 0. & y. Southern States to Texas ! June-Sept.— Stem 6-18 inches high, 

 often decumbent at the base. FloAvers and capsules larger than in L. major.

§ 2. Placenta firm and crustaceoiis, the margins not revolute : dissepi- 

 ments persistent, separating from the valves but cohering icilh the pla- 

 centce. — LEcnmiuM, Spach. 



4. L. Drummondii : decumbent and much branched at the base, shghtly 

 pubescent; leaves linear-subulate, scattered; racemes filiform, temninating 

 the numerous branches, loosely flowered; flowers unilateral, on capillary 

 spreading and at length reflexed pedicels; capsule globose-3-sided. — Lechi-

Dry places in small prairies, Texas, Druramond ! Dr. Leavenworth! 

 June-July.— The decumbent base of the stem slightly Hgneous ; the slen- 

 der branches 6-8 inches high. Pedicels twice the length of the flowers, 

 often supra-axillary, much longer than the setaceous bracts. Petals purple. 

 Stamens 3-4, Spach, "more than 10," Leavenworth, in lift. Seeds ovate. 



Lechea juncifolia, " foliis radlcalibus teretibus, calyce nullo," Walt. Car. f. 83. is 

 wholly unknown ; Wt doubtless belongs to some other order.

Sepals united at the base; the two outer ones subulate and often minute ; 

 the 3 inner oblong or oval, colored within, spreading in flower, connivent into 

 a tube in fruit. Petals 5, oblong-obovate, somewhat fugitive. Stamens 9-30, 

 Style filiform, straight: stigma minute. Capsule oblong-obovate, slightly 

 3-sided, 1-celled, 3-valved : placentfE parietal, nerviform, in the axis of the 

 valves. Seeds 1-2 (or by abortion fewer) from the base of each placenta, 

 on short filiform ascending funiculi, minutely granulated. Embryo (in H. 

 ericoides!) slender, spirally convolute in the midst of the thin albumen. — 

 Low difi'usely and excessively branched shrubby plants, each forming a 

 dense tuft. Leaves small, subulate or acerose, densely imbricated, exstipu- 

 late, tomentose, persistent. Flowers yellow, on slender peduncles or almost 

 sessile, terminating the short branches. 



1. H. ericoides (Linn.) : canescently pubescent, erect with the branches 

 decumbent; leaves subulate, slightly spreading; peduncles exserted, longer 

 than the flowers ; sepals acutish ; capsules oblong, slightly pubescent, about 

 3-&eedied.—Lin77. mant. p. 74 ; Willd. hort. Bcrol.t. 15; Pursh ! fi.2. p.
