117. Clintomaparviforn. I^eaves with the margin and keel ciliale ; umhellul© 
mviltiiioie ; flowers ercct ; sepals ungiiiculated ; claws erect; limb rotate; dlsfc

flowered; peduncles unequal, one erect, the other curved ; flowers erect, 
semi-campanvdate ; sepals oblong, acute.— Found with the forejjoinj? ; larger: 
fl;;\vers large ami v. iiite. My genus Clintoma (Amer. Jour, of Sc.) contains now 
four sjiecies ; the other two are CI. muUins ^' Draccna borealis Auct.^ and CI. udo' 
rata, (tlie Convuli. ymbeUida^a of Michaux) ; they afford many varieties. I have 
sent a new moiiagraphy <,f this genus to the same Journal. 
VJi CLASS. PHAMEiiOGVNIA.— 1 HE PHANERIANS. 
SXIII. N. G. Hedtchloe. Flowers capitate, invohicrate, chafTy or paleaceous. 
Chaffs uniflore, glumriceous. (Jlum bivalve ; valves unequal, carinate, the inter- 
nal larger and involving- Stamina two. Ovary pedicellated, elliptical", ^obtuse, 
compressed; one style, two 9tigm.-<s. — The type of this genus is the KyUin^ia 
pumila, which 1 call /fcdychloefm^raiir;, and is found from Illinois to Carolina. 
1 19. Scirpus orff:'a!is. Scapes and leaves cylindrical, smooth ; hstulose verv 
long, acute ; spikes lateral under the apex, glonierated, ovate, sub-sessile ; scale.i 
ovate, mucronate, brown, arachnoidal. — It grows in the creeks and rivers of 
New York and Pennsylvania, rising to five a>Kl £i.\ feet, it is probably the ici 
RicvsCn.<f of OUT botanists, but not the Eviropean and Unnean species. 
VDl CLASS. CRYPTOGYNLA.—THE CRYPTIANS.

IX CLASS. MYCOSIA.— THfi FUNGLiNS. 
!XXIV. N. O. AN-AsTo?iAni.i. Fructincation in- flexuose lamellar eiu*; anar 
fomosed like a net. — This genus will be next to JfLndius and iJen'a/ea -, t-om-, 
species of them may probably belong to it. 
121. Jinastomariaeampaimlata: Siipitated fulvous, ; stipe thick; peridc cr.n"- 
par.ulated ; netted outside, margin erose, insides scaly and dark spotted. — Tii:.'< 
may be the type of the genus. Size fjur or five inches. It grows in the stati oi 
Slew- York.

white above, flattened and reddi.sh brown beneath, with a marginal concentric 
jijrrow — Found on a IJeech tree on the Catskill mountains ; pores unequal, po- 
lygonal, lacerated. Perhaps a new genu.s, Lamy.vis, intermediate between Siso^' 
(iemn and Jio'ctus. 
X CLASS. ALGOSIA—THE ALGL\NS. 
SXVN.fi. Stti'niov. a floating gelatinous and flocose mass, easHy divided 
and homogenous, without any perceptible filaments or organs — A very singular 
genus, nexi to my G. Potavc'ns. It differs from Conferva, which consists of fixed 
lilaments, and Os«7/a«o?7n of interwoven articulattd ones. I could not perceive 
any filaments in it, perhaps a microscope might show some, surrounded by a jelly. 
The itame means Tow in greek. 
124. Siypiiionjintans. Floating, elongated perpendicularly ; amorphous, flos- 
Cose or lacerated ; of a dirty yellowish or brown colour. — Very common on the
