Rowlee : North American Willows 249 



i. Salix microphylla Cham, and Schlecht. Linnaea, 6: 354. 



1831 



Heretofore this species has been considered identical with .S. 

 taxifolia H.B.K. A comparison of the original descriptions, both 

 of which were very carefully drawn, indicates that the two are dis- 

 tinct. The plate and description by Hooker and Arnott in Bot. 

 of Beechy, Voy. 31. //. 70, confirms the conclusion that this spe- 

 cies is distinct. I have seen but one specimen : Palmer's no. 1 193, 

 11 a shrub 4 ft. high growing on the bank of a river " at Colima, Mex- 

 ico. It is well said in Hooker and Arnott' s description that this is 

 " a very remarkable species of Salix with leaves like those of some 

 small Ly thrum" So far the pistillate plant has not been seen. 



2. Salix taxifolia H.B.K. Nov. Gen. et Sp. 2:22 



This species is well described and illustrated in Sargent's 

 North American Sylva. It has been collected by Pringle and 

 Tuomey in Arizona, also by Pringle in Chihuahua, Mexico. It is 

 a large shrub or small tree. 



J 3. Salix Parishiana sp. no v. 



A slender shrub, one to three meters high, bark grayish or 

 brown, young twigs cinereous strigose : leaves linear-lanceolate, 

 minutely and remotely denticulate, 5-7 cm. long by 3 mm. wide, 

 silky canescent when young, glabrous and somewhat coriaceous 

 when mature, veins few but very prominent : stipules none : 

 aments on long leafy peduncles, appearing about April I, 2-3 

 cm. long by 1—2 cm. peduncles often 10 cm. long, the upper 

 leaves of the branch much surpassing the ament : ament densely 

 flowered, scales white densely villous all over, oblong, acute : fila- 

 ments scantly hairy at the base : capsules densely villous, oblong, 

 closely sessile : style distinct : stigmas linear, three times as long as 

 thick. 



A very peculiar form, differing from 5. taxifolia by its larger 

 leaves and cylindrical aments and quite distinct from other species 

 with linear stigmas.

 Hobby, nos. 54, 55), Springs Valley, Inyo Co. (F. V. Coville and 



F. Funston, no. 263). 



Mr. S. B. Parish writes "that it is not uncommon near San 



Bernardino."
