the axils of the veins, such as are characteristic only of shwmardit. 
The fruit while only slightly larger than that of phellos has a much 
deeper and thicker cup with large scales, W. W. A. No. 1080. The 
cups in this collection are not quite so pointed at base as figured by 
Houba, but there is considerable variation in shwmardii in this respect, 
and there is a yet wider variation in hybrids. Houba’s reference to 
the tufts of pubescence in the axils of the veins points only to shumardti 
as one parent; while only phellos as the other parent would determine 
glabrous foliage in connection with the narrow outline. 
ACER BARBATUM sinuosum n. c. A. sinwosum Rehd., T. and S. 2: 
255 (1913). This form has been found in the Wichita Mountains, - 
Comanche County, Oklahoma, thus extending its distribution more 
than 300 miles north of the type and hitherto only recorded locality. 
Rehder has recently reduced it to a varietal status and the material 
from the Wichita Mountains confirms this disposition by more clearly 
indicating the relationship of simuosum to barbatum. In the Wichita 
Mountain specimens the leaves are glaucous beneath as in barbatum. 
and have the customary leaf form of barbatum, there being three 
prominent lobes with parallel sides, 3-notched at the tips. The 
first pair of nerves also rises from the petiole and not from the second 
pair. However, on these same trees the upper leaves have 3 subentire 
triangular lobes as described for simuosum. The only difference be- 
tween sinuosum and barbatum Mx. (A. floridanum (Chap.) Pax.) is the 
exposure of the nerves of the second pair of lobes at the point where 
they Join the petiole and the somewhat stouter bright red-brown twigs. 
QuERcus NIGRA heterophylla n. c. Q. aquatica var. Aiton, Hort. 
Kew. Ed.2,5:290 (1813). This differs from the type only in theleaves 
especially those on vigorous shoots, which are deeply and irregularly 
3-5-lobed, some of the divisions being ligulate, 5-8 cm. long, 1-2 cm. 
wide, acute obtuse or even rounded at the ends. On the Atlantic 
Coast an occasional shoot or rarely a tree occurs having such foliage. 
In western Louisiana and eastern Texas, however, many trees occur 
on which most of the foliage is of this character. It is with some doubt 
that Aiton's name is taken up but his description seems to apply 
very well to this form.
