2. ANDROSACE L, Sp. Pl. 141.1753. 
Low annual or perennial herbs, our species scapose, with tufted small basal leaves, and 
terminal umbellate involucrate small white or pink flowers. Calyx persistent, 5-lobed, -cleft 
or -parted, the lobes erect in flower, sometimes spreading in fruit. Corolla salverform or 
funnelform, the tube short, not longer than the calyx, the limb 5-lobed, the lobes imbricated. 
Stamens 5, included, inserted on the tube of the corolla; filaments very short; anthers short, 
oblong, obtuse. Ovary superior, turbinate or globose; ovules few, or numerous, amphitrop- 
ous; style short; stigma capitellate. Capsule turbinate, ovoid or globose, 5-valved from the 
apex, few-many-seeded. [Greek, man’s shield, from the shape of the leaf in some species. ] 
About 50 species, natives of the northern hemisphere. Besides the following, 4 others occur 
in western and northwestern North America. 
1. Androsace occidentalis Pursh. 
Androsace. (Fig. 2808.) 
Androsace occidentalis Pursh, Fl. Am. Sept. 137. 1814. 
Annual, minutely pubescent, or glabrate; scapes 
filiform, solitary or numerous from fibrous roots, erect 
or ascending, or diffuse, 1/-3/ long. Leaves oblong or 
spatulate, obtuse, entire, sessile, 3/’-8’ long; bracts of 
the involucre similar to the leaves but much smaller, 
1//-3// long; pedicels several or numerous, filiform, 
2//-6/’ long in flower, often becoming 1’ long in fruit; 
calyx-tube obpyramidal in fruit, the lobes ovate or tri- 
angular-lanceolate, acute, as long as or longer than the 
tube, green, becoming foliaceous; corolla very small, 
white, shorter than the calyx; calyx longer than the 
several-seeded capsule. 
In dry soil, Minnesota and Illinois to Kansas and 
Arkansas, west to the Northwest Territory, Utah and New 
Mexico. April-June. 
3. HOTTONIA L. Sp. Pl. 145.1753. 
Aquatic glabrous herbs, rooting in the mud, or floating, with large pinnatifid submersed 
crowded leaves, and small white or purplish flowers, racemose-verticillate on bracted hollow 
erect emersed peduncles. Calyx deeply 5-parted, the lobes linear, imbricated, persistent. 
Corolla salver-form, the tube short, the limb 5-parted, the lobes spreading, imbricated at least 
in the bud. Stamens 5, included, inserted on the tube of the corolla; filaments short; 
anthers oblong. Ovary ovoid; style filiform; stigma minute, capitate; ovules numerous, 
anatropous. Capsule subglobose, 5-valved. Seeds ellipsoid, numerous. [Dedicated to 
Peter Hotton, 1648-1709, professor at Leyden. ] 
Two species, the following of eastern North America, the other of Europe and eastern Asia.

eine Featherfoil. (Fig. 2809.) 
Ge tte SN i\ , Hottonia inflata Ell. Bot. S. C. & Ga. 1: 231. 1817. 
Stem entirely submerged, spongy, densely 
leafy, branched, sometimes 2° long. Leaves 
sessile, or nearly so, ovate or oblong in out- 
line, divided very nearly to the rachis into 
narrowly linear entire segments 14/—2’ long, 
\//-1/’ wide; peduncles several in a cluster 
at the ends of the stem and branches, partly 
emersed, hollow, jointed, constricted at the 
joints, 3’-S’ high, the lower joint 2/-4’ long, 
sometimes 1’ thick, the others successively 
smaller; pedicels 2’’-12’’ long; flowers 2’/-3/’ 
long in verticils of 2-10 at the joints, sub- 
tended by linear bracts; corolla white, shorter 
than the calyx; capsule globose, about 114’ 
in diameter.
