GENERA OF FERNS. 659 
Has. Mountains of Pundua, a lofty range on the eastern 
parts of Bengal, not far from the district of Silhet. Francis de 
Silva. 
My own specimens of this remarkable and very distinct 
plant, exhibit only the male amenta. The fruit is copied 
from Dr. Wallich's figure. I do not find the leaves by 
any means constantly opposite, nor, consequently, the pe- 
duncles. It is placed in Mr. Bennett's 4th section of the 
genus “Dammaroidee,’ which he thus distinguishes :—Flores 
monoicd. menfa mascula fasciculata; fasciculi pedunculis 
(ramulisve brevibus) oppositis, axillaribus, nudis suffulti: 
Flores feminei oppositi, similiter pedunculati ; receptaculo 
aucto carnoso ex axi spice abbreviate 1-florze, cum squamulis 
pluribus apicibus tantum liberis coalita; squamula terminali 
bracteole subtendentis vicem gerenti.— Folia opposita, ovata, 
nervo medio destituta stomata in utraque pagina gerentia. 
Tas. XXIII. Male branch of Podocarpus latifolia, nat. 
size. f.1. Anther magnified; f. 2 (from Wallich) fruit, nat.

Tribe VII. Crarnea, J. Sm. 
Sori round, globose, intra-marginal, medial or axillary, 
generally furnished with a calyciform, or lateral interior 
attached special indusium; or naked, or furnished with 
articulate hairs that involve the sporangia. Receptacle elevated, 
globose, or columnar. Sporangia usually sessileand compressed. 
bs. The number of species, described by authors as 
belonging to this tribe, does not exceed 80, and I am inclined 
to consider that much above the real number ; their determi- 
nation being difficult, on account of the specimens in her- 
aria consisting, usually, only of small portions of fronds,
