Uab. Moist thickets, and low grounds: frequent. FL August-Sept. FY. Octo 

 Obs. This species, also, presents some varieties— ont 1 have seen, from New 

 Jersey, with the scape quite leafy, the leaves fleshy. These are all the known 

 species in the U. Slates. 



l>. Anther terminal, opercular or opening like a lid. 



400. ARETHUSA. /,. JfiUU Gen. 715. 

 [Poetically named from Arethusa, a nymph of Diana.]

 and cucullate. Lip united at base with the column, deflected at apex, 

 bearded internally. Pollen angular.

Bulbous Aretiiusa. 



Root perennial, coarsely fibrous, bearing a globose tuber at the bas/of the 

 scape. Leaves mostly 0. Scape 3 or 4 to 9 inches high, striate, smooth, bearing 3 

 or 4 loosely-sheathing scales ;-from the upper sheath there often finally proceeds 

 a linear-lanceolate, cuneatc, or spatulalc-linear acute nerved lea/. Flower mostly 

 solitary, terminal, largo, fragrant, deep bright purple, with 2 unequal bracts at 

 basc,-one of the bracts ovate and amplexicaul, the other sublinear, or sometimes 

 short and lance-ovate. Segments of the perianth lanceolate, 5 of them conniver.t, 

 vaulted or curved forward, connate and tapering below ; lip broad, conduplicato 

 below, the apex spreading, deflected, wavy and crcnulatc on the margin, bearded 

 or crested, and somewhat spotted with yellow, on the inner or upper surface. 

 Column shorter than the Up. 

 Uab. Sphagnous swamps ; Great Valley: rare. Fl. May. Fr. 



Obs. This beautiful little plant is very rare here. It has, however, been found 

 by Mr. Joseph Jacobs, and subsequently by 1). Townskkd, Esq. Dr. Bigelow 

 remarks, that the upper sheath on the scape, finally "expands into a short lance- 

 olate leaf"; but, as fur as I have observed, there is a leaf finally protruded from 

 the upper sheath, which is quite distinct from the sheath itself. This is the only 

 species of the cenus, as it is now restricted. 



401. POGONIA. Juss. jYutt. Gen. 712. 

 [Greek, Pogon, beard ; in allusion to the bearded lip of the flower.] 



Perianth with the segments distinct. Lip sessile, with a beard-like 

 crest on the inner or upper side. Pollen farinaceous. 



1. P. oprioglossoires, Br. Scape with an oval-lanceolate leaf near 

 the middle, and a foliaceous bract near the flower ; segments of the
