478 MR. W. B. HEMSLEY ON CHINESE PLANTS. 
Quercus Forvrana, Hemsl. (Hook. Ie. Pl. t. 2664, ined.), is a 
distinct new species, allied to Q. cornea, Lour., from which it 
differs in having very pubescent leaves with much more 
numerous lateral nerves. It belongs to a small group charac- 
terized by a thick bony shell to the nut, and lobed cotyledons, 
caused by false septa intruded from the endocarp, much as in 
the walnut but by no means so regular. 
AncHANGIOPTERIS HENRYI, Christ d Giesenhagen (Flora, 
1899, p. 72, cum figura).—This is one of the most interesting of 
recent discoveries of new ferns, forming, as it does, a connecting 
link between Angiopteris and Danea. It differs from Angi- 
opteris in the absence of “ nervuli recurrentes," which are not 
true nerves, but plates of colourless cells, extending from the 
margin towards the midrib. The authors give the differences in 
the following words :—“ Differt ab Angiopteride soro lineari 
nec ovali, mediali nee subterminali, indusio majore, sporangiis 
multo numerosioribus, fronde multo minore, simpliciter. nec 
pluries pinnata, et nervulis recurrentibus nullis." “Differt a 
Danga stipite rachique exarticulatis, sporangiis haud in synangia 
coneretis." 
Recent diseoveries in China have increased the number of 
ferns to about 300 species, including upwards of fifty new 
ones.
