EMBRYOPHYTA ASIPHONO- 
GAMA 
CRYPTOGAMIA 
Plants not bearing true flowers—that is, having no stamens nor ovules and 
never producing seeds containing an embryo. 
Pteridophyta 
FILICES (Ferns) 
Sporangia minute, placed on the margin or under-surface of the leaf or frond, 
rarely somewhat larger and arranged in spikes or panicles. Spores all of one 
kind. 
CYATHEACEAE 
The Cyatheaceae are mainly tropical, and are distributed over the old and 
new world more or less evenly. The family is restricted to localities with a very 
moist and uniform climate. They are found rarely in areas with a precipitation 
of less than 100 em. annually. Against temperature they are more or less inde- 
pendent, as they still thrive prolifically in regions where mild frosts occur, as, 
for example, in Tasmania. With the appearance of this family in the Stewart 
Island of New Zealand, it has reached the border land of the Polar region. 
CIBOTIUM Kaull. 
Pinonia Gaud., Dicksoniae sp. autt., Hk., Bk. 
Sori globose at the apex of a vein, marginal, enclosed in a prominent coriaceous, 
deeply 2-valved involue ere, the outer box-shaped valve eg from the margin of ‘the 
segment, but being of different texture. Spora ngia stipit Annulus with a stomium 
consisting of thin kee cells, which ¢ can easily be bare from those of the walls 
f the sporangium e ferns with v ay large leaves, which are usually tripinnate, the 
last pinnae with es shlong segment 
The distribution of the six or eight existing species, which seem to be very 
closely related, is very remarkable. C. guatemalense and C. Wendlandi occur 
in Guatemala, as well as C. Schiedei in South Mexico and Guatemala, in culti- 
vation for a long time. C. Barometz occurs in the monsoon districts of East 
Asia; another subspecies (C. Cumingi) is endemic in the Philippine Islands, 
while three are peculiar to the Hawaiian Islands.
