32. Pellaea. ANDROMEDAEFOLiA, var. PUBESCENS. — More Speci- 

 mens of the fern called by this name in the Bulletin of January, 1881, 

 have been received, including some from Saltillo, Mexico, collected 

 by Dr. Edward Palmer. Mr. Davenport informs me that Mr. Baker 

 refers this fern to Pellaea cordata, which it resembles about as much 

 as It does P. andromedaefoUa. For the present 1 must regard its 

 position as doubtful. Dr. Palmer collected many interesting ferns 

 last year, in Northern Mexico and in Western Texas. Among them 

 are the long-lost Pellaea aspera, and the very scarce Aneimia Mcxi- 

 cana. He found Notholaena Grayi with both white and yellowish 

 powder, and N. smuata in a great variety of forms. I hope to have 

 a full account of his ferns ready before very long. 



33. AsPLENiUM PiXNATiFiDUM, Nutt.— Writing of this little fern 

 at page 63 of Ferns of N. America, Vol. I., I said : " I find one or 

 two instances of a slight enlargement of the apex, as if there were 

 an attempt to form a proliferous bud." I have now received a plant 

 in which one of the fronds has produced a terminal bud, which has 

 developed five little fronds. The plant came with the following 

 letter trom a venerable botanist to whom all fern lovers have Ion 

 been under obligations.

My dear Sir 



Moulton, Ala., Jnne 28, 1881. 



I picked up on the 21st of [une, the fern which you will find 

 enclosed, Asplemum plnuatifidum, Nutt., which exhibits as clear an 

 instance of growing from the tip of the frond as Asplenium rhizo- 

 p/iyUum (or Camptosorus rJiizophyllus), I have- seen one specimen of 

 hke character before ; and Mr. John F. Beaumont, now dead, advised 

 me that he had found a like plant in South Alabama. 



Very truly your friend, 



Thomas M. Peters. 



34. BoTRvcHiUM MATRiCARiAEEOLiUM,.Al.Braun.— Mr.and Mrs. 

 Morgan found good specimens of this rare fern near Columbus, 



.}^a'^^^^1 '>^\' Professor Joseph Milliken was also associ- 

 a ed with them in the discovery. This is the first record of this 

 plant growmg west of the Alleghanies and south of Lake Superior.

94.. Vernation in Botrychia.-I have had placed in my hands 

 Kaminatlon two Botry^iums whose buds have thrown a doubt, 

 tor the first time in my experience, on the reliability of the bud-form 

 as a test for the determination of the smaller species of the genus. 



One of these specimens is a large, finely-developed, unquestiona- 

 ble specimen of B. sunplex of the compositum form, and ;ear?y terna"e ; 

 the other is a specimen of B. matricariaefolinvl of good size and 

 with the sterile division cleft nearly into t/o portions^ 



The specimens were collected' in the Lower Merrimac Vallev 

 Essex Co. Mass., by Mr. W. P. Conant, who is thus entWed to the
