R. David Whetstone tells me there are errors in his article, “New or Noteworthy Records for the Flora of Alabama,” Castanea 44:1. 1-8. 1979. Anyone interested should write him for these corrections.

This work is a seventh volume in the ongoing Illinois Flora. It is done in the previous style, of good descriptions, keys, drawings, and county range maps (Illinois only). Excellent for anyone needing a knowledge of the plants (restricted sense) of Illinois.
A technical bulletin from the U.S.D.A. Agricultural Research Service, which exhaustively studies the alfalfa complex, reducing it to 9 facies (possibly subspecies), on the basis of legume characters and flower colors.
A rather short but well-written book on the general vegetational aspects of the world. The book is divided into two parts, environmental and ecological principles, and the pattern of world vegetation.
This is a guide for stripmine operators and others dealing with coal spoil revegetation. The author covers trees, shrubs, vines, brambles, grasses, legumes, and several forbs. A short description of performance, pH and fertilizer requirements, and other information is given for each species. Concise recommendations on the uses of species are made.
The 19th Annual Edition of the Educator’s Guide to Free Science Materials gives a subject/title/source listing of some 1,658 items available to the teacher. While admittedly primarily for the high school level, there are many items of great interest to both lower and higher levels. There are over 1,000 films (mostly 16 mm sound) which cover many science subjects, but there are many other free materials of potential value.
The Flora North America project (FNA) was recently revitalized by the Man and Biosphere Program (MAB) as a binational effort between the United States and Canada, to produce a conventional flora of the vascular plants of North America north of Mexico using traditional methods.
Keys, distribution maps, habitats, references, and nomenclature are given for the Onagraceae that have been found in Georgia, native or naturalized. Genera included are: Ludwigia, Oenothera, Epilobium, Circaea, and Gaura.
Buckleya seeds germinated after cold storage at 3℃ for 4 months. A host is not necessary for germination, and seedlings will develop without attachment to a host. Seedlings grown without hosts developed the same as those with hosts. No differences in parasite vigor were observed in 5-month-old seedlings when grown with 19 different tree species from two gymnosperms and nine angiosperm families. All species except Liriodendron tulipifera were parasitized.
A study of vegetation of Fisherman Island, Virginia, was undertaken to correlate present vegetative communities with past geomorphic events. One hundred and thirty-nine (139) plant species, and 14 plant communities, were identified and described. These included 8 county records and 2 state records for Virginia.
