MALVACEAE. (MALLOW FAMILY.) 90 



else as in Sida, but the solitary kiduey-shaped seed ascending and the radicle 

 pointing downward, as in the former. (Name altered from Malva.) 

 . 1. M. anglistum, Gray. Annual, slightly hairy, erect (6'-l high): 

 leaves lance-oblong or linear, with scattered fine callous teeth ; flowers in the 

 upper axils, on peduncles shorter than the broadly ovate-triangular sepals ; 

 bractlets and stipules setaceous ; petals yellow, scarcely exceeding the calyx ; 

 carpels 5, kidney -shaped, smooth, at length 2-valved. W. Tenn. to Iowa 

 and Kan Aug. 



2 M. COCCineum, Gray. Perennial, low and hoary , leaves 5-parted or 

 pcdate , flowers in short spikes or racemes, the pink-red petals very much 

 longer than the calyx; carpels 10 or more, reticulated on the sides and inde- 

 luscent. Minn to W. Tex., and westward. 



6. SIDA, L. 



Calyx naked at the base, 5-cleft. Petals entire, usually oblique. Styles 5 

 or more, tipped with capitate stigmas ; the ripe fruit separating into as many 

 1 -seeded carpels, which are closed, or commonly 2-valved at the top, and 

 tardily separate from the axis. Seed pendulous. Embryo abruptly bent; 

 the radicle pointing upward. (A name used by Theophrastus.) 



1. S. Napaea, Cav. A smooth, tall (4-10 high) perennial; leaves 3-7- 

 cleft, the lobes oblong and pointed, toothed ; flowers (white) umbellate-corymbed, 

 1 ' wide ; carpels 10, pointed. Rocky river-banks, along the Alleghanies, Penn. 

 to Va. ; rare. (Cultivated in old gardens.) 



2. S. Elli6ttii, Torr. & Gray. A smooth, erect perennial (1 - 4 high) ; 

 leaves linear, serrate, short-petioled ; peduncles axillary, 1-flowered, short; 

 flowers (yellow) rather large; carpels 9-10, slightly and abruptly pointed, 

 forming a depressed fruit. Sandy soil, S. Va. and southward. May -Aug. 



S. SPixdsA, L. Annual weed, minutely and softly pubescent, low (10-20' 

 high), much branched; leaves ovate-lanceolate or oblong, serrate, rather long- 

 petioled; peduncles axillary, 1-flowered, shorter than the petiole; flowers 

 (yellow) small ; carpels 5, combined into an ovate fruit, each splitting at the 

 top into 2 beaks. A little tubercle at the base of the leaves on the stronger 

 plants gives the specific name, but it cannot be called a spine. Waste places, 

 S. New York to Iowa, and common southward. (Nat. from the tropics.) 



7. SPHJERALCEA, St. Hil. 



Ovules and seeds usually 2 or 3 in each cell. Characters otherwise as in 

 Malvastrum. (Name from a-Qcupa, a sphere, and dA/cca, a mallow from the 

 commonly spherical fruit.) 



1. S. acerifolia, Nutt. Perennial, erect, 2-6 high, stellately pubescent 

 or glabrate ; leaves maple-shaped, 3 - 7-cleft ; flowers clustered in the upper
