(three times divided to the midrib) hke those of D. antarctlca^ are of the 

 dark green colom- and of the very leathery texture peculiar to the foliage of 

 D. arborescens. Its dimensions are also larger than those of the average 

 D. antarcdca, for the fronds attain 15ft. in length ; the leaflets, stalkless and 

 oblong- spear- shaped, are IJft. to 2ft. long. Gin. to Sin. broad, and furnished 

 with close-set, stalkless, spear-shaped, blunt pinnules ; while their segments, 

 instead of being incised or cleft like those of I), antarctica, are oblong and 

 more or less lobed like those of D. arborescens^ and in the case of the fertile 

 ones also conspicuously contracted. 

 The stalks and rachises (stalks of 

 the leafy portion) of the fronds are, 

 like those of D. arborescens^ woolly 

 or scaly throughout, the main ones 

 being densely clothed at the base 

 with narrow scales of a bright 

 rusty-brown colour. The sori (spore 

 masses), which are large and nearly 

 spherical, like those of D. arbores- 

 cens^ are disposed four to eight to 

 a lobe and occupy only the basal 

 portion of the fertile leaflets, two- 

 thirds of which, in their upper part, 

 usually remain barren. — Nicholson^ fi^. 41. Dicksonia Menziesii

A very handsome, stove Fern, of erect growth, but scarcely arborescent, 

 native of Oahu and Honolulu, Sandwich Islands, and very rarely met with 

 in collections. Its handsome, massive fronds^ produced from a short, upright 

 trunk (Fig. 41), are tripinnate (three times divided to the midrib) and some- 

 what triangular in shape. The lower leaflets, which are the largest, measure
