 entire or 2-cleft ; flowers 5" long, narrow, not inflated, not recurvj^d, 

 very shortly pediceled ; calyx sparsely hairy, 10-nerved, teeth subu-

 corolla yellowish-white with a purple keel ; pod 2-seeded ; lower 

 petioles short ; pubescence villous, spreading.

escent form. It is, however, a mistake I think, to refer a_ thick- 

 rooted perennial to a slender annual. It is "undoubtedly distinct, 

 even if T. 7nonanthwn is a perennial (contrary to all our previous 

 knowledge of it) for the true T. monanihum, if other specimens so 

 referred by Mr. Watson are correct (and there is no doubt of his ac- 

 curacy in the matter) is a very delicate, prostrate, glabrous plant, 

 with slender, creeping, perennial rootstocks, while T. multicaule has 

 a thick, vertical root, which produces many ascending stems _; the 

 plant is softly hairy, and the flowers have a more conspicuous invo- 

 lucre and are more numerous. 



/Grindelia Pacific a.— Stems clustered, 6' high, erect or ascend- 

 ing, branching toward the top ; root-leaves filiform, 2-4 long, vary- 

 ing to very narrowly oblanceolate with a long filiform petiole, entire 

 or with a tooth or two at the summit ; upper stem-leaves oblong- 

 lanceolate ; short, sessile, with a broad, cordate, clasping base, entire 

 or sparsely toothed ; uppermost leaves passing into the mvolucral 

 scales, which are lax' and with filiform herbaceous tips 3"-i2 long; 

 involucre not over 6" broad ; rays yellowy 3" long ; heads terminal. 



On the hills at Santa Cruz, Cal. 



Very peculiar in the filiform root-leaves. 

 ■^ Spraguea umbellata, Torr., var. Montana.— Petals white, stamens 

 yellow ; scarious bracts 2"-^' long, very broad, equalling the sepals 

 and very conspicuous. 



Soda Springs, near Summit, Cal., July, 1882. 



This plant appears to be very distinct, but, after a careful com- 

 parison of several hundred specimens in various stages of develop- 

 ment, I find it shows a transition orsimiliarity in other respects, though
