the larger fronds, oblong or linear-lanceolate, acuminate, the base 

 truncate or somewhat rounded and sessile, 4-7 in. I., J-l in. b., subentire 

 or with broad appressed lobules or cut to Jth or less to I he axis into 

 rounded, even or cienate close, lobes, which are 2J-3 li. w., rachis 

 strong, channelled, grayish-puberulous ; veins 3-6 to a side, the oppo- 

 site inferior pair uniting at a broad angle and sending a long branch 

 to the sinus, at or below which, usually, 1-2 others join ; sori nearer to 

 the mid vein on the inferior, other, or all the veins ; involucres small 

 and soon obliterated — Polypodium serrulatum, Sw.

 460. Aspidium, Mett. 



a. var. paucipinnatum. — Fronds relatively small and pinnae relatively 

 few, the margins subentire with appressed shallow lobes, colour light, 

 sori usually sparse. 



b. var. angustum. — Fronds medium sized or large ; pinnae narrow, 

 subentire or with shallow appressed lobes ; puberulous, dark -green ; sori 

 usually occupying all the veins from costae to margin. 



Abundant on limestone rocks wherever they crop to the surface all 

 through the island. There is much variation in the size of the fronds, 

 number of pinnae (from dozen) their degree of, or absence of any, 



cutting, the colour (which passes from pale to dark-green), and the 

 paucity or abundance of the sori, the latter varying from a single row 

 along each side of the costae to as many rows as there are veins to bear 

 it. There is no doubt of the presence of the involucre, but it is small 

 and displaced or concealed very early by the ripening sori. There is no 

 absolute and definite line between the forms described. The largest 

 and most lobate state resembles a good deal Polypodium flavopunc- 

 tatum, to which it has often been assigned, but from which the vena- 

 tion and other characters at sight distinguish it. This and its forms are 

 the western analogues of N., amboinense Presl. and N., arbuscula, Desv.
