) 



pistaciajfolia.) A well cliaracterized species, easily known 



by the small fruit (scarcely 8 lines long,) which is broad in proportion and not contracted at the 

 base. The leaflets are narrower and entire in Mr. Wright's specimen^ while in Dr. Parry's 

 they are broader and mostly serrate.

foliolis uni- 



jugis ovatis vel obovatis integerrirais aut versus apicem crenato-serratis basi in petiolulum atte- 

 nuatis ; samaris lineari-oblongis emarginatis. Sterile mountains a few miles south of the Mexi- 

 can boundary line, in Lower California, July (in fruit) ; Parry, A shrub or small tree growin"- 



in clumps, sometimes 20 feet high, with a trunk three inches in diameter. Leaflets never more 

 \WL than a single pair and a terminal one ; sometimes^ indeed, reduced to the single terminal one ; 



the largest scarcely more than an inch long ; common petiole channelled above. Flowers not 

 J HI known. Fruit in a loose cymose panicle, about three-fourths of an inch long, and 2-^- lines 



wide, (in one specimen 3 lines wide,) only a little contracted at the base. As the flowers of 

 this ash are unknown, and the fruit of F. dipetala has not yet been seen, it remains uncertain 

 whether they are distinct, or are only extreme forms of one species. 



FoRESTiEKA PHiLLYREOiDES. Piptolepis phillyrcoides, Benth. PI. Hartiv, p. 29. Var. spathu- 

 LAEFOLiA : foliis spathulatis subcoriaceis. Near Monterey, Neuvo Leon and plains west of San 

 Pablo ; Gregg, A shrub about 5 feet high. Not yet found in fruit. There can be no doubt 

 of the identity of Piptolepis and Foreetiera. The flowers of botb agree in all essential characters. 

 We place this genus in Oleace^e where w^e have for many years regarded it as belonging, adopt- 

 ing the view of Richard, who more than half a century ago, said of it ^^ genus affine Chionan- 



more recently Tulasne.t 



tho/'* Other authors have pointed out its affinity to Oleaceae; but 

 has clearly shown that this is its true place.

Sp. 4, 711 ; Pur&h^ FL 2, p. 22, Borders of the Rio Grande in w^estern Texas, and in 

 Chihuahua. Leaves about an inch long, obovate or obovate-oblong, mostly obtuse, abruptly 

 narrowed at the base with a short petiole, slightly serrate, when young pubescent, but at len<:^tli 

 nearly glabrous except along the midrib and on the petioles. Fruit oblong, about 4 times 

 longer than the pedicels^ dark blue, the pulp rather thick and sweetish. Nut nearly even. 

 This is not an uncommon plant in Florida, and on the upper waters of the Red and Arkansas 

 rivers. Michaux has incorrectly described the leaves as vei^y entire, 



FoRESTiEKA RETICULATA (n. sp.): foliis ovatis ramulisque glabris acutis vel acuminatis sub- 

 coriaceis prominente reticulato-venosis denticulato-serratis subtusporulo is ; cymulis simplicibus ; 

 % fructibus ovalibus, obtusis apiculatis pedicellis \ longioribus. Crevices of rocks and in ravines 



near the Pecos, on the Rio Grande; Sehotl, Ravines near White Oak Creek; Bigelow, 

 Western Texas; Wriglit^ No. 565. Branches glabrous, but dotted with minute whitish warts. 



L 



Leaves 1-1^ inch long, acute at the base, the veins strongly reticulated, especially (in the dry 

 specimens) on the upper surface ; the midrib very slightly pubescent underneath, Staminate 

 flowers in small simple cymules with short pedicels. Fertile cymules 3-5 flowered. Fruit about 

 3 lines long, very dark purple, with a thin sweet pulp, sometimes 2-celled and 2-seeded. Nut 

 oblong, the shell thin and fragile, marked with prominent longitudinal veins. Seed conformed 

 to the cavity of the shell ; testa thin pale brown, slightly sulcate longitudinally. F. porulosa, 



• Forestiera differs from Chionanthus chiefly as from Fraxinus ornu5.
