out runners two or three inches under the surface, and to a distance 
of 12 to 20 inches, where a young plant springs up. For this piece _ 
of generosity on its part, I have planted it alone, away from. other 
ferns, where its ropy runners may be removed without danger of 
disturbing other things. eee 
Other plants that produce seedlings with me are Jeffersonia di- 
phylla, Pers., some Trilliums, and I see young plants of Agave Vir- 
ginica, L. Asclepias verticillata, L., is almost a weed, coming up 
through the tan iu the walks. I should say that the different beds 
that contain the above-named plants are not common garden soil, 
but made with much trouble from leaf mould and soil broughtfrom _ 
the woods. . 
There is much difference in plants in adapting themselves to eir- 
cumstances. Frangula Caroliniana, Gray, grows well in common — 
soil, while Epigaa repens, L., will not be suited anywhere. I cannot 
keep Cypripedium acaule, Ait., although I have seen it in nearly pure — ; 
dry sand and in wet sphagnum. It is curious that C. acawe has — 
only one bud to each plant. Itis the only one with a divided lip, — 
and of our species the only one without a leafy stem. WwW. B 
Il, Rhus Toxicodendron, L.—While riding in Chester Co,, Penn., near : 
the Delaware State Line, I saw a cow on the bank of the road, three — 
or four feet higher than the roadway, nibbling this plant which grew _ 
in the hedge. On my return I enquired of a farmer if cows were 
known to eat the poison vine. He said he had known such cases, — 
but whether it had any effect upon the milk he did not know. 
Some years ago I wished to get Rhus toxicodendron. I was i- 
formed that the difference between that and R. radicans was, that 
the latter had entire leaves, while the leaves of the other weré 
notched. Ihave found R. radicans at Bloomingdale having entire — 
and notched leaves on the same branch. Subsequently I supposed 
that aerial rootlets might be a distinction, but I found on the rocks 
at Bergen Heights R. radicans growing up the face of the rocks, the — 
main stem well fastened. to the rock by the rootlets, and at the 
height of six or eight feet from the ground giving off a horizontal 
branch of several feet in length, and perfectly free from rootlets. | 
I have seldom found the climbing kind on trees of any height 2 
swamps ; there it is more likely to be bushy, or growing on stumps __ 
12, Finaneial—Our expenses for the first two volumes exceed our 
receipts $53.33. There are about $26 due which will probably be 
paid. As our small mail, if unpaid, must be delivered at the Genera 
Office in the city, we havenot always leisure to forward it. Those 
‘who wish it can insure a more prompt despatch by inclosing to U8 
twenty cents for the remainder of the year. The last number was 
vexatiously delaved by difficulties in the mailing.

distribution of these Orders.
