VI CLASS. GYMNOGYNIA.— THE GYMNOGYNES. 



117. CUntonia parviftora. Leaves with the margin and keel ciliate ; umbellule 

 multiflore ; flowers erect ; sepals unguiculated ; claws erect ; limb rotate ; disk 

 oboval, obtuse. — On the Alleghany mountains in Maryland, a small species with 

 white inodorous flowers. 



118. CUntonia pbdanisia. Leaves ciliated only in the margin ; umbellule 2-S 

 flowered ; peduncles unequal, one erect, the other curved ; flowers erect, 

 semi-campanulate ; sepals oblong, acute. — Found with the foregoing ; larger : 

 flowers large and white. My genus CUntonia (Amer. Jour, of Sc.) contains now 

 four species ; the other two are CI. mutans ( Dracena borealis Auct.y and CI. odo- 

 rata, (the Convall. umbellulata of Michaux) ; they afford many varieties. I have 

 sent a new monography of this genus to the same Journal. 



VII CLASS. PHANEROGYNIA.— THE PHANERIANS. 



XXIIL N. G. Hedychloe. Flowers capitate, involucrate, chaffy or paleaceous. 

 Chaffs uniflore, glumaceous Glum bivalve ; valves unequal, carinate,. the inter- 

 nal larger and involving. Stamina two. Ovary pedicellated, elliptical, obtuse, 

 compressed ; one style, two stigmas. — The type of this genus is the Kyllingia 

 pumila, which I call Hedychloe fragrans, and is found from Illinois to Carolina. 



119. Scirpus orgyalis. Scapes and leaves cylindrical, smooth; fistulose very 

 long, acute ; spikes lateral under the apex, glomerated, ovate, sub-sessile ; scales 

 ovate, mucronate, brown, arachnoidal. — It grows in the creeks and rivers of 

 New York and Pennsylvania, rising to five and six feet. It is probably the Sc. 

 lacustris of our botanists, but not the European and linnean species. 



VIII CLASS. CRYPTOGYNIA.— THE CRYPTIANS. 



120. Poly podium erosum. Stem filiform and smooth ; frond pinnated ; folioles 

 pinnatifid ; pinnules erose, obtuse, notched, thin and smooth ; nerves flexuose ; 

 sores scattered, rounded, unequal. — A small species, six inches high at utmost, 

 with a short frond ; it grows on rocks in the knob-hills of Kentucky. 



IX CLASS. MYCOSIA.— THE FUNGIANS. 



XXIV. N. G. Anastomaria. Fructification in flexuose lamellar veins ; anas- 

 tomosed like a net. — This genus will be next to Merulius and Dedalea; some 

 species of them may probably belong to it. 



121. Anastomaria campanulata. Stipitated fulvous, ; stipe thick ; peride cam- 

 panulated ; netted outside, margin erose, insides scaly and dark spotted. — This 

 may be the type of the genus. Size four or five inches. It grows in the state of 

 New- York. 



122. Anastomaria dimidiata. Sessile, dimidiated, embricated, wrinkled above 

 and fulvous with brown or black zones, netted beneath ; veins often bifid near the 

 margin. — Near Catskill, state of New- York. It may be the type of a sub-genus 

 Campsilicus. 



123. Sisostrema globularis. Stipe lateral, exceedingly short : peride globular, 

 white above, flattened and reddish brown beneath, with a marginal concentric 

 furrow — Found on a Beech tree on the Catskill mountains ; pores unequal, po- 

 lygonal, lacerated. Perhaps a new genus, Lamyxis, intermediate between Sisos- 

 trema and Boletus. 



■ X CLASS. ALGOSIA.— THE ALGIANS. 

 XXV N. G. Stypnion. A floating gelatinous and flocose mass, easily divided 

 and homogenous, without any perceptible filaments or organs — A very singular 

 genus, next to my G. Potarcus. It differs from Conferva, which consists of fixed 

 filaments, and Oscillatoria of interwoven articulated ones. I could not perceive 

 any filaments in it, perhaps a microscope might show some, surrounded by a jelly. 

 The name means Tow in greek. 



124. Stypnion fluitans. Floating, elongated perpendicularly ; amorphous, flos- 

 cose or lacerated ; of a dirty yellowish or brown colour. — Very common on the 

 surface of the Ohio in Summer, having the appearance of pieces of ropes or oak-, 

 um. It smells like Conferva.
