in a generic cover, which when folded ought to be Jin. 

 longer and broader than the sheets on which the specimens 

 are mounted, and of rather stouter quality ; the name of the 

 genus, and, if the genus contain numerous species, the name 

 of the sub-genus or section, should be written at the right-hand 

 corner. 



The genera must now be arranged under their respective 

 natural orders in systematic sequence and placed in the 

 herbarium cabinet, which, as already stated, should be air- 

 tight and dust-tight. A convenient size for the cabinet when 

 demy paper is used is 36in. by 40in. and 21in. deep, outside 

 measurement. This allows of twelve pigeon-holes 12in. by 8in. 

 and 19in. deep. If sliding trays are required the width must 

 be slightly increased. The outer edges of the cabinet should 

 be bevelled inwards so as to allow of the doors being fitted as 

 tightly as possible, and the hinges should fold backwards when 

 required, so as to avoid projecting edges. 



Mosses, Hepatic®, and many Alga? are usually mounted 

 on small sheets, which can be arranged in generic covers of the 

 same size as that adopted for vascular plants : most lichens 

 and hard Fungi should be mounted on small cards placed in 

 shallow trays or drawers on account of the greater thickness 

 of the specimens.

Celmisia macmahoni, n.s. 



A small tufted species densely clothed with white silky 

 hairs. Leaves crowded, forming a dense rosette, lin.-ljin. 

 long, Jin. broad, including the short petiole, lanceolate or 

 oblong-lanceolate, acute or subacute, thick, 5-7-nerved below. 

 Scapes 3in.-5in. long, bracts numerous, linear-obtuse. Heads 

 fin.-lin. in diameter; involucral bracts very numerous; outer 

 acute, villous; inner acuminate, more or less clothed with short 

 brown hairs : rays broad : achenes hispid : pappus very un- 

 equal.

A charming species, most nearly related to G. incana, 

 Hook, f., but easily recognized by the long silky tomentum, 

 which offers a strong contrast to the cottony tomentum of
