The paper of the evening by Mrs. E. G. Britton, “A Description 
of two new Species of Ophioglossum,” is printed in this BuLLE- 
TIN, The paper also discussed the affinities, range and type char- 
acters of our eastern species of Ophioglossum, with keys and specific 
descriptions and with exhibition of tracings and numerous mounted 
specimens. 
In the discussion following, Dr. Rusby spoke of the srowk of 
Ophioglossum vulgatum among sedges on a salt marsh at Great Is- 
land, N. J. The other nearest collections reported were those of 
Austin at Closter, N. J.,and of Miss M. Sanial at Rockaway, L. I. 
Dr. Underwood sketched the characteristics of the four distinct 
types of Ophioglossum as: Ist, the section typified by O. vulgatum 
and discussed in the paper; 2d, that by O. palmatum of tropical 
America, which extends into Florida, there growing directly under 
the crown of the palmetto trees, nestled among the leaf-stubs; 
3d, that typified by O. pendulum, found in the Hawaiian Islands 
and Pacific regions, which is also pendulous from trees and pro- 
duces a spike attached almost to the middle of the leaf. In the 
4th section, with growth not over 1 inch high, the sterile and 
fertile fronds are distinct to the rooting base. 
Dr. Underwood further remarked the necessity of experience 
to find forms of Ophioglossum, especially such as O. crotalophoroides 
only one inch high, collected by him in Alabama. 
Mr. Clute spoke of the great diversity in size ee, en by O. 
vulgatum in a single locality. 
Professor Burgess referred to the occasional occurrence of O. 
vulgatum with its namesake Pogonia ophioglossoides, and to other 
companion plants with which he finds Ophioglossum associated in 
growth, as Chiogenes and especially the orchids Microstylis ophio- 
&lossoides, Habenaria hyperborea and H. dilatata: 
Dr. Underwood then exbibited. photographs of the Kew Gar- 
dens, with reminiscences of his visit of last summer. He spoke 
particularly of their formal decoration, dating back to royal use, 
and the photographs shown included one of “ Queen Mary’s Elm,” : 
planted by her about 1555, once 25 feet in girth, now ‘ponies ae 
chiefly by a series of shoots. | poe
