it was the same with Helonias bullata. Walter's Melanthium 

 dioicum, I take to be a good synonym of our Veratrum luteum. 



The Acnida cannabina, in your marsh, pleased me a great deal, 

 as I had never seen it before, and had looked anxiously for it. 



Of all the dried specimens you sent, I have not seen any before, 

 and as I only have the one specimen, I forbear to examine them 

 closer, until I see them alive. 



We have 2 G ac alias ; but none is, by the smell, suaveolens. The 

 one has very glaucous leaves ; the other grows along the shores 

 of the Pequea, and is more white. The first I take to be atripli- 

 cifolia. 



The Mespilus and Crataegus should certainly be joined. Of the 

 latter, I can't make out what is species, and variety. I think 5 

 species are really different, near Lancaster. 



Vaccinium is likewise one of my Adversaria. I will give you 

 the short description, to see how we can find the Liniuean names : 



1. Floribus racemosis bracteatis, foliis ellipticis subtus tomentosis, 



bacca purpurascente, caudice arboreo. This is the largest 

 sort, sometimes ten feet high ; flowers May 1 ; grows in 

 swamps; and I take it to be corymbosum . 



2. Raeemis bracteatis, pedicellis bracteolatis, corollis eampanulatis, 



foliis ellipticis subtus pallidis, bacca ccerulea. This is our Blue- 

 berry; and I take it to be frondosum \_G-aylussacia, 

 H. B. K.]. 



3. Raeemis bracteatis, pedicellis bracteolatis, corollis ovatis, foliis 



lanceolato-ovatis viscosis, bacca nigra. This is the common 

 black Whortleberry ; and I take it for Alton's resinosum, or 

 Clayton 61. 



4. Pedunculis solitariis unifloris bracteatis, antlieris corolla longi- 



oribus, foliis oblong is integerrimis, bacca globosa alba. This 

 is not eatable ; and I take it to be, with some doubt, stami- 

 neum. It has many varieties. Clayton describes one much 

 like it, which is classed under frondosum. 



5. Pedunculis solitariis unifloris bracteatis, foliis ellipticis et obo- 



vatis integris, bacca globosa atra. This I never found in 

 blossom. It is a low shrub. 



The native Salices, likewise, prove very hard for me. I count 

 seven or eight different species ; but am not able to class them. 

 However, as I have marked every sort, I hope by another year's
