546 MONOECIA POLYANDRIA 



Nab. Moist woodlands : frequent. Fl. May. Fr. October* 



Obs. This seems to bo somewhat intermediate between C. alba, and one of th 

 Yaricties of C. parcina ; and is, perhaps, a good species ; though Muhlenberg made 

 t a var. of C. albaf Xutt.-a.nd Barton considers it rather as a variety of C. sulcata, 

 Mutt. 



3. C. tohbktosa, JSTutt. Leaflets mostly 7» oblong- and obovate- 



lanceolate, acuminate, slightly serrate, mu^hish-pubescent beneath; 



amentstomentose; fruit ovoid, or elliptic-oblong ; pericarp very thick; 



nut somewhat 6-angled, the shell thick and very hard. Beck, But.

StemQO to SO feet high, and IS inches to 2 feet in diameter, the bark smoothish, 

 or with the fibres closely interlocked. Leaflets generally in & pairs, with a ter- 

 minal odd one, 3 nr 1 to 8 inches long, and an Inch and half to 3 inches wide (the 

 2 lower pairs considerably smaller than the others), varying from lance-ovate to 

 obovate-lanccolatc, acuminate, serrulate, smoothish above, clothed with a rough- 

 ish stellate pubescence beneath, and also sprinkled with very minute dark-purple 

 particles among the pubescence,-— the lateral leaflets sessile, obtuse and rather 

 unequal at base, the terminal one tapering and acute at base, on a short petiole ; 

 common petiole 4 to 8 or 9 inches long, very pubescent. Anient* termite, 4 to 6 or 

 7 inches long, filiform, pubescent, with hairy brads at base ; scales 3. parted, the 

 lateral segments obliquely lance-ovate, the middle one much elongated, linear, 

 hairy. Pistillate flowers terminal, mostly in pairs, sessile on a short thick brae- 

 tcate common peduncle ; segments of the perianth lanceolate ; ovary very pubes- 

 cent. Fruit ovoid, or oblong-oval, large (often 2 inches or more in length, and an 

 inch and half in diameter); pericarp thick, opening by 1 valves more than half 

 way to the base ; nut somewhat 6-angled near the apex, the shell very thick and 

 hard. 



Ilab. Rich woodlands: common. Fl. May. Fr. October. 



Obs. This species, also, presents some varieties— one of which has a larrc 

 elliptic or ol>ovoid-oblong fruit. There is a variety of it (var. maxima, Xvtt.), * iih 

 still larger fruit, grows along the Perkiomen creek, In Montgomery County ; and 

 may, perhaps, yet be found along the Schuylkill, in this County. The wood of 

 this species is white to the heart, and is celebrated hr its excellence as fuel, It 

 is replete, in summer, with a sweet syrup-like sap,— and when cut in that season, 

 is much preyed on by worms. 



4. C. roHcixA, JVfy# P Leaflets about 7, lanceolate, acuminate, serrate, 

 smooth ; fruit pyriform, or subglobosc ; pericarp thin; nut smooth and 

 hard. Beck, Bot. p. 336.
