GERANIACE^. 99 



purple or lilac petals longer : beak of carpels 2 — 3 in. long. — Common 

 toward the foot-hills skirting the eastern borders of the interior plains, 

 near Sacramento, lone etc. ; also in Marin Co. in many places. 



* * Native species ; leaves simple^, rounded. 



4 E. macrophyllnm, H. & A. Bot. Beech. 327 (1840). Subacaulescent, 

 4—10 in. high, soft-pubescent and with some gland- tipped pilose hairs , 

 leaves 1 — 3 in. broad, reniform-cordate with a broad open sinus, crenate- 

 serrate : peduncles exceeding the leaves : sepals oblong, accrescent, at 

 length }-2 in. long ; petals equalling them, pure white : carpel clavate, 

 ig in. long (excluding the 1 in. beak), densely velvety-pubescent : seed 

 ■oblong linear, }^ in. long, dull, smooth. — Plains of the interior ; also 

 toward the seaboard in Marin Co., northward to Oregon. Mar. Apr. 



5. E. Califoriiicuiii. Caulescent, the stem exceeding the rather few 

 radical leaves, 6 — 12 in. high ; herbage without soft pubescence, but 

 upper part of stem and growing parts with abundant spreading hairs 

 tipped with pivple glands : leaves broadly cordate-ovate with closed 

 sinus, slightly 5-lobed, rather coarsely crenate, the teeth obtuse, mucronu- 

 late : 11. much as in the preceding but petals deep rose-red : fruit 

 unknown. — Berkeley Hills and eastward in the Mt. Diablo Range. 

 Sufficiently unlike the preceding, though little known and seeming rare. 

 The herbage has a redtlish tinge, and the leaf bears a deep red-purple 

 spot or zone near the base. The stem-leaves are more deeply and sharply 

 lobed than the radical, and the species is in some points more like 

 E. Te.raauin^ yet very distinct from that also. Apr. 



3. TR0PJ:0LUM, Uanieus (Nasturtium). Tall leafy climbing 

 plants, the succulent herbage with a pungent juice. Leaves alternate, 

 simple, exstipulate. Flowers large, axillary, solitary, irregular. Sepals 

 not quite distinct ; the 3 upper somewhat conjointly produced at base 

 into a long spur. Petals 5, unequal ; the 3 lower often shorter. Stamens 8, 

 distinct from the very base. Carpels 3, becoming large corky sulcate 

 achenes. 



1. T. MAJus, Linn. Sp. PI. i. 345 (1753) ; Curt. Bot. Mag. t. 23. Leaves 

 orbicular, peltate, repandly lobed : petals usually orange-red, 1 — 2 in. 

 long, broad and obtuse, unguiculate, the 3 lower fimbriate lacerate at the 

 base of the blade : achenes }-^ — % in. in diameter. — Native of Peru ; 

 escaped from cultivation in many places in California, especially south- 

 ward, at Santa Barbara, etc.; also near Belmont, San Mateo Co. 



4. FLOERKEA, Willdenow. Low annuals, slightly succulent, the 

 juice pungent. Leaves alternate, pinnately cleft, exstipulate. Flowers 

 axillary, solitary, regular, 3 — 5-merous (all ours 5-merous, or by exception 

 4-merous). Sepals valvate in bud. Petals convolute, as many hypogynous
