NEPHBOBIUM, 



NePHRODIUM GL iNDULOSUM. (J. Sm.) Fronds coriaceo-membranaceous pinnate, glabrous on both sides, pinnaa 

 alternate sessile from a broad truncated base about 6 inches long and an inch to an inch and a quarter broad, gradually and 

 rather long acuminated, covered with small glandular tubercles on both sides, coarsely lobato-serrate, serratures falcate acute, 

 veins 9-10 pair generally all anastomosing (except the 2-3 upper pair in the serratures), and the excurrent veinlets joined through- 

 out and forming a very prominent flexuose pseudo costule, the lower pair of veins or one of them is sometimes free, and the 

 excurrent veinlet is also sometimes free in 1 to 4 of the lower areoles, sori large situated a little below the middle of each vein, 

 indusium very apparent reniform ;— Nephrodium ;— J. Sm. in Book. Jouvn. o/Bot.,p. 411 ;— Aspidium ;— Bl. En. Fil. Jew., p. 144 ? 

 Hook. Sp. Fil iv. 76. 



The specimen figured is from the Himalayas, (Mr. Oldham). I am not quite sure whether I have rightly named this and 

 the following species, several species of the genus Nephrodium are very closely allied to each other, and it is impossible to say that 

 intermediate forms do not exist ; both these species are closely allied to N. abruptum Fresl, the specimens here figured have the 

 fertile and sterile fronds exactly similar, and Sir W. Hooker describes the N. glandulosum. J. Sm. and lineatum Fresl. as having 

 the fronds dimorphous, or subdimorphous. I do not, however, attach any importance to this fact, as I have often found N. abruptum 

 with the fronds dimorphous, or with broad sterile pinnae and contracted fertile pinnae on the same frond, or with both sterile and 

 ertile pinnse exactly similar, and I have constantly observed the same tendency in many other genera with dimorphous fronds,
