294 RETINISPORA ; OR 



GcH. RETINISPORA. SieboUL 



Flowers, raoncccious, or male and female on the same plant, 

 but separate, and terminal, the males cylindrical, female soli- 

 tary, very small, and on the same branchlets as the males. 



Cones, very small, globular, ligneous, and solitary. 



Scales, ovate, in alternate cross pairs, ten or twelve in num- 

 ber, wedge-shaped at the base, peltated on the top, and woody. 



Seeds, in a channel, coated with resin, and two at the base of 

 each scale, with a membranaceovis wing, marked with resinous 

 bands. 



Leaves, persistent, in threes, or opposite pairs, linear, or 

 scale-formed, and mostly spreading. 



Seed-leaves, in twos. 



Name derived from ' rhetine,' resin, and ' spore,' seed, — the 

 seeds being coated with resin. 



All evergreen trees or shrubs, natives of Japan. 



No. 1. RETINISPORA ERicoiDES, Zucc, the Heath-like 



Retinispora. 



Syn. Chamsecyparis ericoides, Carriere. 



„ Widdringtonia ericoides. Knight. 



Leaves, in threes, but sometimes in opposite pairs, spread out 

 or bent downwards, linear, flat, a quarter of an inch long, fre- 

 quently slightly convex, and marked on the upper side with 

 two little glaucous bands, tapering regularly to the point, de- 

 current at the base, and mucronate. 



This kind forms a regular, conical, compact, pyramidal bush, 

 from four to six feet high, with numerous horizontal branchlets, 

 which are very slender and compact. It is cultivated by the 

 Japanese in pots, under the name of ' Nezu ' (dwarf). 



It is very near Retinispora squarrosa, and probably not dif- 

 ferent from what Dr. Siebold calls Retinispora squarrosa lep- 

 toclada, or the slender variety. It, however, is very much more 

 compact, and dwarfer than Retinispora squarrosa. 



It is tolerably hardy.
