“All the plants I send you are young ones: the question is, did 
they grow from this year’s seed? ‘You will, on examination, find 
tiny red points in the bark of this year’s wood, and observe that 
the largest plants are in the older wood, and that none of them are 
the plants of last summer’s growth.” 
76, Note from Dr. Gray—Mr. Peck of Albany sent me, early last 
autumn, a good specimen of a parasite on Abies nigra, asking what 
it was. I replied that it was the female of an Arceuthobium, most 
likely A. campylopodum of Engelmann—to, whom I advised he 
should send specimens ; that the discovery was an interesting and 
unexpected one. As Dr. Engelmann seems to have been supplied 
with much smaller and less developed specimens than I was, I ven- 
ture to suspect that he will yet conclude that it is his A. campylo- 
vodum. 
The curious thing about the discovery is : 1st, that it should not 
have been detected before ; 2nd, that if should, after all this over- 
looking, be found during the same season by two persons, in three 
different counties, and so abundant as to disfigure or even to des- 
troy the trees it infests. 
I did not answer your communication at once, because I knew 
that the plant had already been brought to the knowledge of the 
Torrey Club, and because I sent it at once, with the specimen, to 
Dr. Engelmann, who has only now returned it.

77, Sesuvium.—Myr. Merriam informs us that Dr. Gray has written 
him as follows : “No doubt your Sesuvium is S. pentandrum, and 
that that is a good species. I have no specimens of 8. Portulaca- 
strum from the Northern States. Equally Ihave now no doubt — 
but that S. sessile, Nutt. (not DC.), is this S. pentandrum, as you 4 
say in the Bulletin.” — a
