brauchlets : calyx 3 lines long, subtended by 3 setaceous bractlets ; 

 segments ovate-lanceolate, acuminate : corolla i^ in. long or less : carpels, 

 snborbicular, i^ line long, wholly indehiscent, very conspicuously favose- 

 reticulate both dorsally and laterally : the minute reniform seed smooth, 

 glabrous.— Known only in a single fragmentary specimen, deposited in 

 the herbariiim of the University long ago, with a few other specimens, 

 all said to have been gathered near Monterey ; the collector's name not 

 known. There is a blunt incurved very short vacant apex to the achene, ' 

 suggesting that the shrub may perhaps as well be a Sphivralcea. 



9. M. Muiiroanuiii, Gray, PI. Fendl. 21 (1849) : Dougl. in Bot. Eeg. t. 

 1306 (1830), under Malva. Branching from a mere woody base, 1— 2^^ 

 ft. high, hoary with a scattered stellate-pubescence : leaves broadly 

 ovate, cordate, 3— 5-lobed and acutely or crenately toothed, 12 in. long, 

 exceeding the petiole : fl. in short and rather dense terminal and sub- 

 terminal racemes : calyx-lobes acute or acuminate, 2—4 lines long : 

 corolla scarlet, ^i—% in. long : carpels 2 lines long, oblong, rounded or 

 short-beaked above and pubescent, reticulate on the sides toward the 

 base.— A fine showy species of the Interior Basin, reaching our borders 

 along the eastern base of the Sierra. 



7. SPHJIRALCEA, A. Hi. Hilaire. In all respects like Malvastrum 

 except that the fruit is conical rather than depressed, the carpels being 

 longer and 2-ovuled ; the lower seed ascending, the upper pendulous 

 (when not wanting by abortion of the ovule). 



1. S. iucaua, Torr. in Gray, PI. Wright, i. 21 (1852), PI. Fendl. 23 

 (1849), name only : S. Emoryi, Torr. in Gray 11. cc. Rather slender, 

 1 2 ft. high, softly canescent with minute pubescence : leaves ovate- 

 cordate, slightly 3— 5-lobed, crenate : calyx and scarlet corolla as in 

 Malvastrum Munroanum, which the plant much resembles, differing 

 chiefly in the longer 2-seeded carpels forming a truncate-conical fruit.— 

 The publication of this dates from the Plant:© Wrightianse, only the 

 names having been given in the Plantse Fendlerianse. In both places 

 the name iucaua precedes Emofi/i. The plant comes barely within our 

 limits along the eastern base of the Sierra, but is common in Arizona, 

 New Mexico, etc. 



8. ABUTILON, Camerarius. Herbs or shrubs, usually soft-tomentose, 

 with axillary solitary mostly yellow flowers. Involucel 0. Stamineal 

 tube simple, autheriferous at summit. Styles 5 or more, with capitate 

 stigmas. Fruit truncate-globose or -conical ; carpels dehiscent, several - 

 seeded. 



1. A. AvicENN^, Gsertn. Fr. et Sem. ii. 251 (1802). Sida Abutilon, 

 Linn. Sp. PI. ii. 685 (1753). A stout erect branching annual, 2—6 ft. 

 high, the herbage green but velvety-pubescent and almost oily to the
