MALVACEAE. (MALLOW FAMILY.) 
five 2-beaked pods, opening between the beaks. — Waste places, from 
S. New York soutliwestward. — A homely weed, with small yellow 
flowers. A little tubercle at the base of the leaves on the stronger 
plants gives the specific name, but it cannot be called spiny. 
S. Nap&a, the Napaa Icevis , L., well known in gardens, which was 
first raised by Hermann at Leyden from seeds said to have come from 
Virginia, is not known to grow wild in the Northern States, and I 
doubt if it really belongs to this country at all. 
3. NAPiEA, Clayt. Glade Mallow. 
Calyx naked at the base, 5-toothed. Flowers dioecious; the 
staminate flowers entirely destitute of pistils; the fertile with a 
short column of filaments but no anthers. Styles mostly 8, dis¬ 
tinct almost to the base, stigmatic along the inside. Fruit depress¬ 
ed-globular, separating when ripe into as many 1-seeded pods as 
styles. Radicle pointing downwards. — A tall and roughish per¬ 
ennial herb, with very large 9 - 11-parted lower leaves, the point¬ 
ed lobes pinnatifid-cut and toothed, and small white flowers in 
panicled clustered corymbs. (Named by Clayton from vany, a 
wooded valley, or mountain glade, or, poetically, the nymph of 
the groves, alluding to the place where he discovered the plant.) 
1. IV# dioica, L. (Sida dioica, Cav.) — Limestone valleys, 
Penn., southward to Augusta Co., in the Valley of Virginia, where 
Clayton discovered it, west to Ohio and Illinois ; rare. July. — Root- 
leaves 1° - 2° broad. 
4. MiLTA, L. Mallow. 
Calyx with a 3-leaved involucel at the base, like an outer calyx. 
Styles numerous. Fruit depressed, separating at maturity into as 
many 1-seeded and usually indehiscent kidney-shaped little pods 
as there are styles. Radicle pointing downwards. — Flowers 
perfect. (An old Latin name, from MaXa^, alluding to the emol¬ 
lient leaves.) 
1. MI. rotlllldifolia, L. (Dwarf Mallow.) Stems pros¬ 
trate or spreading from a deep root; leaves rounded-heart-shaped, ob¬ 
tusely 5-lobed, crenate, long-petioled ; flowers solitary, axillary ; pet¬ 
als notched at the end, twice the length of the calyx. 1J. — Around 
dwellings everywhere, introduced, troublesome. — Corolla small, 
whitish, with purple veins. 
2. in. sylvestris, L. (High Mallow.) Stems erect; leaves 
rather sharply 5 - 7-lobed ; flowers axillary, 3-4 together ; petals in-
