GENERA OF TAXACEX AND CONIFER. 23 
GLYPTOSTROBUS. 
A genus separated in 1847 by Endlicher from Tazrodium, and 
retained as separate by Parlatore, Eichler, and others. Bentham 
and Hooker, however, follow Brongniart and include it in 
Taxodiwm. It differs from that genus, however, in the tristichous 
or spiral, not distichous, arrangement of the deciduous foliage, and 
in the ovoid winged seed. The subglobose male flowers are on 
the ends of the lateral branches; anthers 3-4, globose. The female 
flowers are club-shaped, tapering at the base; the uppermost leaves 
appressed, imbricate, passing gradually into the bracts, which 
latter are almost entirely concrescent with the lobulate scale. 
The winged seed is usually described as erect, but it is certainly 
pendulous, being enclosed within a cavity at the upper part of 
the scale. 
The species requires further investigation in the fresh condition. 
The only recent species is a native of China ; but others existed in 
the Miocene period in Central Europe, Greenland, &c. 
CRYPTOMERIA. 
Founded by D. Don in 1839, this genus has met with general 
acceptance. The foliage is arranged spirally, heteromorphous ; 
the adult leaves are markedly “decurrent.” The male flowers 
are crowded in axillary spikes at the ends of the branches, with 
no intermediate leaves between the leaves and the anther-scales. 
Stamens spiral, connective pointed, with 3-5 globose anther- 
lobes; pollen-grains simple. The globular female cones are on 
the ends of the shoots, and ripen in the first year. The bracts 
are concrescent for the greater part of their length, leaving the 
pointed extremity free and recurved. The scales of the ripe cone 
spread horizontally at the base, and are wedge-shaped, obovate, 
thickened at the extremity and more or less deeply divided into 
sharply pointed lobes. Seeds 3-5 to each scale, erect, with a 
narrow wing. Cotyledons 2-3, linear or oblong, stomatiferous 
on the upper surface. Plumule with three longitudinal furrows. 
The cones frequently exhibit median prolification, owing to 
the recurrence of growth at the apex after the formation of the 
seed-scales. 
The only known species is Japanese.
