lected by the Rev. D. R. Shoop of Bellevue in that State, in June |

I have just received Wolffia Columbiana in flowers from Detroit, — 
M. C. F. A., Sept. 9th. 
73. Trillium erectum, .—Mr. Bower tells me that a plant of 7 — 
erectum, L., Var. album, Pursh, which I sent him some five or six — 
years since, keeps its “creamy green” color every year. I may — 
also add that I have received a specimen of the Var. declinatum, — 
Gray, from Michigan, and I can now say, that I never saw it grow- 
ing in New York State. L hae 
74. Rubus neglectus, Peck.—I am sure that Mr. Austin is wrong : 
his suggestion about this being a hybrid. I have had this subject — 
before me ever since a boy, when I helped to collect the forms 0B 
which Babington, T. Bell Salter, and others, made so many species. — 
Iam satisfied that there is no such thing as hybridization among — 
any of our Rubi, but that all our forms result from a natural law 
evolution. Rubus would make the very best study for a vegetable 
biologist. Tuomas MEEHAN. 
7). Obituary.—Mr. Ignatz A. Pilat, the Chief Gardener of Central — 
Park, died at his residence in this city on September 17th. Mr. 
Pilat was a native of Austria, and had important positions before — 
political troubles induced him to come to this country. He was — 
connected with the Park from its inception, and held charge of 
carrying out the details of the plan. How well he performed bis 
part, that noble work bears ample wituess. Mr. Pilat published — 
in Austria, a work on Elementary Botany but, though an ardent | 
lover of the science, his occupations allowed him but little time 
to devote to it in this country. Still he was familiar with ow 
native plants, and when the ground, now occupied by the Park, 
was taken possession of, he prepared a full catalogue of the wild 
plants found there. In Mr. Pilat, botanists loose a warm symp* — 
thizer with their pursuits, and the community a most estimable - 
public officer. GC.
