Muhlenbergia, Volume 7 



That Professor Nelson ascribed to the plant the character 

 "corolla tube not yellow," is quite excusable, as the plants had 

 been through an herbarium fire, and subjected to intense heat 

 as well as water. All our recent collections have a distinct yel- 

 low throat to the corolla. The lobes of the calyx are perhaps 

 better described as elliptical-ovate than ovate. The lobes of the 

 corolla have a blunt notch at the apex. The fruit, which was 

 not present in the type, is 7 mm. long, including the calyx 

 lobes, and densely glandular. The capsule is broadly elliptical, 

 3 mm. long, i mm. wide, with usually two brown, rough, some- 

 what crescent shaped seeds about 2 mm. long. 



Brand, in his monograph of the Polemoniaceae, cites this 

 species among his eight subspecies and varieties of Polemoniunt 

 pulcher7'im.ii7n Hook., and calls it var. Haydeni (Nelson) Brand, 

 with the following synonymy: "Z^. Haydeni Nelson; P. Tevisit 

 Eastwood; P. vtonirosensis {sic\) A. Nelson."

As we were fairly certain that the plant is not the same as 

 P. Hayde7ii^ from the description, we secured one of the co-types 

 through the kindness of Dr. Wm. Trelease, Director of the Mis- 

 souri Botanical Garden. An examinatiou of this sliows us that 

 P. Haydeni is a much larger plant with larger and differently 

 shaped leaves, much larger, differently shaped calyx and corolla 

 lobes, and dissimilar anthers, as mav be seen in the accompanv- 

 fiofure.
