M. Drummondii, 4. n Linnea, xxv. 721.—9Ends of the 
rhizome under ne of the Eaton and involucres more or less silky- 
hairy. Stipes of the barren fronds usually long and slender; leaflets 
broadly obovate-cuneate or fan-shaped, more or less crenate or shortly 
lobed or rarely quite entire. Involueres larger than in any of the 
Peping species, the stipes or peduncles clustered, free from the base, 
to 1$ or rarely 2 in. long.— M. Muelleri, A. as in Linnea, xxv. 721;

A. Bra d in the Kew and other herbaria distinguished several varieties upon 
characters which I fail to appreciate, although he afterwards raised them into ten 
distinct species, M. Howittiana, M. sericea, M. Muelleri, M. macra, M. oxaloides, M.

and base of the involucres vary much in their relative degree of prominence, but 
appear to me to show no constancy in this respect even on the same plant. 
2. PILULARIA, Linn. 
Rhizome filiform, creeping, rooting at the nodes. Barren fronds 
reduced to a filiform stipes, few or clustered at ie nodes. Involucres 
solitary at the nodes, sessile or shortly stipitate, globular. Sori 2 to 4, 
vertically adnate, their indusia at first pulpy at length membranous, 
involuere into 2 to 4 cells. pore-cases numerous, the lower ones in 
each sorus macrosporangia, the upper ones g Ra Gainers and much 
more numerous.

fronds of a bright green like the leaves of Isoetes, varying from 1 to 3
