 Vol. VI. March 1903. p. 38.) 



Calls attention to the distinction between the above species and P. 

 arcticum. The former having much longer, less curved capsules, less 

 imbrieate leaves etc. The basal leaf cells of the two species are quite 

 variable. 



The exothecal cells in P. articum on the incurved side are short, 

 while on the opposite side they are rectangular mostly 2 to 3 times 

 longer than wide. In P. Tschuctschicum the cells are more uniform 

 around the capsule. Moore.

 living specimens of the European and American royal fern, the 

 treatment of Willdenow is confirmed and the above name recognized 

 as correct for the American fern. Trichomanes Petersii : notes as an 

 additional Station, Saratogo, Mississippi. Phymatodes exigumn

 P. Swartzii. Hypolepis repens. Evidence of this species being indigenous 

 to the United States; found atOakland, Florida. Pteris latiusculo.

ecallosa, Sprague. (The Gardeners' Chronicle. Vol. XXXIII. 



3 rd ser. 1903. No. 853. p. 274.) 



This species is similar to Swainsona coronillaefolia, Salisb., but is 

 distinguished by the absence of plate-like calli on the vexillum and by 

 the presence of a terminal tuft of hairs on the style's upper side and 

 further by the silkiness of the ovary. F. E. Fritsch.
