402 LEAFLETS OF PHITIPPINE BOTANY [Vor. II. ART 
notice the venation, that there are constant differences which, 
i inui free 
once observed, are obvious enough. A. tabacinum has 
veins; A. pariens, reticulate. 
BLECHNUM Linn. 
Blechnum egregium Copel. 
Alt. 1050 m., No. 9695, 
Central Luzon, Mindoro, Mindanao. 
Caudex 30 to 60 em. high, 12 cm. thick. 
Blechnum Patersoni (Spr.) Mett. 
Rich soil in dense woods, alt. 1200 to 1500 m., No. 10066. 
From Luzon southward, 
India to New Zealand. 
Young fronds reddish, 
Blechnum vestitum (BL) Kuhn. 
On mossy soil in crater, alt. 1800 m., No. 9913. 
Mt. Haleon, Mt. Mayon, and Mt. Apo. 
Malaya. 
Caudex erect, stout, 15 em. high. 
DIPLAZIOPSIS C. Chr. 
Diplaziopsis javanica (BL) C. Chr. 
Alt. 1200 m., No. 9605. 
Mt. Apo and Mt. Halcon. 
India to Polynesia. 
Caudex short, erect, bem, thick. A very ample form. 
ASPLENIUM Linn. 
Asplenium Nidus Linn. 
Alt. 1200 m., No. 9830. 
Exactly this form I have not seen before. The fronds 
are 1 to 2 m. long. The base is incomplete but apparently 
like that of A. cymbifolium Christ, which is the original Tham- 
nopteris musaefolia J. Sm., but not A. musaefolium Mett. The 
sori are fine, like those of A. musaefoliwm Mett., but longer, 
but the base is very different. 
Asplenium Phyllitidis Don. 
Large tufts on the basal portion of trees in humid woods, 
alt. 1050 to 1200 m., Nos. 9720, 10357. “‘Tugundbuyoc.”?
