PLANTS FROM VARIOUS PLACES 179 
just outside of Michigan City, Ind., as also at Grand Beach, 
Mich. with another variety to be described hereafter. 
These differences point to the fact that our dune plant is as 
different from the type as any of the Southern plants, and even 
at that, the name mollis is preoccupied, should it ever merit specific 
standing and therefore I propose to name it 
Ptelea trifoliata var. Deamiana Nwd. var. nov. 
Haud arbor sed frutex cum foliis P. trifoliatae sed minoribus 
et facie inferiore sparsim tomentulosis maturis, immaturis quidem 
dense tomentulosis tomento deciduo; foliola abrupte acuta tenui- 
uscula; fructus idem ut in P. trifoliata; flores decandri suaveolentes. 
Hardly a small tree, but usually a medium sized shrub with 
the foliage of P. trifoliata but leaves smaller as a rule, somewhat 
sparingly tomentulose when old, and white silky appressed tomen- 
tulose when young; twigs and young petioles densely tomentulose 
with a minute spreading deciduous tomentum: leaflets abruptly 
acute, thin except in straggling sterile sand plants with creeping 
prostrate branches sending up short erect ones with paler bark 
and even smaller leaves: fruit as in the type: flowers having the 
delicate pleasant odor of Dianthus plumarvus. 
I have named the plant in honor of Mr. Chas. C. Deam who 
first reported it from Indiana, or at least a specimen that may 
be referred here rather than to P. trifoliata. The plants which I 
select as types are moretomentulose than Mr. Deam’s plant which 
he kindly sent me for examination. The leaves too are smaller. 
I refer here for the present at least, specimens with remarkably 
small leaves and paler densely tomentulose leaves. The plants are 
sterile, creeping by silvery shining, prostrate stems and sending 
up small branches from these. They grow in the last dunes border- 
ing on Lake Michagan. They venture almost as near to the shore 
as Chamaesyce polygonifolia, (Euphorbia polygonifolia Linn) 1 
collected such some miles south of St. Joseph, Mich., also at Mich- 
igan City, in 1908, no. 216. of my herbarium. As type I may desig- 
nate No. 4087 collected at St. Joseph, Mich., along the Pére Mar- 
quette Railroad some distance from the lake. Another specimen 
No. 1500 collected in 1906, is equally typical; also No. 888a, 
gathered at Michigan City, June 19, 1911; as well as No. 924 
from Grand Beach, Mich. and No. 888 found growing in close 
proximity to P. trifoliata. I have in many places observed the
