Plante Lindheimeriane. 155 
LINACEZ. 
+ Linum Boorrn, Planchon in Lond. Jour. Bot. 7, p. 
475. Upper Pierdenales, sparsely in sandy prairies—The 
specimen is entirely in fruit, and has lost nearly all its leaves. 
Some remarks on this species will be found under No. 581. 
337. L. Boorru, 7. RUPESTRE ; caulibus gracilentis; foliis 
lineari-subulatis ; sepalis paulo latioribus ; capsulis minoribus. 
—L. rupestre, Lindheimer in sched. New Braunfels, with 
Cereus cespitosus, growing sparsely on rocky soil or in crey- 
ices of naked rocks. May.— Stems several, from a firm, 
probably not really perennial root, very strict and slender, 
a foot or more high. Petals three or four times the length of 
thelanceolate-ovate, cuspidate, and glandular-ciliate sepals. 
338. L. mutricauLe, Hook. in Torr. & Gr. Fl. 1. p. 678; 
Planchon in Lond. Jour. Bot. 7, p. 185. Upper Pierden- 
ales; socially in naked, clayey places in open oak woods. 
October; mostly in fruit. Flowers small, yellow. Styles 
united almost to the summit. Branches clothed with the 
minute lanceolate-subulate leaves quite up to the flower; the 
cending, very much branched. Leaves 3-1 inchlong, 1-3 lines wide. Flowers 4-6 
lines in diameter, very pretty in the larger forms, open from 8-9 o’clock, A. M. (St. 
Louis, August); earlier than any other species. Capsule with the wing, which is 
formed by the enlarged base of the deciduous calyx, 2-23 lines in diameter. — The 
seeds of both forms are absolutely identical, so that the difierence in the number of 
stamina and stigmata, and in the size and color of the flower, cannot constitute them 
distinct species, as Mr. Lindheimer suggests. He adds that the leaves of @ have an 
acidulous, and those of # an insipid, mucilaginous taste. 
*** Teretifolie: ad axille pilose; caule tereti; foliis plus minus teretibus, basi 
paulo productis ; sepalis membranaceis ecarinatis cum operculo capsule mature de- 
ciduis ; petalis violaceis; capsulze margine circulari tumido. 
4. P. pitosa, L.: sepalis lineari-oblongis, petalis ovato-oblongis obtusis retusis s. 
emarginatis duplo brevioribus; staminibus 15-25 stigmatibus 5-6 subzequantibus; 
seminibus minutis nigris opacis minute tuberculatis. Texas, New Mexico, Mexico, 
ete.— Flowers open from 9-11 or 12 o'clock in bright sunshine, 4-5 lines in di- 
ameter: stigmata glandular, hairy on the margins only, purple. 
5d. P. Gituresu, Hook.: sepalis orbiculato-ovatis petalis orbiculato-obcordatis 
ter quaterve brevioribus; staminibus numerosissimis (60) stigmatibus sub-5 exsertis 
longe brevioribus ; seminibus paulo majoribus tuberculatis cinereis nitentibus.—Com- 
mon in cultivation, and here and there almost naturalized; originally from Cuili. 
Flowers 20 - 24 lines in diameter, open from 8 or 9 to 2 or 3 P. M. in sunshine. Stig-
