tion for the variety caudata was not near Santa Fe, New 

 Mexico, but ** by streams in the valleys of the Rocky Moun- 

 tains, toward their western slope, in Oregon, and also the 

 Blue Mountains" (Nuttall, I. c). However, the Santa Fe 

 specimen was var. caudata^ a staminate one with thick, short- 

 peduncled aments and young leaves about 2 inches long. The 

 S. lasiandra from near Lewiston, Idaho, was also staminate, 

 with similar leaves and more slender aments on longer pe- 

 duncles. So when he collected in Chehallis Co., Wash., his 

 Lyallii tj^pe, a pistillate specimen with maturing aments 3 in. 

 long, and the leaves so well developed that they are 2-4^ in. long 

 and larger, becoming glaucous, it naturally looked ** very dif- 

 ferent " to him. As for the characters quoted from the Silva, 

 they are by no means constant. A critical study of 33 sepa- 

 rate collections, comprising 40 sheets, fails to discover that 

 the large leaved form is more frequently accompanied by a 

 linear, glabrate scale than by a lanceolate, oblong, or oblan- 

 ceolate hairy one. Most young leaves and many mature ones 

 are narrowed at the base and are frequently narrowly oblong- 

 acuminate rather than tapering regularly from near the base. 

 In Heller's type they are still distinctly oblanceolate^ acumi- 

 nate, with no more petiolar glands than usual. These glands, 

 and also the stipules, are generally proportional to the size, 

 of the leaf. Nuttall's figure shows no glands at all.
