LOCAL ALBINO PLANTS. 265 
QUADRULA PARKERI, GEISER, A SYNONYM. 
In my last published study* of the synonmy of Tritogonia 
tuberculata, I inadvertently overlooked Ortmann’s nom. nov. 
Quadrula Tritogonia, 1909 (Nautilus XXII.: 101; An. Carn. 
Mus. V.; 193), which has nearly three years’ priority over my 
name. Upon the premise, then, that the pronounced sexual 
dimorphism of Tritogonia does not entitle it to generic rank, and 
that on the basis of its gravid characters it is properly a Quadrula. 
Ouadrula Tritogonia Ortmann, 1909 is the only name that can be 
applied in accord with the provisions of the International Code 
and all the common-sense vrtinciples of nomenclature.

SOME LOCAL ALBINO PLANTS. 
By J. A. NIEUWLAND. 
While botanizing near Mineral Springs, Porter Co., Ind., 
May 30, 1912, I found several specimens of albino Hairy Phlox, 
(Phlox pilosa Linn.). Such plants are not unusual, but may be 
worthy of note. They were found along a road leading to the 
dunes of Lake Michigan in black marsh soil, together with numbers 
of normal plants. The flowers were perfectly white without the 
least trace of color in the corrolla, nor the usual darker tinge of 
purple on the parts of the inflorescence or stems. The perfectly 
green color of the stem wasso notable that one of the unblooming 
plants was taken and, when transplanted proved to be a pure 
white-flowered specimen in bloom. I have frequently, and es- 
pecially in the dune region met with pale-flowered plants in sandy 
sun-exposed places, but none were entirely snow white. In every 
other respect the albino resembled the purple flowered normal 
plants. A pressed specimen was secured for the University Her- 
barium (No. 10093) and several plants were brought home and 
planted in the University grounds. All but one died, possibly
