The title of this attractive book may mislead some non-dendrologists and non-taxonomists into missing it. It is the geographical and ecological introduction to what will presumably be a more orthodox account of the tree species of the area.

One of the most notable books on eastern trees and shrubs to appear in recent years is Brown and Brown’s authoritative reference work, just off the press. The two authors (no re lation to each other) have spent many decades of study of the subject: field exploration, arboretum culture and observation, herbarium and library study, and have taught botany to hundreds of college students at the University of Maryland and at Frostburg State College. It may well be said that the statements made in the book have been tried and tested most thoroughly.
Willem Meijer is a relatively new member of the faculty of the School of Biological Sciences of the University of Kentucky but he is already becoming quite familiar with the wild flora and is actively engaged in an effort to make it better known to the citizens of the State. In a recent article in this journal (Vol. 35, pp. 161-176. 1970) he pointed out features of the vegetation as a field for research and teaching.
While recently identifying some plants collected in the Potomac River Valley in 1969, I came across a depauperate specimen of Hypericum mitchellianum Ryd berg. Although the leaves and stem of the plant are smaller than usual, the measurements of the capsules and styles agree with thos of H. mitchellianum.
While engaged in ornithological investigations on the ridges which form the highest peaks of the Unicoi Mountain range in the southern Appalachians the writer located several specimens of the Fraser Fir [Abies fraseri (Pursh) Poir.]. The exact location of the thirteen trees in on and immediately adjacent to approximately two acres of open ground on the summit of Haw Knob (5472′) on the boundary between Tennessee (Tellico Wildlife Management Area) and North Carolina (Santeelah Wildlife Management Area). From the T.V.A. quadranle map of the area (Big Junction Quadrangle 140-SE) showing the state boundary it appears all of the trees are located in North Carolina by approximately 100 to 150 feet.
Dr. Jim R. Massey has assumed his duties as the new curator of the Herbarium in the University of North Carolina Department of Botany here. Massey, who recently received his Ph.D. at the University of Oklahoma, worked as an assistant at the herbarium there.
The two red pitcher-plants.-Nearly 50 years ago I observed in upland North Carolina a red-flowered Pitcher-plant differing strikingly from the lowland Sarracenlia rubra Walt.: the leaves were much larger and sparser, and the scent of the likewise larger flowers was but faint, instead of intensely rose-like. It was duly named in honor of Dr. Frank M. Jones, the foremost authority on pitcher-plant insects, Sarracenma jonesii. (1).
The frequency and percentage composition of plants was determined on levees in East St. Charles Parish (County), Louisiana. This parish is west of New Orleans and is bounded on the south by the Mississippi River and on the north by Lake Pontchartrain.
The vegetation was sampled by 55 line transects at the same locations in February-March, May-June and August-September.
Eighty-nine species were recorded in this study. Field notes indicate vernal, estival and autumnal flowering periods in the area. Eleven species were noted to flower only in the February-March study, six species only in the May-June study and eight species only in the August-September study.
Disjunct populations and fossil records indicate vast migrations of plants, and the extinction of many species over large areas of Virginia.
Four separate instances of apparent spontaneous hybridization between the native Sarracenia purpurea L. and introduced S. flava L. at Bear Lake in Lackawanna County, Pennsylvania, are described. This hybrid has been known for a long time under the name S. catesbaei Elliott.
