THREE-WINGED ASH. 
is unknown, but the figure and description may probably 
serve to recognise it and lead to further inquiry. 
The branches are smooth and remarkably slender, the 
buds small, yellowish-brown and pubescent. The leaves 
are half a foot or a little more in length, with 5 to 7 lan- 
ceolate leaflets, which are 2 to 2\ inches long by about f of 
an inch wide, acuminated with a slender point, and much 
attenuated below, with rather long pedicels ; they are 
opaque, smooth and green on both surfaces, except a 
slight trace of pubescence alongside of the mid-rib, and 
slenderly serrated on the margin ; the petioles are remark- 
ably long, and the distance between the pairs of leaves 
very great ; but the most characteristic distinction claimed 
for this species is in the inflorescence of the fruit-bearing 
plant, which consists of 2 or 3 remote pairs of racemes, 
each being quite simple or unbranched, terete, and pro- 
ducing only 2 or 3 samaras or capsules in place of the 
usual trichotomous and compound cluster. 
The samara is about 1J inches long, lanceolate, obtuse, 
and entire, attenuated and cylindric at the base, and with- 
out any proper calyx, there being a mere margin of junc- 
tion with the pedicel.
