24 LEGUMINOS^. 



or less pilose-villous : stipules ovate-lanceolate, entire, setaceously acumi- 

 nate : leaflets linear-cuneate, the sides remotely toothed, apex bifid and 

 mucronulate : pedimcles slender, exceeding the leaves : heads 6—15- 

 flowered : calyx deeply 5-parted, the teeth subulate-setaceous, about 

 eqiialling the minute pale rose-colored corolla : pod included, 1-seeded : 

 seed rather narrowly obovate-oblong. Var. decipieiis. Taller and 

 stouter, the leaflets cuneate-oblong with closely serrulate margins and 

 only a shallow notch at apex ; heads 15 30-flowered. — The type is 

 common from Santa Clara Co., Torrey, Lemmon, to Solano, Jepson, and 

 Mendocino, Bolander, but chiefly to the east of the Coast Range. In the 

 Bay district the variety alone is found ; and this has hitherto been con- 

 fused with T. gracilenlum, from which its pallid hue, hairy stalklets 

 and calyces, as well as its flowers and fruits make it easily distinguishable. 



4. T. ciliolatum, Benth. PI. Hartw. 304 (1S49) ; T. ciliatum, Nutt. PI. 

 Gamb. 152 (1848), not of Clark. Erect, 1—2 ft. high, glabrous : stipules 

 narrow, acuminate ; leaflets cuneate-oblong or obovate, ^j 1 in. long, 

 obtuse or retuse, serrulate : fl. purple, 3 lines long ; calyx-teeth lance- 

 olate, very acute, rigidly ciliolate. — Throughout the western part of the 

 State, both seaward and in the interior. Apr. — June. 



5. T. PROCUMBENS, Linn. Sp. PI. 772 (1753). Ascending or suberect, 

 slender, pubescent : leaflets cuneate-oblong, emargiuate, denticulate, the 

 terminal one on a longer stalklet : heads ovate or oblong, very dense ; 

 fl. yellow : upper calyx very short ; banner deflexed over the other 

 petals in age.- -A small and delicate Old World clover with pinnately 

 8-foliolate leaves, small yeUow flowers ; beginning to appear spontane- 

 ously ; frequent in lawns, having been introduced with lawn-grass seeds. 



6. T. REPENS, Rivinus, Tetrap. 17 (1690), Perennial, diffuse, creeping, 

 sending up erect long-stalked glabrous leaves and heads : leaflets ob- 

 cordate, denticulate : heads depressed-globose, at length umbellate : fl. 

 white ; calyx-teeth unequal, lanceolate-subulate, shorter than the tube : 

 pod about 4-seeded. — The common White Clover of eastern and European 

 meadows and pastures ; a troublesome plant in lawns with us ; sparingly 

 naturalizad in our district, yet common in the wild state in Oregon, etc. 



7. T. Bolanderi, Gray, Proc. Am. Acad. vii. 335 (1868). Perennial, 

 cespitose, glabrous : leaflets obovate-oblong, }4 in. long, reticulate, serru- 

 late : peduncles few, elongated, exceeding the leaves : fl. few, 3—4 lines 

 long, purplish : calyx-teeth lanceolate, not longer than the tube : pod 

 2-seeded. — Moist ground in the neighborhood of the Yosemite, above the 

 valley. 



8. T. Kiii^i, Wats. Bot. King Exp. 59 (1871). Perennial, erect, 6 10 

 in. high, glaljrous : stipules lanceolate, aciiminate, entire : leaves long-
