Polypodium lagunense Christ. 
Epiphytic on exposed ridges 1,400 to 1,800 in. alt. (Xo. 59S4, 5085). 
This spocies is already known from Mount ^laquiling, Luzon, and from Mount 
Silay, Negros {Whitford 1535). As a matter of affinity it unquestionably 
belongs in the Crypsinus group, the usual elas.sification of "Phymatodes" accord- 
ing to the composition of the frond being in this case as unnatural as possible. 
The pinniie of Polypodium lagunense resemble the whole simple frond of /'. num- 
muhriuiHj the distinction of sterile and fertile parts being the same in both 
species. The simply pinnate frond furm of P. lagunense is not yet quite stable, 
for Merrill found two plants (No. 5984) with large bipinnate fronds. 
Polypodium accedens I$l. 
Epiphytic in liuiiiid thickets at 150 m, alt. (No. 5002), typical form; and 
on rocks along the Alag River at 350 m. alt. (No. 5993). 
Malaya and Polynesia. 
The plants collected at an altitude of 350 m. are rather larger than is 
usual in this species. Some fronds are typical in form and fertile only at the 
constricted apex; others are narrower and fertile almost throughout, wliile 
entirely sterile ones are notably broad. This variation is in the direction of 
P. nuinniularxum and P. Whitfordij indicating the probability that both have 
descended from P. accedens in this locality. 
Polypodium punctatum (L.) Sw. 
On rocks along the Alag River at 350 m. alt. (No. 5091) ; dried fronds reddish 
in color. 
Africa to Polynesia.

Common in Mindanao.
