PlantcB Lindheimeriana. 253 



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. Eutoca strictiflora (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 acutiusculis ; 

 racemis terminalibus multifloris elongatis arete secundis, fructi- 

 feris strictis ; calycis laciniis 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. The same species occurs in Drummond's Collection 



* (3. No. 298) apparently with smaller flowers. 



280. E. patuliflora (n. sp.) : pubescens, subcinerea ; 

 caulibus e radice annua diffusis ramosis ; foliis spathulato-
