102 MALVACE^, 



base, rose-red with crimson veins : stamineal colurrm glabrotrs r styles 

 exserted : fr. ig ^- broad ; carpels not beaked, equalling the summit of 

 the axis. — Native of the islands off Santa Barbara and Sau Pedro ; long' 

 cultivated about San Francisco, where it is become spontaneous both in 

 the sand-dujies and along the seashore. Jan. — May. 



2. MALTA, Pliny (Mallow). Herbs with broad angular or rounded 

 leaves, and axillary solitary or glomerate flowers. Involucel 3-leaved. 

 Stamens and pistils as in Lavalera. Column of receptacle short, seeming 

 depressed below the whorl of achenes. 



1. M. PABvrPLOEA, Linn. Amoen. Acad. iii. 416 (1756) ; Greene, in W. 

 Am. Scientist, 155 ; Baker, Joum. Bot. xxviii. 341 ; M- obiusa, T. & G. 

 Fl. i. 225 (1838). Simple or branching, the branches depressed and only 

 a few inches long, or the main^ stem erect and 2 — 6 ft. high : herbage 

 more or less pilose-hairy : leaves long-petioled, obsoletely 5 — 7-lobed, 

 round-cordate, crenate, 1 — 3 in. broad : fl. glomei-ate, small, the pale blue 

 corolla little exceeding the calyx : bractlets linear : calyx accrescent, the 

 broad-lobed limb rotately spreading away from the mature fruit : achenes 

 glabrous or pubescent, transversely and sharply rugose on the back, 

 the acutely winged margins distinctly toothed. — A homely weed, 

 extremely common, often small and depressed when growing in the 

 streets or along country waysides, but in good soil erect with ascending 

 branches and sometimes (in southern parts of the State) ten feet high. 



2. M. BOKEALis, Wallm. in Liljebl. Sv. Fl. 2d ed. 218 (1798). Habit, 

 aspect and foliage of the last, but herbage more conspicuously pilose and 

 often a little stellate-hairy : bractlets lanceolate : calyx-lobes deep,, 

 closed over the mature fruit : corolla pale blue, }^ in. long, surpassing 

 the calyx : achenes reticulate-rugose, the acute margins entire. — Rather 

 common about Berkeley ; easily distinguished from the foregoing by the 

 larger flowers, connivent calyx-lobes, entire-margined and irregularly 

 rugose achenes, etc. The M. borealis of the " Botany of California " is 

 the preceding. I formerly took the present plant for M. Niarensis, All., 

 and specimens from middle Europe so named, but not authenticated, 

 misled me. Both our species of this genus are naturalized from Europe. 

 M. rolundifolia, so common on the Atlantic slope, has not appeared in 

 California. 



3. SIDALCEA, A. Gray. Herbs with rounded and commonly lobed 

 or parted leaves ; occasionally dioecious. Flowers in terminal racemes 

 or spikes, rose-purple or white. Involucel 0. Stamineal column double; 

 filaments of the outer series united into about 5 sets ; of the inner 

 distinct. Style-branches stigmatic lengthwise, as in Malca ; fruit the 

 same, except that the achene is sometimes beaked. 



* Annuals.
