COPELAND. 
2. Ophioglossum gramineum Willd. 
Common stipe rising well above the ground; sterile lamina 10 to 15 
mm long; 1 to 2 mm broad, fertile segment arising from base of sterile, 
the spike up to 9 mm long, with 4 to 9 sporangia on a side; whole plant 
not over 4.5 cm high. 
India, New Guinea, western Africa. 
3. Ophioglossum japonicum Prantl. 
Rhizome cjdindrieal ; common stipe hardly reaching above the ground ; 
sterile lamina about -1.5 cm long, lanceolate, somewhat fleshy; fertile seg- 
ment rising from the base of the sterile, and 3 to 4 times as high, sporan- 
gia up to 50 on a side. 
Japan. 
4. Ophioglossum braunii Prantl. 
Common stipe not reaching above the ground; sterile blade lanceolate, 
typically thin but in the only reported collection from this part of the 
world said to he thicker, free veinlets few, and the midvein not branched ; 
fertile segment arising below the base of the sterile. 
Yunnan (?) ; Cape Verde Islands. 
5. Ophioglossum pedunculosum Desv. (Plate I, P>. C.) 
Rhizome cylindrical or globose, with copious fleshy roots ; common 
stipe arising 1 to 5 cm or more above the ground; sterile blade ovate, 
usually acute, subentire, narrowed abruptly to a cuneate base, com- 
monly 3 to 4 cm long, the extremes in the Philippines being 1. cm and 
7 cm; fertile segment arising from the base of the sterile or just below 
it ; stipe of fertile segment 1 to 1 times exceeding the sterile one. A 
common and exceedingly variable species, which has therefore received 
many names. I am unable to distinguish 0. timorense Miq. 
Two plants described as varieties of this species by Raciborski are raised to 
specific rank by van Alderwerelt (p. 774) : 0. inconspicuum of Java and New 
Guinea, and 0. pumilum of Java. 
Japan to India and New Zealand. 
G. Ophioglossum reticulatum L. 
Similar to 0. pedunculosum, but the sterile blade cordate above the 
short cuneate base; a less variable species here, without very small forms. 
Luzon, Mount Mariveles; in the tropics from the Carolines eastward to the 
Mascarenes. 
7. Ophioglossum obovatum Miq. Ann. Mus. Lugd.-Bat. 4 (1868) 93. 
Sterile segment 5 cm long, 12 mm broad, with a stipe one-third as long, 
oblong-obovate or more rarely broadly obovate, apex broadly rounded,
