enberg (Cat. 1813) and V. bicolor of Pursh (Fl. 1814), who evident- 

 ly regarded it as native and for that reason, perhaps, a distinct species. 

 Even if further comparison with European specimens should prove 

 the determination of Torrey and Gray correct, its claims to a place in 

 our indigenous flora seeni to me very strong. In Pennsylvania it is 

 widely diffused, but rare, yet abundant wherever found. It occurs in 

 grassy meadows and on rocky slopes, remote from dwelhngs and never 

 in cultivated grounds. Its entire behavior is that of a native, and 

 hence unlike that of V. tricolor oi the gardens, which, though it comes 

 up from self-sown seeds, soon disappears, when not reinforced by 

 fresh plantings, and shows no disposition to spread beyond cuhure. 

 Mr. Reverchon. in the last number of the Gazette, reports it from 

 Dallas county, Texas, and says: *' I am satisfied it is native. I have 

 met it in large patches in remote woods and prairies, sometimes very 

 /rtir from settlements " To this I may add the fact that it has also 

 been collected in Colorado by Mr. Wm. A. Henry, who thus wrote 

 me Aug. 29, 1876-" I send you more of the violet. It grows on a 

 warm, dry slope at the mouth of Boulder Canon, in a rather inaccess- 

 ible place. I have seen a few stalks further up the canon. It blooms 

 very early, along with Leucocrinum montanuin, so that it has probably 

 escaped the notice of other collectors. I gathered it three years 

 before in the same ])lace. It. could have been introduced, but I great 

 ly doubt that seeds of recent introduction could have reached the 

 spot where I found these plants." 



I may here mention another addition to the flora of Colorado. 

 Aubrey H. Smith, Esq., has kindly given me specimens of Goodyera 

 repens, P.. Br., collected by him on Pike's Peak, Aug. 1878. —Thos.

Lepidil'm campestre, Linn. — Last September as I was just com- 

 ing out of the hay fever, a farmer brought me a package of what he 

 said was now becoming a troublesome weed. I instinctively smelled 

 of the plant and brought hack some decided sym])toms of my malady. 

 The weed proved to be Z. cam[yestre. As this has hitherto been a rare 

 plant, it is of interest to know that with us it is no longer so. But 

 this crucifer has struggled hard to attain its acclimatization. An ad- 

 venturer from Europe, it came, as I believe, from Great Britain, 

 where it was accustomed to a mild and humid climate, hence, though 

 a great seed bearer, ere it could become prolific of individuals it had 

 to struggle through several generations of years in a climate involving 

 extremes so o|)i)Osile to the conditions of its native land. — S. Lock

ZosrERA .MARiN.v, L. — .\. Euglcr, in a recent number of the Bot- 

 anische Zeifung, has published some interesting observations concern- 

 ing the " Eel grass," so common in the bays of our own coast. His 

 observations relate chiefly to fertilization and growth. The following 

 is an abstract of his paper from a late number of Nature. 



At first the thread like stigma lies on the neighboring anther lobes.
