TORRETA 



T. taxifolia survh'es the winters in very sheltered posi- 

 tions in the vicinity of Boston, but T. CaUfornica is 

 not hardy north. The Japanese T. nucifera is probably 

 the hardiest and most desirable species, but seems not 

 yet to have been tested north. Torreyas will probably 

 grow best in shaded and sheltered positions and in a 

 somewhat moist loamy soil. Prop, by seeds; also by 

 cuttings and by grafting on Cephalotaxus. Pla^^ts 

 raised from cuttings grow very slowly and usually re- 

 main bushy. For cions, terminal shoots should be 

 selected. 



There are 4 species in N America and E Asia. Trees,

 is much valued in Jipin for cal net making 

 and building. It is very durable in soil. In 

 this country it has been used for fence posts. 

 Raflnesque's Tumion has recently been taken 

 up as the proper name for this genus, since 

 the name Torreya was used for other genera 

 before being applied to this; but there are 

 good reasons why none of these older Tor- 

 reyas can stand, and no useful purpose can be served 

 by replacing the present name.

all of which are natives of the Rocky Mts., with linear 

 or spatulate, entire lvs. and rather large heads resem- 

 bling those of Aster; the numerous rays from violet to 

 rose -purple or white; flowering from early spring to 

 summer. The annual or biennial species have larger 

 heads than most of the perennials. Judging from the 

 literature, the largest fld. of the perennials are T. con- 

 densata, ]Vilcoxiana and Eothrockii, three species 

 which seem not to be in cultivation as yet. The species 

 mentioned below are presumably among the most de- 

 sirable of the genus. They are offered by collectors of 

 Colorado wild flowers. 



As a genus Townsendia is distinguished mainly by its 

 akene, which is commonly beset with bristly duplex 

 hairs, having a forked or glochidiate-capitellate apex. 

 Townsendiais practically unknown to floriculture. For 

 fuller account see Gray's Synoptical Flora of North 

 America.
