Plante Lindheimeriane. 45 
carinatis et impresso-punctatis. — L. Mandanense, Torr. in 
Nicollet, Rep. p. 155, non Hook. — Clayey prairies, near In- 
dustry. April, May. A foot high. Leaves rather scabrous 
above, almost exactly like those of L. longiflorum (L. incisum, 
Lehm.) ; the radical somewhat oblanceolate. Lobes of the 
corolla hirsute on the outside. Except the flowers, the plant has 
wholly the aspect of L. longiflorum ; but the corolla is shorter 
than in L. Mandanense, and entirely destitute of the append- 
ages in the throat, unless their rudiments may be obscurely 
discerned in the sinuses, not opposite the lobes of the corolla. 
279. Evroca sTrictTiIFLora (n. sp.) : cinereo-hirsuta ; cau- 
libus plurimis simplicibus e radice annua adscendentibus ; fo- 
liis pinnatifidis lanceolato-oblongis (seu primordialibus integris 
obovatis), inferioribus in petiolum attenuatis lobis brevibus 
obtusis, superioribus sessilibus lobis lanceolatis acutiuscullis ; 
racemis terminalibus multifloris elongatis arcte secundis, fructi- 
feris strictis ; calycis lacintis spathulato-linearibus, fructiferis 
erectis auctis pedicello appresso parum longioribus ; corolla 
late campanulata calyce sesquilongioribus, tubo obscure 10- 
squamigero ; filamentis pilosiusculis inclusis; ovario 14—20- 
ovulato ; capsula plerumque 12-sperma.— Sandy soil on the 
banks of the Brazos near San Felipe. March. A span high ; 
the whole plant almost hoary with a hirsute pubescence. 
Radical leaves with about 5, the upper cauline with 2 or 3 
pairs of lobes. ‘The erect calyx-segments as well as the pedi- 
cels give the crowded racemes in fruit a very stiff and strict 
appearance. Corolla apparently blue, a little hairy externally ; 
the margin very obscurely erose-crenulate ; the tube furnished 
at the base with 5 pairs of linear and narrow appendages 
which are adherent by the whole margin, so as to form 5 rather 
inconspicuous grooves which alternate with the stamens. The 
corolla is almost an inch in diameter in Lindheimer’s speci- 
mens. ‘lhe same species occurs in Drummond’s Collection 
(3. No. 298) apparently with smaller flowers. 
280. E. parutirtora (n. sp.): pubescens, subcinerea ; 
caulibus e radice annua diffusis ramosis; foliis spathulato-
