two or three feet. It is clear that the device is a somewhat clumsy and 
ineffective one, but the habit of the plant to grow in dense patches 
renders the chances of success fully adequate to its aeeds, as any one 
may easily realize by walking through half an acre of it as I did.

Germination of ^ardanlhus Chinensis- — Two years ago I de- 
scribed and figured what seemed to me a peculiar 
mode of germination of 7ris versicolor (Bulletin, 
Vol. ix., No. 6). The see"3s of Pardanthus Chinensis 
seem to germinate in exactly the same manner, as 
showm by the annexed figure. The seed {sd^ 
stays under the surface {sf) and sends out a long 
connective (r/), bearing the cotyledon {en) from 
which are developed the root and the leaves (Zy). 
I must assume that in this case we have to deal 
with a normal mode of germination, for I found 
numerous seedlings in the open ground, around an 
old plant that had been freely fruiting the previous 
fall, and all of them showed the same peculiarity, 
{Pardanthus Chinensis has been known for 
many years to grow abundantly near Richmond 
Hill, Long Island.)

■ Cellis OCCidentaliS, L.— A specimen of this tree 
is growing on Main St., in West Springfield, which 
is notable for its great size as also for its perfect

that it is not the " small or middle-sized tree 
scribed in Gray's Manual: circumference four feet 
from the ground, twelve feet and three inches; 
height, seventy-five feet and six inches; spread of 
branches, eighty feet. This locality seems to be a favorable one for 
the development of this tree. Though only a few specimens have 
ever been known here, they have all reached a great size. One is 
standing in Springfield nearly as large as the one whose measurements 
are given above. Two formerly stood on Main Street, which were a 
little larger than either of these now standing. They received special 
mention in Emerson's book. They were still vigorous and sound 
when cut down a few years ago. The two large ones now standing 
are apparently in all the vigor of middle life, making considerable 
growth each year. It is to be hoped that they will be spared to reach 
their greatest possible development.

^Cidium Jacobese, Gfev.— This jEcidium is a true heteroccismal 
uredine as I have recently demonstrated, and is not, as has hitherto 
been supposed, connected either with Pucciniaglomerala or P. compos- 
ttarum. On the contrary, it has its teleutospores upon Carex aremirta. 
This Puccinia is quite different from P. cartas, from which it can be
