many respects, and is perhaps the species so named by Muhlen- 
berg in his Catalogue. At the same time it seems to differ 
J. squarrosus in some of its most striking features. In our plant 
the leaves are erect and not spreading ; the anthela is shorter — 
and more corymbose, with an ‘elongated bract. In J. squarro- 
Sus the bracts and margins of the sepals are white, giving a 
marked character to the plant; in J. Greenei all these parts are 
brown. The two species differ also in their capsules ; those of 
J. squarrosus being slightly obovate, and nearly double the size 
of those of our plant. This can hardly be confounded with 
any other of our Junci: ‘The more naked culm at once distin- 
guishes it from the other allied species. 
* Tn 1789 Cutler had distinguished and described Microstylis and Comandra as 
New genera; Orchis fimbriata is referred by him to O. psycodes, L., to which Dr. 
Gray has.recently shown it to belong. ‘An account of the labors of this botanist 
will be attempted on some future occasion.
