tube, longer and usually reflexed peduncles, and relatively slender and 

 more acute capsules. Like M. latifoliiis, this species is somewhat in- 

 termediate between §§ (Eiioe and Eunanus. 



MiMULUs GRAciLiPES. A delicate annual, 3 to 5 inches high ; stem 

 usually simple, glaudular-puberulent under a lens : leaves about four 

 pairs, very small, seldom exceeding 4 lines in length, sessile, lanceolate, 

 obtusish or scarcely acute, entire or minutely denticulate, the round- 

 ish cotyledonary(?) leaves persisting at base: peduncles springing by 

 pairs from each node, an inch long, filiform, spreading horizontally 

 and gracefully curved upward : calyx oblong-campanulate, a little 

 over 2 lines in length, a line in diameter, the equal teeth slightly 

 spreading, obtuse, strongly ciliate ; corolla rose-purple with yellow 

 markings in the throat, the tube not quite twice the length of the 

 calyx ; limb spreading, 3 or 4 lines in diameter, strongly bilabiate, the 

 upper lip much shorter than the ample 3-lobed lower one : capsule 

 symmetrical, of delicate texture, elliptical in outline, 2 lines in length, 

 included in the scarcely inflated calyx ; seeds obtuse, apiculate at each 

 end. — Collected by Mr. J, W. Congdon, at Mormon Bar, Mariposa 

 County, April, 1889, Near M. ruhellus, Gray, and M. dejlexiis, "Wat- 

 son, but differing from the former in its simple stem, much larger co- 

 rolla, and longer peduncles ; from the latter in the color of its corolla; 

 and from both these and various other related species in its ciliate 

 calyx. 



Aster Engelmanni, Gray, var. (?) paucicapitatus. Slender; 

 stem weak and flexuous : leaves numerous, oblong-elliptic, obtusi?h, 

 apiculate, puberulent above and with scanty traces of tomeutum be- 

 neath, 10 to 15 lines long, a fourth as broad : heads solitary, terminal, 

 or sometimes 3 to 5 ; scales of the involucre more equal and less closely 

 imbricated than in the typical form or other varieties; rays white or 

 pink. — Collected by Mr, C, V, Piper iu the 01ym{)ic Mountains, 

 Washington, September, 1890. This is a very puzzling form and 

 perhaps a distinct species. If, however, Dr, Gray was right in class- 

 ing A. ledophylliis, Gray, and A. Engehnanni, var. glaucescens, as va- 

 rieties of the same species, Mr. Piper's plants, which are in some 

 regards intermediate between these varieties, should probably also be 

 included iu ji. Engelmanni. 



In closing, the writer wishes to express his warmest thanks to Dr. 

 Serene Watson for his kind and ready aid in many points of dillicult 

 classification and perplexiug uomeucluture.
