 Genus XXXV. /3. Lygodium, Sw. Stems slender, scandent, 

 bearing alternate fronds, which by being dichotomous 

 near the base appear like two opposite fronds. Capsules 

 in spikes along the edges of ordinary or modified fronds 

 or part fronds, each capsule separately in the axil of an 

 almost marginal infolded involucre, the involucre of 

 each capsule imbricating over that next above. 

 Widely diffused through Asia, America, Africa, and Austral- 

 asia. 

 L. scanclens : — Each pinna simply pinnate. 

 L. Kerstenii : — Each pinna 2-pinnate or more divided. 



179. Lygodium scandens, Sw. 



Underground stem long, black, wiry, slender, repeatedly 

 branched, rooted abundantly and clothed with shining 

 black lanceolate scales. Scandent stems slender, hard, 

 wiry, glabrous, unbranched, many feet in length, and 

 producing alternate glabrous fronds, 3-6 inches apart. 

 Primary petiole 2 lines long, ending in an abortive scaly 

 bud, and bearing two divaricate pinnae, each 3-6 inches 

 long and simply pinnate. Pinnules jointed on to the 

 short petioles, variable in form, 1-1^- inches long, 

 ^-1 inch wide below, rounded, cordate, or lobed at the 

 base, and tapering to the rounded apex. Margin crenu- 

 late, and in the fertile fronds bearing several irregular 

 segments 1-6 lines long, 1-3 lines wide, several or all of 

 which are modified into capsule-bearing spikes. Ter- 

 minal pinnule usually forked. This species, which 

 occurs in Eastern Asia, Eastern Australia, Australasia, 

 and Tropical Africa, has several forms ; our plant differs 

 considerably from the form most common in cultivation.
