1. HOUSTNIA, L.

Calyx 4-lobed, persistent; the lobes in fruit distant. Corolla salver-form or funnel-form, usually much longer than the calyx-lobes, 4-lobed, the lobes valvate in the bud. Stamens 4; anthers linear or oblong. Style 1; stigmas 2. Ovary 2-celled. Pod top-shaped, globular, or didymous, thin, its summit or upper half free from and projecting beyond the tube of the calyx, loculicidal across the top. Seeds rather few (4--20 in each cell), peltate and saucer-shaped or globular-thimble-shaped, pitted.--Small herbs, with short entire stipules connecting the petioles or narrowed bases of the leaves, and cymose or solitary and peduncled flowers. These are dimorphous, in some individuals with exserted anthers and short included style; in others the anthers included and the style long, the stigmas therefore protruding. (Named for _Dr. Wm. Houston_, an English botanist who collected in Central America.)

[*] _Small and delicate, vernal-flowering; peduncles 1-flowered; corolla salver-form; upper half of the broad and somewhat 2-lobed pod free; seeds globular, with a very deep round cavity occupying the inner face._

3. H. patens, Ell. An inch to at length a span high, with ascending branches and erect peduncles; leaves spatulate to ovate; corolla much smaller than that of n. 1, violet-blue or purplish without yellowish eye, _the tube longer than its lobes, twice the length of the calyx-lobes_.--Dry or sandy soil, S. Va. to Tex. and Ill. (?)

Fruit dry and hard, small, inversely pyramidal, 2--4-celled, at length splitting from the base upward into 2--4 closed 1-seeded portions.--Shrubs, with the white flowers densely aggregated in spherical peduncled heads.

Flowers occasionally 3--6-merous, always dimorphous; all those of some individuals having exserted stamens and included stigmas; of others, included stamens and exserted style. (This very pretty plant commemorates _Dr. John Mitch.e.l.l_, an early correspondent of Linnaeus, and an excellent botanist, who resided in Virginia.)

1. M. repens, L.--Dry woods, creeping about the foot of trees, especially Coniferae, throughout our range and southward. June, July.--Leaves often variegated with whitish lines. Rarely the two flowers are completely confluent into one, with a 10-lobed corolla.

Fruit small and dry, 2-celled, 2-seeded, splitting when ripe into 2 carpels, one of them usually carrying with it the part.i.tion, and therefore closed, the other open on the inner face.--Small herbs, the bases of the leaves or petioles connected by a bristle-bearing stipular membrane. Flowers small, whitish, crowded into sessile axillary whorled cl.u.s.ters or heads. (Name compounded of sp??a, _seed_, and a????, _a point_, probably from the pointed calyx-teeth on the fruit.)
