these matters. The balance of probal^Ht}', howe\er, indicates 

 that we are deaUng with a teratological case in\()l\ing an other- 

 wise pure strain of the Red Oak. 



To dispose of this tree in nomenclature is not without diffi- 

 culty. It manifestly does not deserve rank as species, subspecies, 

 variety or form in the orthodox taxonomic sense. Its presenta- 

 tion as an horticultural variety seems to be not wholly objec- 

 tionable. The specimen belongs to a species well known in 

 cultivation, grows in a public park, and is a precise match of 

 such accepted varieties as Qnerciis robiir var. heterophylla and 

 Acer platanoides var. laciyiiatiim . It may be said that the use of 

 horticultural variety is unbecoming whenever the specimen on 

 which the variety is established is not in cultivation. The ob- 

 jection has some merit, but it assumes for certain that our Oak 

 will not be cultivated and reproduced. This much, of course, 

 does not belong to the record as proved. The writer, therefore, 

 announces: Quercus borealis Michx var. (hort.) nov. flabellata 

 — Lamina plerTimque basi abrupte irregulariter constricta den- 

 tata, figura quoadmodum flabellata (Blade usually abruptly 

 and irregularly constricted dentate at the base, in outline more 

 or less flabellate). — Type in the Herbarium of the N. Y. Bo- 

 tanical Garden, leg. Leon Croizat, August 31, 1936. Sizes: Leaf 

 up to 9 inches long, the petiole about 1\ of an inch, the entire 

 median part of the blade not over 2-2 1 inches broad, with lobes 

 up to 2| inches long, 2 inches broad. Acorn to 1 inch long, f of 

 an inch broad, inclosed about \ by the cupule; cupule up to 

 I of an inch deep. 



Baenitz presented (Allg. Bot. Zeitschr. 9: 85 e/ seq., 1903) 

 Quercus Richteri for Q. borealis var. maximaXQ. pahistris. The 

 discussion that justifies the presentation of the binomial is con- 

 vincing so far as the cited text reads, and Q. Richteri has found 

 place in standard works, in some of which it is briefly described. 

 The writer, thanks to the kindness of Dr. E. J. Palmer, has 

 seen the specimens of Q. Richteri preserv^ed in the herbarium of 

 the Arnold Arboretum. On the strength of an isotype (Dr. C. 

 Baenitz, Herbarium Dendrologicum No. — , Flora Silesiaca, 

 1/10-12/10 1902; without fruit) Q. Richteri is justifiably re- 

 duced to a synonym of Q. coccinea Moench. Three specimens
