with the Cicutarice by T. latifolia.

Copeland 217, 1396; Topping, 533, Borden, P. B. 1959; Mindanao, Suri- 
gao, Bolster 386 ; Mt. Apo, Copeland 1468. 
15. Tectaria Christii Copel. nom. nov. 
Aspidium coadunatum Wall, non Kaulfuss. For a diagnosis of this 
plant see Christ. Phil. Journ. Sc. 2 C. (1907) 187. 
Luzon, Bontoc, Copeland 1899 ; Benguet, Topping 229 ; Mindoro,

16. Tectaria irregularis (Presl) Copel. nom. nov. 
Polypodium Presl, Eel. Haenk. 25. 1825, Plate IV Fig. 3; P. pteroides 
Presl. 1. c. fig. 4; Aspidium difforme Bl., Enumeratio 160, 1828; Poly- 
podium Brogniartii Bory. Dup. Voy. Bot. I (1828) 263; Phegopteris 
macrodonta (Reinw.) Mett. Pheg. & Aspid. 1858". No. 68: Polypodium 
Cumingianum (Presl.) Hooker Sp. Fil. 5 (1864) 103; Aspidium Whit- 
fordi Copel. Perkins’ Fragmenta 176, 1905. 
Easy as it is to distinguish the extremes of the forms combined here, 
and to find diagnostic characters which look valid when only the extremes 
are considered, the differences are found inconstant and the gaps are 
bridged over with the accumulation of many specimens. In our herbaria 
this accumulation has reached the point where I can no longer see a good 
specific distinction between any one of them and some other. In 
place of the hitherto recognized species,, we will better recognize 3 or 4 
inconstant varieties. 
a. Var. euirregularis. 
Frond simply pinnate : sori small and very numerous, sometimes much 
more so even than Presl figured, and irregularly scattered. Presl, surely 
in error, credits the type to Mexico. 
Culion, Merrill 665; Mindanao, Surigao, Bolster 220; Camp Keitliley, 
Clemens s. n. ; San Ramon, Copeland 1569. 
Simply pinnate fronds with the sori more like those of the next variety 
are : Foxwortliy B. S. 1962, Pampanga ; Topping 424, Elmer 6684, Mt. 
Mariveles; Copeland s. n. Mt. Maquiling. Elmer 6230, is simple, but 
has the slender upper pinnae of var. Brogniartii.
