or sometimes gemmiform and radical, and at times axillary 
(W. 3-57)0 
Through innovation, the fertile stems of F. Nicholsonii often bear 
from two to four short branches, each of which terminates in a female 
flower, so that stems bearing a cluster of two to four capsules are 
found. 
F. flavicans , Sch. ms. in Herb. Kew (Guadeloupe (L’Herminier)), 
is F. radicans, Mont. (Ann* Sci. Nat., S6r. 2, xiv, p. 345). Montague 
(loc. cit.) and Mitten (Muse. Austr. Amer., p. 581) describe the fruit 
as terminal. It is, however, both terminal and truly lateral (clado- 
carpous). In the latter case a very short special branch is terminated 
by the perichaetium, just beneath which innovations often occur, in 
the same manner as when the perichaetium is terminal on the main 
stem. The species is autoicous, and the position of the male flower 
is variable. It may occur in the axils of the stem-leaves, just below 
the female flower, or it may terminate a short lateral branch, similar 
to that of the lateral female flowers ; it sometimes occurs, at the base, 
on the lateral female branches. F. radicans has been recorded 
hitherto only from French Guiana and Brazil. Schimpers specimens 
have a slightly different facies from those from the above places, due 
to the plants being old, and the innovations consequently very 
numerous. 
F. involvens , Sch. ms. in Herb. Kew (N. Hollandia), agrees well 
with small crisped forms of F. glaucescens, Hornsch. (Linnaea, 1841, 
p. 154), from Africa. 
F. circinnans , Sch. ms. in Herb. Kew (non F. circinans (Sch.), 
C. Mull., Bot. Zeit., 1864, p. 340), from Java, is F. Zippelianus , Dzy. 
e. Mlkb., Bryol. Javan., 1, p. 2, t. 2. 
F. macrostachys , Hpe. ined. (ad rup. hum. Austral., leg. Dr. F. 
Muller), in Schimper’s Herbarium is F. rigidulus , Hook. f. and Wils. 
F. angustifolius , Sch. ms. in Herb. Kew (non Sulliv., Proceed. 
Am. Acad., p. 275, 1861) (abundant on moist rocks in ravines on 
the Pouce, Mauritius (Ayres, July, 1862)), is F. ovatus, Brid., 
var. planifolius , Besch., hitherto recorded only from the island of 
Nossi B 6 . 
F. stolonifer, Rehm. Muse, austr.-afric. 1875-77, Nos. 294, 585; 
Kindb. Enum. (nomen nudum) ; from Cape Town is F. bifrons (Sch.), 
C. Mull., Bot. Zeit., 1859, p. 198.
