806 PITIONIA. 
definite minute denticulation, freely feather-veined and faintly 
reticulate, the veins and veinlets with here and there a trace of 
seaberulous roughness, but mostly quite smooth: peduncles 
rather slender, but hardly equalling the leaves: corollas at their 
best more than two inches wide: filaments rather narrow : pods 
3 inches long, slenderly beaked under the large stigmas. 
Local on a volcanic cliff on Santa Catalina Island, March, 
1896, Mrs. Trask ; type specimens in my own herbarium. The 
leaves here are firmer, though not as thick as in D. flexilis, a 
species which also seems to inhabit Catalina. 
SUGGESTIONS REGARDING SANGUINARIA. 
In but two localities—but these rather remote from one an- 
other—have I had opportunities for gaining any familiarity 
with this beautiful and interesting genus. Many years ago, in 
southern Wisconsin, | knew well its haunts, and sought it out 
every spring at its flowering. After that, for more than twenty 
years, my herborizations were always beyond its range. 
In 1896, in woods of the District of Columbia, I was de- 
lighted with the copiousness of Sanguinaria as it came into 
flower in the latter part of March; and I was at first strongly 
impressed by the fact that these were not such bloodroot flowers 
as I had been used to see in Wisconsin ; and the difference was 
one easy enough to name. ‘The corolla here was quadrate, and 
of very numerous petals. That of the Western woods I knew 
had been circular in outline, and made up of not much more 
than half as many petals. 
And now, after ten seasons of observation on the plant as it 
occurs plentifully about Washington, I have looked into the 
herbaria to see what proof I might tind there of notable differ- 
ences in Sanguinaria as it comes in from different sections of the 
country ; and I seem to find, as usual, more there than I had 
expected.: Then, going from the herbarium to the old standards 
of early American botany, I have been greatly surprised to find
