form until more was known about the distribution of the plant and 
flowering specimens had been collected. 
On August 3-4, this year, Professor A. S Hitchcock, one of bis 
sons and myself botanized between Leonardtown and Millstone, 
St. Mary’s County, Md., and on this trip we located another area of 
the same form. We were able to refer the plants immediately to the 
Bracteolatae, although they had the appearance of T. latifolia. There 
appear to be no structural characters upon which this plant can be 
separated from T. angustifolia. The broader leaves and somewhat 
larger spikes can hardly merit more than formal or varietal distinction. 
If we should accept the views of those whom an eminent French 
authority has called “les pulverisateurs” or “les mihicists," then a 
mere difference in the aspect of a plant would compel us to erect a 
new species. This we cannot do conscientiously in the present case 
until more of the life history of the plant is known. Rafinesque de- 
scribed a number of species of Typha, but these will probably remain 
indeterminable since he gave no stable characters. 
The following summary may serve in the identification of the forms 
growing in Maryland and Virginia: 
Spikes commonly contiguous. 
"Typma LATIFOLIA L. Sp. Pl. 971, 1753. Kronfeld, Mon. (in Verh. 
Zool.-bot. Gesellsch. Wien) 176, 1889. 
Plants 1.5-2.5 m. in height: leaves flat, 10-20 mm. broad, equalling 
or exceeding the inflorescence, spikes nearly equal in length (10-30 cm. 
long); the pistillate dark-brown; pistillate flowers without bracteoles; 
pollen grains in tetrads. 
In marshes and wet places: common. 
Spikes commonly remote. 
Leaves about 6 mm. wide. 
'TyPHA ANGUSTIFOLIA L. l. c. Kronfeld, l. c. 150. 
Plants 1-1.5 m. in height: leaves plano-convex, exceeding the 
inflorescence: spikes of nearly equal length (10-30 cm. long), the 
interval varying from 1 to 5 cm.; the pistillate brown; flowers bracteo- 
late. 
In fresh and brackish marshes. 1 have observed the species in 
many localities in southern Maryland and on the Eastern Shore of 
Maryland and Virginia. Mr. McAtee has observed it at Hyattsville, 
near Washington. . 
Leaves about 10 mm. or more in width. 
Typha angustifolia var. virginica, var. nov.
