ianus as Gray has latterly considered it. but it is a good variety 

 characterized by the flat, broad, short, closely appressed hairs 

 fixed almost by the base, and with the pod of A. Shortianus; 

 while the true A. Shortianus has the round, long and slender 

 hairs fixed by the base. The variety is ashy while the species 

 is silvery-villous with appressed hairs. 



Astragalus Shortianus Gray. var. minor Gray Proc. Am- 

 Acad vi 211 is true A. cyaneus and not a form of A. amphioxys 

 as Gray thought. 



Astragalus Douglasii (T & G) Gray var. Parishii (Gray) 

 (A Parishii Gray. Proc. Am. Acad, xix 75.) To this also belongs 

 A. l^cjoiiaisis Jones Cont. vii 644. The distinctions relied upon 

 by Gray do not hold out. There is but one very poor specimen 

 of A. Douglasii in the Gray Herbarium, all the other specimens 

 being referred to A. Parishii. 



Astragalus macrodon (H.& A. Bot. Beechey 333) Gray Proc. 

 Am. Acad, vi 216 about which there seems to have been much 

 doubt is, the writer believes, the same as A. holoscriccus Jones 

 Cont. vii. 638. 



Astragalus triflorus (DC. Ast. 62 t. I.) Gray PI. Wright 

 ii 45 is Candollcanus (HBK vi 495) Sheldon Minn. Bot. Stud. 

 Bull, ix 140. From a specimen in the Gray Herbarium, from the 

 writer's Mexican material and from the original figure it would 

 now appear that this is not distinct from .4. cerussatus Sheldon. 

 This will leave A. insularis Kell. to represent the Pacific Coast 

 plants with A. Pondii Greene as a possible variety of it. The 

 Pacific Coast species from lower Cal. has heretofore been re- 

 garded as the type of triflorus but it is a mistake, as is also the 

 statement that the type is from Peru. 



Astragalus insularis Kell. var. Quentinus. This includes 

 the slender forms with many leaflets, oblique pods nearly an 

 inch long, and plants nearly glabrous. The type specimens are 

 from San Quentin, Lower California, collected by Orcutt. This 

 has been called A. triflorus. 



AstkagalUs playanus. Annual, either glabrous or ashy on 

 the younger parts with closely appressed white hairs attached by 

 the base; stems ascending, rather robust to weak, a foot long,
