          My Scirpus obtusus I enclosed you in a letter
 with my opinion that it is a variety of Sc cospitorus [Scirpus cespitosus].
 Enclosed with the packet you will find a small
 bottle containing fresh species of Poa maritina,
 Poa geniculata, ([?]), Arenaria peploides, Potentilla
 amerina, Arethusa bulbosa.

 I should like your opinion of all the specimens
 to which I have affixed numbers, except where
 the specimens are bad, in which case I will not
 tax you.

 I have 3 species of Rubus which to me are
 new & to which I request your attention. The first
 I sent you by Dr. Rogers, the 2 last are in the 
 packet.

 R. setosus [Rubus setosus] caule erecto-vichineto, setoso-aculeolata
 foliis ternctis quinctisve, utrinque glabris, cobycibus
 tomentosis.

 In a swamp at Sudbury 20 miles from
 Boston. Fruit red, ripens very late. Prickles soft, bristle like.

 R. sempervivens [Rubus sempervirens] Caule prostrate, aculeolata;
 foliis ternctis nitisis, sempervirentibus; racemes parcifloris

 In swamps, fruit black, sour small. Pursh seems
 to have compared it with his obovatis which is
 hispid & subherbaceous. This is prickly, woody &
 evergreen.

 R. frondosus [Rubus frondosus] resembles R. villosus [Rubus villosus] but differs
