          I am only pleased particularly with
 the Gramineae & Cyperaceae I have
 large collections of such as are found
 here & in the State of N.Y. I would
 like to exchange them for such as
 I have not either American or European Species - of Rhynchospora
 I have many sets of the following
 species with printed labels. - viz.
 Rhynchospora cymosa, Nutt.
 R. Torreyana, Gray.
 R. fusca, Roem & Schultz
 R. gracilenta, Gray.
 R. alba, Vahl.
 R. [Thuishernii?], Carey
 R. glomerata, Vahl.
 R. cephalantha, Torr. and
 Ceratoschoenus macrostachys If you
 could in any way procure me any
 species not in this list, either single
 or in quantities I should be glad?


 Inclosed I send you a fragment
 of a plant I find sparingly along the
 sea coast in the sand, what is it?


 By the next spring I hope to be ready
 to make large exchanges particularly
 in the Graminaceae & Cyperaceae. If
 you hear of any botanists who desire
 them please direct them to me.


 Very cordially yours


 P.D.Knieskern
