4. Botrychiwm lanceolatum, Angstrom. Specimens fleshy but 

 not showing any marked variation. 



5. Botrychium ternatum, Swz. Specimens variable, most of 

 them nearer the obliquum form than the type, and very fleshy. 



6. Botrychium Virginianum, Swz. Specimens (2 in number) 

 small, but one of them especially interesting, having two perfect 

 fronds from the same rootstock. In this instance it is clearJy ap- 

 parent from the manner in which the base of the stipe of one 

 frond sheathes the base of the other, that the bud which should not 

 have developed until another year had pushed out prematurely 

 and developed soon after the regular frond. The two individual 

 fronds had grown to very nearly the same height and dimensions. 

 The bud for the third year's growth lies snugly tucked away in the 

 vertical slit at the base of what should have been the second year's 

 frond, and a repetition of the condition described could not have 

 been expected another season as in the instances mentioned in B. 

 Lmviria, where the branched rootstock had made the permanent 

 existence of two individuals possible. 



7. Polypodium vulgare, L. A single small plant. 



8. Cryptogramme acrostichoidfs, R. Br. A large number of 

 fine specimens among which 1 find two fronds partly fertile and 

 partly sterile, the two lowermost pairs of pinnae being wholly 

 sterile in one, and with a few scattered sori in the other; the upper 

 portion of both fronds being contracted in fruit exactly as in the 

 other fertile fronds. 



9. Aspletiium Filix-foemina, Bernh. A single small frond. 



10. Phegopteris Dryopteris, Fee. Specimens characteristic, but 

 the fertile somewhat more rigid than usual. 



11. Aspidium Lonchitis, Swz. Specimens mostly small, but 

 characteristic. A single double-fronded specimen occurs caused by 

 the cohering together of the bases of two stipites. 



12. Aspidium Oreopteris, Swz. Specimens collected late, and 

 not in good condition. 



13. Aspidium spinulosum, Swz. A large number of speci- 

 mens mostly of the dilatation form. 



11. Cystopterisfragilis, Bernh. Specimens showing the usual 

 variations so characteristic of the species. A single frond forks 

 above the lowermost pair of pinnae into a two-branched top. — Geo.

The Postage Question.— Washington, D. C, July 1, 1882. 

 Editor Botanical Gazette: 



Dear Sir — The note of Mr. Trelease on "The Postage 

 on Botanical Specimens," published in your June num- 

 ber (p. 73), still leaves the question open as to what kind of 

 labels will be allowed to go with the specimens, many supposing
