TRELEASE ILICINE^E * CELASTRACE^. 349 



ceolatits of Pursh, I.e. 220, and, presumably, llill, Veg. Sjst. (1770), xvi. 

 pi. 61. — Georgia and Louisiana. 



Regarded by Watson and vSargent as a very doubtful species. My de- 

 scription is based upon rather unsatisfactory specimens from Dr. Chap- 

 man, in the herbarium of Columbia College. If this stands, the Ilex 

 lanceolata of Grisebach, Cat. PI. Cub. Wright. (1S66), 56, may bear the 

 name /. VVrightii. 



NEMOPAXTHES, Raf. — Shrub with slender-petioled nearly estipu- 

 late leaves; flowers 4- to 5-merous; calyx obsolete in the fertile flowers; 

 petals distinct, linear, acute; stamens free. — Journ. Phys. (18 19), 96; 

 Benth. cS: Hook. /. c. 357. 



I. N. Canadensis, DC. — Glabrate; leaves half inch to 2 in. long, el- 

 liptical, often somewhat acute at both ends, mostly mucronate, entire or 

 sparingly low-serrate, finely reticulate-veined; flowers solitary on slender 

 bractless pedicels half inch to i in. long; drupe red, ovoid, styleless, about 

 6 mm. in diameter; nutlets faintly ribbed on the back. — Mdm. Soc. Gen. 

 (1821), 1.450; Watson, Index, i6a. — Canada to the mountains of Virginia, 

 west to Minnesota and Indiana. 



As Vacciniuni mucronaium, L. Sp. (1753), 350, was founded on a fruit- 

 ing specimen of this according to Dr. Gray (Syn. Fl. ii. 20), the attempted 

 change in principles of nomenclature would cause it to bear the name N, 

 mucronata (L.)

This group is somewhat heterogeneous in the sense in which 

 Bentham and Hooker accept it, and especially as it is limited by 

 Baillon (Hist. Nat. des PI. vi.), but there appears to be no very 

 good reason for recognizing the component Tribes as of ordinal 

 rank, 



Etionytnus., which comprises about 40 species, centering about 

 Southern Asia, is represented with us by 4 endemic species rather 

 closely related to those of Europe and Eastern Asia. Like Ilex, 

 it was established, especially in the old world, in the Tertiary age, 

 although it may have originated earlier.* Two common Euro- 

 pean species, E. Europceus and E. latifolms, are said by Sa- 

 portaf to have existed in Europe during the Qiiaternary period. 

 Pollination is effected mainly through the agency of flies and 

 small bees, chiefly the former, which feed upon the readily acces- 

 sible nectar, crossing being favored by protandry in the Euro-
