1909] Collins,— On the Flora of lower Cape Cod 131 
mum as well as the old S. officinale var. leiocarpum. Euphorbia 
Cyparissias had. spread from old gardens, and in many cases had 
bracts of a very deep orange, brighter than I remember seeing elsewhere. 
The family Cistaceae seemed to find conditions fairly comfortable, 
as Helianthemum canadense and H. majus, Hudsonia tomentosa and 
Н. ericoides, and Lechea maritima were all abundant. Of the Irida- 
ceae, Iris versicolor was not uncommon; Sisyrhinchium angustifolium 
and S. atlanticum seemed about equally frequent. Of Liliaceae 
I saw only Lilium philadelphicum (in 1906 only; 1907 and 1908 
were dry seasons and it did not appear), Smilacina stellata, Smilax 
rotundifolia and Asparagus officinalis, the last escaped from cultivation 
and common. In nearly every family curious absences could be 
noted, which it would take too long to detail. I secured only six 
species of Carex, three of Cyperus and six of Juncus; evidently the 
locality is better suited to Juncus than to the others. Violets were 
not common, but in one place I found Viola fimbriatula growing and 
fruiting freely in pure quartz sand, no other plant in its vicinity but 
Ammophila. The common Oxalis was O. stricta, with large flowers 
of a deeper yellow than in O. corniculata, our usual species near Boston. 
The most showy flower was Hibiscus Moscheutos, whose large, Holly- 
hock-like flowers seemed strangely out of place in their impoverished 
surroundings. 
It remains to mention a few species, whose occurrence here is of 
definite interest. Along the roadsides all through the town, was a 
plant with dense tufts of gray-green linear leaves, which in early sum- 
mer bloomed and proved to be the old-fashioned garden pink, Dianthus 
plumarius. It does not appear in the Manual, but is evidently quite at 
home here. Trifolium dubium, not a common plant generally, was 
not infrequent. The only Amelanchi r was the rather unusual А. 
oblongifolia var. micropetala; Plantago aristata var. Минат, a form 
not mentioned in the Manual, was not uncommon in dry fields. In 
Кнорока, Vol. ХІ, p. 58, will be found mention of a small Aster 
which I found here, which has proved to be of interest in settling : 
doubtful point as to A. surculosus; and the occurrence here of Agropy- 
ron pungens considerably extends its range, and probably establishes 
its title, which has been disputed, to native American citizenship. 
The finding of Lactuca Morssii also extends a range, in this case of a 
“Ruopora species." In closing this list of species, I must add the 
consecrated formula. “Through the kindness of Prof. Fernald of the
