Calandrinia Howellii. Closely resembling C. Cotyledon: leaves 

 more narrowly spatulate, 3 inches long or less, entire at the summit, 

 the narrowly scarious margin crisped-undulate : scapes and inflores- 

 cence as in C. Cotyledon, but the flowers sessile or nearly so ; petals 

 6 to 8 ; stamens 5 to 7, the narrow filaments slightly coherent below : 

 ovary 2-4-valved ; seeds 4 to 10. — On the Deer Creek Mountains 

 in Josephine County, Oregon (Thomas Howell, July, 1887); also in 

 cultivation at Cambridge. The leaves of C. Cotyledon are not at all 

 crisped upon the margin, and have usually a few small teeth at the 

 summit. The seeds of both species are ecarunculate, black and 

 shiniug. 



Sidalcea Hendersoni. Tall and apparently perennial (3 or 4 

 feet high), glabrous throughout, the stem simple or nearly so : leaves 

 palmately 7-cleft to below the middle, the mostly broad segments 

 coarsely lobed and toothed, the upper leaves 3-5-parted and the seg- 

 ments narrower : flowers large (9 to 12 lines long), in a loose raceme, 

 the pedicels (1 to 3 lines long), shorter than the linear bracts: calyx 

 large Q inch long in fruit), the lobes ovate-lanceolate, shortly acumi- 

 nate : carpels few (8), smooth and glabrous, 2 lines long including 

 the conspicuous linear beak. — Near the shore of Clatsop Bay, Oregon 

 (L. F. Henderson, July, 1887). 



Trifolium Howellii. Perennial (?), glabrous throughout, the 

 stout stems 2 feet long : stipules large, lanceolate to ovate ; petioles 

 short ; leaflets mostly cuneate-oblanceolate, 1 i- to 3 lines long, irregularly 

 toothed : peduncles axillary, exceeding the leaves : heads naked, ovate 

 or oblong, the short-pedicellate flowers soon reflexed: calyx-teeth nar- 

 row, about equalling the tube ; corolla 4 or 5 lines long : pod 2-ovuled, 

 1-seeded, a little exceeding the calyx. — Of the T. ciliatum group. In 

 the Siskiyou Mountains, southern Oregon (Thomas Howell, July, 

 1887). 



Astragalus sylvaticus. Near A. tricarinatus and A. albens : 

 glabrous, the decumbent or ascending stems a foot long or more : leaf- 

 lets 8 to 10 pairs, oblong, retuse, 4 to 9 lines long: peduncles equal- 

 ling or exceeding the leaves ; racemes small, close (about an inch 

 long) : calyx very slightly pubescent, the acuminate teeth about equal- 

 ling the campanulate tube ; petals ochroleucous, 3 or 4 lines long : pod 

 chartaceous, sessile, linear and more or less curved, compressed, 2-celled 

 by the intrusion of the dorsal suture, the ventral acute, 6 to 8 lines 

 long by 1^ broad. — Near Glendale in southern Oregon, "in open 

 gravelly ground" (L. F. Henderson) or "in dense forests" (Tlwmas 

 Howell, June, 1887, — who suggests the name).
