DTDYNAMIA AXGIOSPERMIA 375 



>. How, often tinged with brownish purple, smooth; galea truncate, with a m 

 cccustooih terminating each margiu. Style a little cxsorled. Capsule compres- 

 sed, oblique and a little gibbous at base, with a lance-oblong or ensiform acumin- 

 atum 1 third to half an inch or more in length. Seeds oval, angular. 

 Hab. Woodlands, thickets, and knolls: frequent. FL May. /V.June. 



Obs. This plant is variable, in size and appearance, in different localities ; and 

 I am now inclined to think the P. gladiata, of Authors, is nothing more than a va- 

 riety. It is doubtful whether any other species have been found in the U. States, 

 —though several are enumerated in British America.

Crimson Euchroma. Vulgo — Painted cup. Red Robin. 



Root perennial ? (annual or biennial, Null. Ell. biennial, EkU.). Stem 9 to 18 

 inches high, erect, simple, sometimes several from the same root, pubescent, often 

 dark purple. Leaves 1 to 2 inches long, and I eighth to half an inch wide, 3-nerved, 

 I ubescent ; the radical ones often spatulatc-linear, entire on the margin, and in- 

 cised at apex ; the stem-leaves linear, with 2 or 3 very long narrow linear divari- 

 cate or diverging segments on each side ; ihe Jlot at leaves, or bract V, cuneate, tri- 

 fid, villose and ciliate, crowded at the summit of the stem, the segments crimson. 

 Calyx with the tube ventricose, membranaceous, villose ; segments linear-oblong, 

 retuse, tipt with crimson. Corolla dull greenish yellow ; upper lip 2 or 3 times as 

 long as the lower, roughish-pubescent externally. Stamens shorter than the up- 

 per lip of the corolla ; anthers cohering, or sometimes free. Style exseried ; stig- 

 ma emarginate. Capsule about half an inch long, elliptic-ovate, slightly oblique, 

 smooth, dark brown; valves grooved opposite the dissepiment; the dissepiment 

 separating into 2 plates. Seeds minute, somewhat pyriform, coated with a reticu- 

 lately rugose-pitted arillus-like membrane. 



Hab. Low grounds ; margins of swamps, &c. frequent. F7. April— May. Fr. June. 



Obs. There is a variety of this (var. pollens, Pursh),— with the bracts colored 

 yellow, and the whole plant of a pale yellowish green,— which I have seen in the 

 meadows at Downingtown ; but it is somewhat rare. Mr. Nuttull describes 9JW 

 other species of this genus m the U. 6:atcs, far west.
