536 MONOECIA POLYANDRIA 



elliptic-lanceolate, acuminate, obliquely sinuate-dentate, the teeth nearly equal 

 rather acute, callous at the apex, and along the whole margin of the leaf, ihe upper 

 surface smooth and yellowish green, the under surface finely pubescent} whitish 

 or cinereous ; petioles half an inch to an inch, or inch ami quarter, in length, 

 Aeorn small, roundish-ovoid, in a pubescent bowl-shaped cup, which embraces i 

 third of the acorn, and is sessile, or often on a short peduncle. 



Nab. Great Valley, near Brooke's Mill : not common. Fl. May. Fr. October. 



Obs. This was collected, in 1835, at the above locality, by Mr. Joshua Hoopks 

 — who also found apparent varieties of it on the South Valley hills. The leaves 

 are sometimes remarkably long and narrow ; but they generally have a striking 

 resemblance to those of the Chesnut tree. The fruit is said lobe more sweet and 

 nutritious than thai of any other species. 



12. Q. Chinquapin, JMx. Leaves obovate, and lance-oblong, obtuse 



or acute, coarsely and often obsoletely sinuate-dentate, acute at base, 



minutely pubescent and glaucous beneath; cup hemispherical; nut 



ovoid. Jteck, hot. p. 331.

CiriNauAPix Qubucus. Vulgd — Dwarf Chcsnut-Oak. 



Stem 2 to 4 or 5 feet high, slender, and much branched. Leaves 2 or 3 to 5 or 6 

 inches long, and I to 3 inches wide, varying from broad-obovate and obtuse, 

 to lance-oblong and acute, more or less dentate, the teeth mostly obtuse, with a 

 callous tip, often nearly obsolete, or the margin merely repand, cuneately taper- 

 ing and acute at base, smooth above, minutely pubescent and bluish-glaucous 

 beneath; petioles 1 fourth to half an inch long. Acorn small, ovoid, in a sessile 

 bowl-shaped cup. 



Ifcb. Sterile, slaty hills : frequent. Fl. May. .FV. October. 



Obs. There appears to be two varieties of this ;— the leaves of one looking 

 like a dwarf specimen of Q. montana,— and of the other, like a miniature Q. Cu- 

 tanea. This grows abundantly in company with the Black Scrub-Oak ; and, like 

 It, is a sure indication of a sterile soil. They both, however, produce great quan- 

 tities of fruit. Twenty three or four additional species are enumerated in the U. 

 States.

 [Named from Castanea, a city of Thessaly,— famed for Chesnuts,] 



Polygamous : Stamixatb Fl. numerous, interruptedly clustered in 

 very long cylindric Amenta. Perianth 5 or 6-parted. Pistillate 

 Fl. usually 3, within an ovoid squamose, or muricate, involucre. Pe- 

 rianth urceolate, 5 or 6-cleft, having the rudiments of 10 or 12 abor- 

 tive stamens. Ovary incorporated with the perianth ; stigma pencil* 

 form, exserted, cartilaginous and rigid. Nut* 1 to 3, included in the 

 enlarged echinate 4-lobed involucre.
