4. L. STRIATUM, Walt. Fl. Carolin. 117. L. Virgintaniim, Reich. L. 

 Virginianum, var. ofpositifoltu^n, Engelm. L. rigidum. Torr. «& Gr., in 

 part. L. Virgitiiatium, var. } diffustim and L. difusuin. Wood. — A foot 

 or two high; stems simple or subcespitose, ascending, striate and some- 

 what wing-angled even below ; leaves opposite below the first branch, 

 elliptical-oblong, acute, i-nerved ; flowering branches mostly short and 

 spreading, at length racemose along the stem; capsule subglobose; oth- 

 erwise like the last. — Bogs and wet places, Canada to the Gulf, and west 

 to Arkansas. 



The leaves are of a yellower green than in the last, and, as indicated 

 by Austin, the plant is slightly viscid, so as to adhere a little to the paper 

 when in press. Specimens that clearly belong here were collected in dry 

 soil in Canada by Macoun, but the species is usually found in wet places. 



5. L. Neo-Mexicanum, Greene, Bot. Gazette, vi. 1S3. — Annual or 

 biennial, glabrous, a foot or two high; stems considerably branched 

 below, strict, striate and angled above; leaves alternate except the lower- 

 most, oblong, the lower mostly obtuse and the upper acute, i-nerved 

 (2X8-15 mm.), without stipular glands; flowers often on rather long 

 erect pedicels (at length 5-10 mm.) forming long virgate racemes; sepals 

 lanceolate, obtuse, acute or abruptly taper-pointed, keeled, the inner with 

 minutely glandular margins; petals oblong-spatulate, about 5 mm. long, 

 one-half exceedmg the calyx; stamens and pistil equal to the petals; 

 styles distinct; capsule ovoid- acute, somewhat constricted below the 

 top, 3-4 mm. long, a little longer than the calyx, the false septa incom- 

 plete above and ciliate. — Pine woods in the mountains of New Mexico 

 {Greene, Mattheivs) and Arizona {Lemmoti, Jones). 



6. L. KiNGii, Watson, Bot. Fortieth Parallel, 49. — Perennial, fruticose, 

 glabrous and usually very glaucous, a span to a foot high; stems rather 

 thick, cespitose, the striate or somewhat angled branches ascending; 

 leaves rather thick, crowded and somewhat appressed, oblong or spatu- 

 late, subacute, i-nerved. (2X8-10 mm.), larger, more remote and spread- 

 ing above, without stipular glands; flowers rather large, densely corym- 

 bose-paniculate at the ends of the branches ; sepals small, broadly oval, 

 obtuse or taper-pointed, the inner glandular-ciliate, 3-nerved, with the 

 midnerve rather prominent; petals oblong-obovate, entire or slightly 

 crenate, with contracted glabrous claws, 5-10 mm. long, several times as 

 long as the calyx; stamens and pistil two-thirds as long as the petals ; 

 anthers rather large (2 mm. long); styles distinct; capsule ovoid, acute, 

 somewhat longer than the calyx, the false septa incomplete nearly to the 

 base and ciliate. — Mountains of Utah {Watson, Hayden, Hooker d- 

 Gray). Old specimens with widely spreading capsules suggest the fruit 

 of Sedum.
