Wright,) (mixed in my set with F. pistaciwfolia.) A well characterized 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. As specimen, while in Dr. Parry's 
they are broader and mostly serrate. 
FRAXINUS DIPETALA, Hook. & Arn. Bot. Beech. р. 362, 4. 87. Var.? TRIFOLIOLATA : foliolis uni- 
jugis ovatis vel obovatis integerrimis 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, іп Lower California, July (in fruit) ; Parry. А shrub or small tree growing 
in clumps, sometimes 20 feet high, with a trunk three inches in diameter. | Leaflets never more 
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 
known. Fruitin a loose cymose panicle, about three-fourths of an inch long, and 24 lines 
wide, (in one specimen 3 lines wide,) only a little contracted at the base. As the flowers of 
thisash 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. 
FORESTIERA PHILLYREOIDES. Piptolepis phillyreoides, Benth. Pl. Hartw. p. 29. Var. SPATHU- 
LAEFOLIA: foliis spathulatis subcoriaccis. 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 Forestiera. The flowers of both agree in all essential characters. 
We place this genus in Oleaceæ where we 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- 
tho."* Other authors have pointed out its affinity to Oleaceae ; but more recently Tulasne.+T 
has clearly shown that this is its true place. 
FORESTIERA LIGUSTRINA, Poir. Enc. Suppl. 2, p. 664. F. pubescens, Nutt. in Trans. Amer. 
Phil. Soc. (n. ser.) 5, p. 177. Adelia ligustrina, Micha. Fl. 2, p. 224. Borya ligustrina, Willd. 
Sp. 4, T11; Pursh, Fl. 2, р. 22. Borders of the Rio Grande in western 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 length 
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 very entire. 
FORESTIEkA RETICULATA (n. sp.): hse en URAR glabris acutis vel acuminatis sub- 
coriaceis prominente reticulato-venosis denti btus porulosis ; cymulis simplicibus ; 
fructibus ovalibus, obtusis ЭКИНИ pedicellis 4 longioribus. Crevices of rocks and in ravines 
near the Pecos, on the Rio Grande; Schott. Ravines near White Oak Creek; Bigelow. 
Western Texas; Wright, No. 565. Branches glabrous, but dotted with minute whitish warts. 
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 suleate longitudinally. F. porulosa, 
* Forestiera differs from Chionanthus chiefly as from Fraxinus ornus.
