NEW OR NOTEWORTHY SPECIES. 307 
strict habit, narrow leaves and white flowers. It was dis- 
tributed, however, for D. incana, var. borealis. 
ViorLA BaktkRr. Caulescent, yellow-flowered, with a close 
superficial likeness to A. Nuttallii, of the same size and same 
leaf-outline, but with a subligneous branching caudex; the 
whole plant perfectly glabrous, not at all fleshy, averaging 
about an inch in length and from oval to oblong-lanceolate, 
perfectly entire, marked with about 5 almost parallel nerves ; 
petioles very slender, about twice the length of the blades; 
rather large deep yellow flowers little if at all surpassing the 
eaves. 
In moist ground, in the Bear Valley Mountains, northern 
California, M. S. Baker, June, 1896. 
PorLvaALA LONCHOPHYLLA. P. Senega, var. latifolia in 
part of authors. Notas tall as P. Senega, stem more rigid, 
fastigiately branched above, and bearing several shorter 
looser spikes of more conical outline: leaves of firmer texture 
and more veiny, their outline rhombic-lanceolate, abruptly 
and sharply acuminate, the margin finely serrulate-ciliolate ; 
flowers smaller than in P. Senega and green, the fruits 
larger. 
The above description applies to only that southern plant 
which has been confused with the northern variety and mere 
variety of P. Senega. Its seeds are not known ; and I expect 
them to furnish further diagnostic characters for a good spe- 
cies. It may also be noted that the ovate sheathing scales 
investing the lower part of the steu in P. Senega are never 
seen in P. lonchophylla. 
PotyGaLa TorReEYI, Don. Syst. i.360 (1831). This name 
must take the place of P. alba, Nutt. Gen. ii. 87 (1818), there 
being a P. alba of Buchoz (Dict. iii. 38) of as early a date as 
. the year 1770. This earliest P. alba is not in the Kew Index, 
the authors not having been able to gain access to this im- 
1 portant work of Buchoz.
