’ and Hippophae (Fr., Argoussier) complete this 
series. The former (figs. 285-288), has dicecious flowers (figs. 287, 
Shepherdia canadensis.

perianth, and eight glands superposed in pairs to the sepals and 
inserted in the throat. The gynzeceum occupies the bottom of the 
flower ; here too it becomes an achene around which the receptacle 
forms a drupaceous indusium. The male flowers (figs. 285, 286), 
have a much shallower cupuliform receptacle. On its edges are in- 
serted eight free stamens, four superposed to the sepals, and four 
alternate with them. Each has an introrse anther and a slender 
filament inserted outside the circle of eight glands, which are as in 
the female flower superposed to the calyx-lobes. Only two species 
of Shepherdia’ are known, shrubs from North America with opposite
