PlantcB Lindheimeriana. 173 



interrupte multifloris fasciculis approximatis ; bracteis ovatis 

 acuminatis ; calycis tubo valde obliquo postice saccato pedi- 

 cillum bis terve excedente, lobis lanceolatis acuminatis mar- 

 gine albo-villosis, superioribus ultra dimidium coalitis. — 

 Rocky prairies on the Cibolo and Pierdenales, growing 

 sparsely. May, June (in flower.) — Caudex perpendicular, 

 dilated below the summit into a globular tuber, of nearly an 

 inch in diameter. Stem 2 to 3 feet high, simple, or sparingly 

 paniculate at the summit. Lower petioles nearly as long as 

 the leaflets ; the latter 2 or 3 lines wide. Spikes dense, one or 

 two inches long. Flowers apparently pale purple, fully half 

 an inch in length ; the pedicels scarcely a line long. Calyx 

 conspicuously glandular ; the tube remarkably one-sided, 

 nearly straight on the lower side, but strongly gibbous-saccate 

 or almost calcarate on the upper ! The free apices of the 

 nine filaments are very short, all antheriferous ; five of them 

 spatulate, the four intermediate triangular and shorter. 

 Ovary glabrous. Fruit not seen. 



(594.) P. hypogjea, Nutt., var. scaposa : pedunculis petio- 

 los v. folia aequantibus, 1|— 2§ unc. longis. — Stony soil, hills 

 on the Pierdenales, near Fredericksburg. April. (Western 

 Texas, Mr. Charles Wright.) — Tuber globular or pointed 

 upwards, sending forth a slender caudex, beset with membra- 

 nous scales. From the Canadian River we have specimens 

 gathered by Mr. Gordon, which are intermediate, as to the 

 length of the peduncle, between the Texan plant and that 

 described by Nuttall. 



373. P. floribunda, Nutt. in Torr. fy Gray, Fl. 1. p. 

 300. Prairies on Comale Creek. In black, clayey soil, 

 New Braunfels, " growing in patches, many stems from the 

 same base, forming a large and dense bush." June. — May 

 not this rather than P. obtusiloba (of which Mr. Wright has 

 sent characteristic specimens from Texas,) be the P. tenui- 

 jlora of Pursh and Nuttall ?
