Malvastrum. MALVACEAE. 5 



the slender petiole : raceme often dense : calyx-lobes acute or acuminate, 2 to 4 lines 

 long : petals scarlet, 6 to 9 lines long : carpels oblong, 2 lines long, rounded or 

 shortly beaked above, reticulated on the sides near the base, pubescent on the back. 

 PL Fendl. 21 ; Watson, Bot. King Exp. 47. Malva Munroana, Dougl.; Lindl. 

 Bot. Reg. xvi, t. 1306 ; Bot. Mag. t. 3537. 



From Washington Territory to Nevada and Utah ; found eastward of the Sierra Nevada. 



2. M. Thurberi, Gray. Shrubby at base, 3 to 5 feet high, with wand-like 

 branches, densely tomentose : leaves thick and subrugose, shortly petioled, the upper 

 nearly sessile, rounded, cordate or truncate at base, somewhat 3 - 5-lobed, crenate, 1 

 to 1^ inches long : flowers small, nearly sessile in an interrupted naked spike, or 

 the inflorescence more expanded and racemose : calyx-lobes short, acute : fruit 

 broadly obovate, the carpels 1^ lines long, rounded or subtruncate above, becoming 

 glabrous, not reticulated. PL Thurb. 307. Malva fasciculata, Xutt. 1. c. 225. 



In the Coast Ranges of Southern California ; at Pacheco's Pass (Bolander), Santa Barbara 

 (Xuttall), San Diego (Parry), and in Sonora (Thurber). No. 554 Brewer, from the Santa Lucia 

 Mountains above the Nacimiento, is probably the same, but with the flowers fewer and less 

 crowded, and the leaves rounded-rhoniboidal and veiy tomentose ; described as very fragrant. 



3. M. splendidum, Kellogg. A shrub 10 to 12 feet high or more, the branches 

 and leaves gray-to rnentose : leaves shortly petioled, cordate-ovate, 5-lobed, the lobes 

 acute and crenate : flowers nearly sessile in terminal branching panicled racemes, the 

 spreading peduncles 1 to 2 inches long : calyx-lobes short, acute : carpels oblong, 

 1 \ lines long, rounded at each end, with a short mucronate beak above, becoming 

 glabrous, reticulated on the sides below. Proc. Calif. Acad. i. 65. 



Imperfectly described by Dr. Kellogg from a small specimen collected in the neighborhood of 

 Los Angeles and said to have been taken from a tree 1 5 to 20 feet high and a foot in circumference. 

 The above description is based upon specimens found by Prof. Brewer in the Sierra Santa Monica, 

 which accord sufficiently well with the original account. Differing from the last mainly in the 

 form of the leaves and in the open inflorescence. 



4. M. marrubioides, Durand & Hilgard. Densely pubescent, two feet high : 

 leaves thick and shortly petioled, ovate, subcordate, obscurely 3-lobed, acutely ser- 

 rate : flowers nearly sessile, in paniculate clusters of 3 to 5 in a somewhat naked 

 raceme : calyx-lobes long-acuminate, little shorter than the rose-colored petals : carpels 

 rounded or oblong, glabrous, not reticulated. Pacif. E. Eep. v. 6, t. 2. 



Collected only near Millerton on the San Joaquin, Heermann. 



5. M. Coulteri, Watson. Branches slender, somewhat pubescent : leaves an 

 inch or less in length, ovate-subcordate, 3 - 5-lobed, acutely toothed, equalling or 

 exceeding the slender petioles : flowers small, in a rather loose raceme : calyx-lobes 

 acuminate : petals 4 or 5 lines long, rose-color : carpels rounded, less than a line in 

 diameter, with a thin horizontal oblong projection inward at base, very strongly 

 reticulated, pubescent on the under surface. Proc. Am. Acad. xi. 125. 



Collected by Coulter (n. 96) probably in Southeastern California, and by Schott in the Gila 

 bottom on the Mexican Boundary Survey. Well distinguished by its peculiar carpels. 



* * Annuals. 



6. M. rotundifolium, Gray. Eather stout and sparsely hispid with spreading 

 hairs, two feet high or less : leaves reniform, obscurely lobed, coarsely toothed, the 

 lower long-petioled : flowers loosely clustered, the lower pedicels elongated : calyx 

 4 or 5 lines long, with acuminate lobes enlarging in fruit : petals broad, \ inch long, 

 light purple with a red spot at base : carpels 40 or more, thin, circular, 1| lines 

 broad, glabrous, reticulated ; the axis dilated. Proc. Am. Acad. vii. 333. 



On sand-hills near Fort Mohave (Cooper), and eastward in Arizona. 



7. M. exile, Gray. Decumbent, the stems becoming a foot long or more, pubes- 

 cent : leaves 6 to 9 lines broad, broadly ovate, cordate or truncate at base, deeply 

 5-lobed, sparingly toothed, equalling the petioles : flowers mostly solitary and axillary,
