that the persistent style of the former is sufficient to distinguish it 

 from the jointed style of the latter, is there not still good ground for 

 suggesting a change in the description of these two species?

Germination of Iris versicolor.— The accompanying figure illus- 

 trates a peculiar mo Je of germination that I have observed this spring 

 in 7>/^ 27^;'i-/V^/(:?;'^ the seeds of which I had planted in a flower-pot 



kept in a rather warm place in the house. The de- 

 scriptions and figures of the germinating seed of Ins 

 which I have seen thus far (cf. Gray, Structural 

 Botany, p. 24, fig. 55) do not agree with my observa- 

 tions, for I do not find mentioned and illustrated in 

 them the long, filamentous connective {cf) between 

 the endosperm of the seed {sd) and what I must call 

 the cotyledon (en). 



The whole process reminds one very much of the 

 germination of Phoenix dactylifera (Sachs's Botany, 

 Eng. edit., 1875, p. 542, fig. 388), but in the case of 

 the Iris the connective is much longer in proportion, 

 and rises, with the first node («), and the first leaf 

 (//"), from one-half to three-fourths of an inch above 



the surface (^/), while the seed {sd) stays behind 

 under ground. 



It would be worth while to ascertain whether this 

 mode of germination is common with Iris versicolor^ 

 or whether, as I suppose, it is abnormal — caused per- 

 haps by the more rapid growth at a higher temperature.

New Station for Corema Conradii, Torr. — Learning that Corema 

 Conradii^ Torr, had been found on Shawangunk Mountain, Ulster 

 Co., N. Y., I went there on the 2d of May to seek it. I found it grow- 

 ing on the crest of the ridge, in a bleak spot npt sheltered by trees; 

 quite plentiful there, but not seen elsewhere, for the two miles that I 



looked for it. 



It is a low bush, much branched, spreading, almost prostrate, with 



erect branches, about 9 inches high, and 20 inches wide across the 



branches, from out to out. 



It is described as dioecious or polygamous. I got 85 specimens, 

 of which were dioecious, 84; monoecious, i; polygamous, o. 



The monoecious specimen had 30 clusters of pistillate flowers 

 near the top, and one cluster of staminate near the base: total clusters 

 on the specimen or branch, 31, I saw no otlier flower in bloom, 

 on the mountain. I found a small form of Aspleniiim montamim^ 

 Willd., from one to one and a half inches high. 



The day was cold, with a high wind and heavy squalls of snow 

 and rain. In some sheltered places, last winter's ice was not all 

 gone. The height of the ridge is about 1,800 feet above tide- water. 

 It was too early for the regular spring flowers in so elevated and ex- 

 posed a place. I was under the impression that the plant was
