The same plant witli simple leaves but with their bascs out into irrefirular 

 pinnate seoments has been called by Bory, Scolopendrium Durvillei (Kunze 

 Schkuhr Suppl. Tab. 5.).

The specimens agree well with the description of the species. The secondary 

 leaves, wliich I presume belong with the specimens cited, but without being able 

 to determine tliis point witli certainty, differ from thosc of tlie prcceding species 

 in their linear, more elongated segments and with a tendency of the frond to 

 become gradually larger and to present auricles at the anterior base of the 

 pinnules, a point of union with Asplenium of the cuneatum group, conf. Verhandl. 

 Schweiz. Nat. Forsch. Gcscll. (1906) Tab. 6. The secondary leaves mentioned 

 above are those of specimens from Mindanao (Wurbury) , Luzon (Warburg) and 

 Nortli Celebes, Bojong (15321 Warbury) .

LuzoN, Province of Rizal, Montalban (Lohcr) January, 1906, a vcry similar 

 form, but slightly larger from the Laniao River, Province of Bataan (85 Barncs) . 



This species is distinguished by its very unequal and crenulate pinnae, one 

 specimen with secondary leaves bearing also some adult leaves, which, although 

 small, are strongly crenulate. The secondary leaves arc rather large, 10 cm. 

 long, 4 cm. wide, nearly sessile, tripinnatifid, the rachis reddish, flexuous, the 

 pinna; ovate, obtuse, 2 cm. long, 1 cm. wide; the pinnules serrate, cut into linear 

 segments which are obtuse, often bi- or tri-furcate, 2 mni. long, 0.5 to 1 mm. 

 wide, the color very dark green.

MiNDANAO, District of Zaniboanga, San Ramon ( 1749 Copeland) , alt. 750 m. 

 Judging from the above authentic specimen tliis is a very distinct species, 

 characterized by the cartilaginous borders of tlic adiilt pinnae.

The typical form, identical witli specimens in my herbarium from Java, Ceylon, 

 Himalaya and Samoa. 



49. Stenochlaena sp. 



This is tlie phint described by ine in BuU. Hcrb. Boiss. II. 6 (1906) 997. and 

 wliich approaches »S'. Milnei Underw. ex descr., but wliich it is impossible for me 

 to identify specifically because fertile fronds are lacking.

This species, found by Cuming, is cited by Copeland in his Polypodiace» of 

 tlie Philippines 54, without exact locality. It appears to bc rare. I have 

 specimens from Montalban, Province of Rizal, Luzon, collccted by Loher in 

 March, 1906, that agree exactly with Hoohcr's figvue, except that Lohcr's 

 specimens are smaller, and have bi- to tri-pinnatifid fronds instead of tri- to 

 quadri-pinnatifid ones.
