180 Rhodora [OCTOBER 
long, pubescent. Nut, maturing the second year, depressed or 
subglobose, slightly broader than long, 10-12 mm. thick, pubescent, 
dark brown, about one third covered by the rather deep flat-bottomed 
cup with thin edge formed of several rows of appressed closely pubes- 
cent silvery brown scales. Aments about 4 cm. long, rather loose. 
Growing on sandy soil near Crestview, Florida, with many other 
oaks. The nut is strongly suggestive of that of Quercus megacarpa 
Ashe! of the same general region, but the leaves of megacarpa are 
much contracted in the middle, and are glabrous beneath. The 
foliage resembles that of Q. arkansana Sarg.? but the petioles are much 
shorter and the upper pair of lateral veins are less prominent and are 
rarely extended as awns. 
Carya ovalis mollis, var. nov. Having the fruit of the type and 
with its red petioles and large leaflets, but the leaflets soft-pubescent 
beneath. Dry crests of ridges, Twin Creeks, Adams County, Ohio. 
For several years various forms of the dwarf rosé-flowered locusts 
(Robinia) of the southeastern United States have been cultivated. 
Many of these forms when cultivated failed to set fruit and if the 
wild plants of these forms fruited it was seldom. A number of 
years ago Meehan noticed this in the case of Robinia hispida L. 
At one time this absence of fruit was thought to be due to failure to 
secure cross fertilization on account of the absence of proper insects 
from plants in cultivation. Subsequently these barren forms were 
regarded as sterile hybrids. The wide and general distribution of 
some of these plants, however, seemed to render this view untenable. 
Later the fact that not infrequently a fruiting form and a barren form 
were widely associated led to the conclusion that both might be forms 
of the same species. Following this idea there were included in the 
description of R. grandiflora Ashe? two plants which frequently grow 
together, one producing fruit, the other apparently barren, but 
connected by a more or less intermediate form. Attempts at cross 
fertilization and two seasons' further study both of wild and culti- 
vated plants indicate that these forms have no such complementary 
relation but are better regarded as distinct species. Similarly the 
form recently described as R. unakae Ashe* was held to be the fertile 
component of R. hispida and the statement made that R. hispida 
freely produced fruit and that plants had been grown from its seed.
