Planted Lindheimeriana. 155 



LINACE^E. 



f Linum Boottii, Plonchon 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. Boottii, Y- rupestre ; caulibus gracilentis ; foliis 

 lineari-subulatis ; sepalis paulo latioribus ; capsulis minoribus. 

 — L. rupestre, Lindheimer in sched. New Braunfels, with 

 Cereus ca;spitosus, growing sparsely on rocky soil or in crev- 

 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. multicaule, 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 £- 1 inch long, 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, 2-2£ lines in diameter. — The 

 seeds of both forms are absolutely identical, so that the difference 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 a have an 

 acidulous, and those of (9 an insipid, mucilaginous taste.

4. P. pilosa. L. : sepalis lineari-oblongis, petalis ovato-oblongis obtusis retusis s.

 seminibus minutis nigris opacis minute tuberculatis. Texas, New Mexico, Mexico, 

 etc. — 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. 



5. P. Gilliesii, Hook.: sepalis orbiculato-ovatis petalis orbiculato-obcordatis 

 ter quaterve brevioribus; staminibus numerosissimis (60) sligmatibus sub-5 exsertis 

 longe brevioribus ; seminibus paulo majoribus tuberculatis cinereis nitentibus.— Com- 

 mon in cultivation, and here and there almost naturalized ; originally from Chili. 

 Flowers 20 - 24 lines in diameter, open from 8 or 9 to 2 or 3 P. M. in sunshine. Stig-
