          deterred me from attacking the numerous material in my
 hands. I shall be much obliged to you for your monograph
 so kindly offered; and it shall be an incentive to
 study the Cyperaceae next season.


 Your offer of specimens and books to study
 one or the other family is very kind, and I shall
 apply to you, whenever I should be in want of them.
 Meanwhile receive my heartfelt thanks


 very truly


 yours

 Of Physalis I believe we have 4 [added: or at least 3] distinct species, but a good many varieties;
 2 are annual, and 2 perennial; the 2 annual are very distinct; but the
 2 perennial might possibly be varieties; all the Southwestern species
 known to me, I consider as varieties, possibly of P. viscosa. Styles, Stamina,
 Shape and Venation of fruiting calyx appear to [affirm?] the [best?] characteristics.
 Has the 9th vol [volume] of De Candolle Prodromus ["Prodromus systematis naturalis regni vegetabilis....," vol. 9, 1845] not yet arrived?
