25. R. lobbii Gray. Lobb's Buttercup. Annual; submersed leaves none, 

 or when present, few and as in R. aquatilis; floating leaves 6 to 9 lines broad, 

 divergently 3-parted into oblong or ovate lobes, the lateral lobes notched and 

 the middle one connnonly entii'e, or, rarely, all notched; stamens 5 to 10; petals 

 withering i)ersistent ; style filiform, aljont 3 times the lengtli of the ovary ; achenes 

 few (4 to 6), rugose, the mature ones commonly witli minute black dots. 



Whitening the surface of shallow vernal pools: Alameda and Marin cos. to 

 Napa Valley and northern Sonoma. North to British Columbia.

14. KUMLIENIA Greene. 

 Glabrous perennial with the leaves and 1-flowered scapes from a fascicle of 

 thickened or fleshy-fibrous roots. Leaves all basal, roundish, sballowly 3-lobed 

 and sparingly toothed, cordate or truncate at ba.se. Sepals 5 or 6, white. Petals 

 5 or 6, minute, reduced to small yellow stiped nectaries. Achenes sub-follicular, 

 capitate, mendjranous, lanceolate, attenuate upward into a broadly subulate beak 

 hooked or coiled at the tip, 2 (or 3) -nerved on the sides, at least when dead 

 ripe. Seed fusiform, longitudinally multi-striate. — Species 2, North America.

1. K. hystricula Greene. Scapes 2 to 9 inches high ; leaves roundish in out- 

 line but broader than long, lo to 2i'2 inches broad, on i)etioles % to 2 inches 

 loiig; flowers 5 to 7 (or 12) lines broad; sepals oval; nectaries spoon-.shaped, 

 one line long; achenes weakly pubescent, 2 to 21/; lines long; seed % line long. 

 Clefts of rocks on moist caiion sides, often within reach of flying spray : 

 Sierra Nevada at middle altitudes (1500 to 5000 feet). North to Oregon. Mar.- 

 June. 



Tax. Note. — The flowers as seen in tlieir native habitat are delicately engaging and some- 

 what suggestive of those of Anemone quinquefolia. While individuals are not uncommon in 

 favored spots, specimens are rare in herbaria. Quite dead ripe fruit is seldom collected. 

 Some very mature material from El Dorado Co. is available to us and on examining it we 

 find that the cai-jjels in extreme age split roughly but spontaneously from the base upward 

 along the ventral and dorsal lines into two equal valves, thus releasing the single seed. Were 

 these carpels not capitate, they would, it seems certain, be termed follicles. Our species may 

 belong to the genus Oxygi-aphis Bunge, but the type of that genus is known to us only from 

 somewhat insufficient descriptions.

15. CLEMATIS L. Virgin's Bower. 

 Stems woody below, climbing by aid of the petioles of the opposite compound 

 leaves. Peduncles axillary, bearing 1 to numerous flowers. Flowers (in ours) 

 polygamous. Sepals 4, valvate in the bud, white and petal-like. Petals none 

 (in ours). Stamens numerous. Achenes numerous in a head-like cluster, the 

 styles persistent as hairy or plumose tails, very conspicuous in fruit. — Species 

 about 170, all continents. (Ancient name, from Greek klema, a twig.)
