180 JVo/ice of some rare Plants of JS^ew England, 



the decurrent mid-rib and niargiiis of the leaves. Leaves about an 

 inch long, clasping, the lower ones oval, obtuse, the U|)])er ones lan- 

 ceolate, acute, both with a minute point. Flowers sessile, some in 

 the forks, but mostly on the sides of the long branches. Divisions of 

 the calyx linear, acute, erect, four lines long. Corolla eight lines 

 long, slender, the tube contracted at the neck below the mouth, the 

 lobes spreading, ovate, oljtuse. Stamens from the neck of the tube, 

 extending rather beyond the base of the lulies. Anthers linear-ob- 

 long, at lirst erect, but afterwards twisting outwards. Ovary lance- 

 olate, terete, half as long as the calyx. Style filiform, shorter than 

 the stamens. Stigma dilated, roundish, and deejdy bilabiate. Leaves 

 rather fleshy, pale green. Corolla rather pale rose, the tube nearly 

 white. Anthers yellow. The whole plant very smooth, and intense- 

 ly bitter, like tiie rest of the genus. 



On the sandy margins of the sea shore, Nantucket, where I found 

 it in September, 1829. Dr. Pickering informed me that he found it 

 a year or two before, on the coast of Maryland. 



Potaniogeton Robbinsu. 



Descr. — Leaves lance-linear, sheathing the stem with the adnate 

 stipules, the lamina auriculale at base, the margins finely ciliate- 

 serrulate. Stem long, with long branches, the leaves rather crowd- 

 ed, 2 — 4 inches long, 3 — 4 lines wide, somewhat two-ranked, green, 

 many-ribbed, acute. Sheathing base of the leaves half an inch long, 

 adnate to the stij)ule, the free part of which is produced about half 

 an inch above, and is membranous, white, and somewhat lacerate. 

 Spikes oblong. Flowers rather small. The ciliate serratures are not 

 seen distinctly without a lens. 



This curious species was found in Pondiciierry pond, JefTerson, 

 N. H., by Dr. Robbins, in 1829; and by myself, in the same year, in 

 ponds in Wenham, Mass. 1 have since seen it in ponds in Plymouth, 

 and I have little doubt that it is common, but probably confounded 

 with P. zosterilolius or compressus.

 This long lost species was found before 1829, by T. A. Greene, 

 Esq., at Nantucket, und published in Hitchcock's Catalogue, under the 

 name of S. stellaris. It exactly agrees wiih the descrijition of Lin- 

 naeus, who received his specimens from Kalm. Though it resembles 

 S. stellaris, it seems abundantly distinct in its leaves dilated, not nar- 

 rowed at the base, and in the linear subulate, almost filiform divis- 

 ions of the calyx, which are frequently as long as the corolla. The 

 yellow star, also, is destitute of the deep red angular border of stella- 

 ris, it being only indistinctly bordered with faint brownish purple. 

 The flowers are almost always five-parted, and the corolla is deep 

 bright rose. 



In moist hollows in Squani, Nantucket, in Mr. Greene's locality, 

 September, 1829.
