Ps asia 
LOMATIUM MACROCARPUM semivittatum var. nov. 
Ultimate leaf segments very narrowly linear or filiform: fruit 
narrowly winged, the dorsal ridges low ; no oil-tubes on the dorsal 
side, 2-6 on the commissural side. 
Orecon: Hood River, May 24, 1886 and Aug. 6, 1883, 
Henderson, 397 (type); Hood River, Mrs. Barrett, 71. 
WASHINGTON: West Klickitat County, Suksdorf, 279. 
This form differs from ZL. macrocarpum essentially as above. 
It may be a distinct species as all of the specimens of the typical 
form or of the preceding variety that we have examined have dor- 
sal oil tubes. The Henderson specimens were referred by Coulter 
and Rose to P. bicolor Wats. in the Revision of the North 
American Umbelliferae. It resembles that species only in foliage. 
- Astragalus Whitedii sp. nov. 
Hoary pubescent throughout, the erect or ascending stems 40- 
50 cm. high, simple or sparingly branched : leaflets 5-7 pairs, ob- 
long or obovate, truncate or emarginate at apex, acute at the 
nearly sessile base, 5-10 mm. long, the pubescence similar on 
both faces ; stipules small : peduncles mostly exceeding the leaves: 
racemes short, few (5—7)-flowered: calyx cylindric campanulate, 
the pubescence blackish, the short teeth one fourth as long as the 
tube: corolla yellowish-white, twice as long as the calyx: pods 
linear, cartilaginous, 1-celled without sutural intrusions, 2.5—3 ¢™: 
long, acute, rather turgid, sparsely pubescent, curved into a semi- 
circle, the stipe-like base as long as the calyx.
