A. (Diplazium) japonicum— Dip-laz'-I-um ■ jap-on'-ic-um (Japanese), 

 Thunberg. 



A greenhouse species, of small dimensions, native of Japan, China, and 

 the Himalayas ; distinct from most others through the creeping nature of the 

 slender rhizome from which its fronds, 9in. to loin, long and 4in. to Gin. 

 broad, are produced. The peculiar straw-colour of the stipites (stalks) is also 

 a distinguishing character of these fronds, which are furnished with eight to 

 ten leaflets cut down in the lower part into close, oblong, slightly-toothed 

 lobes of papery texture and bright green on both surfaces. The sori (spore 

 masses) reach two-thirds of the way to the edge on both margins. This plant 

 is in Hooker's " Species Filicum," hi., p. 251, described as A. Schkuhrii, 

 under which name it is frequently met with in private collections. 



A. j aYanicum— jav-an'-ic-um (from Java). Synonymous with Allantodia 

 Brunoniana. 



A. (Diplazium) Klotzschii— Dip-laz'-i-mn ; Klotzsch'-i-i (Klotzsch's-), 

 Mettenius. 



This stove species, of very large dimensions, is a native of Columbia and 

 Venezuela. It is of an almost arborescent nature, and its ample fronds, 3ft. 

 to 5ft. long and 9in. to 18in. broad, are borne on strong, upright stalks of 

 a dark brown colour and scaly at their base ; they are furnished with leaflets 

 6in. to 9in. long, 3in, to 4in. broad, deep green, and of a papery texture. 

 The leaflets are divided into leafits 2in. to Sin. long, which are subdivided 

 into slightly-toothed lobes. The linear-oblong spore masses fall short of the 

 edge of the lobes. — Hooker, Species Filicum, hi., p. 263. 



A. (Euasplenium) Kraussii— Eu-as-ple'-ni-um ; Kraus'-si-i (Krauss's), 

 Moore. 



A small-growing, greenhouse plant, native of Natal, and so closely related 

 to A. viride as to look like a form of that species. The fronds, 3in. to 

 4in. long and Jin. broad, are furnished with about twelve pairs of sessile 

 pinnse (stalkless leaflets), which have their upper edge sharply toothed, while 

 their lower one is smooth. The linear-oblong sori (spore masses) are disposed 

 from one to three to each leaflet and occupy an oblique position. — Hooker, 

 Species Filicum, hi., p. 147, t. 180a.
