thence pinnatifid, the end serrate-acuminate, pinnulae horizontal, apart 

 or subdistant, oblong, \-\ in. 1. J~§ in. w. the interior ones of the lower 

 pinnae reduced, and the lowest one on the inferior side of the one to two 

 lowest i airs of all absent, free and rounded at the base, becoming gra- 

 dually adnate and closer as the pinnatifid outer part is approached, 

 rounded at the end, throughout crenato-dentate, the teeth 1-2 li. w. ; 

 veins pinnate, the branches open ; sori short, few or many double, 

 reaching halfway to the margin from the midrib ; involucres brown, deli- 

 cately membranous, plain or tumid, eroded. — Lotzea diplazioides, Klotz 

 et Karst. A. Hartianum, Jenm. 



Var. maxima, Jenm. — All parts much larger vestiture and colour 

 similar. 



Infrequent in forests of the middle and higher, though not highest, 

 mountain regions. A plant of very lax habit throughout, furnished 

 beneath, and slightly so above at first, with a rusty glandulose pubes- 

 cence and having short sori and plain or tumid eroded or fimbriated 

 involucres. It is Xo. 1,745 and 1,753 of Linden's Cuban collections, 

 and was gathered in Columbia by Karsten and Moricand and in Vene- 

 zuela by Fendler. In cutting it comes nearest some of the less com- 

 pound forms of striatum from which it differs by its very lax habit, ves- 

 titure and involucres. The variety may be distinct. 



46. Asplenium radica ns, Schk. — Rootstock very stout, erect, reaching 

 \—\\ ft. high, clothed with dark scales at the top; sti:>ites caespitose, 

 erect, stout, channelled, dark deciduously paleaceous at the base ; rachis 

 similar, fronds ample, tripinnatifid, 3-4^ ft. 1 1^-3 ft. w. chartaceous, 

 dark green, paler beneath, naked above, puberulous beneath ; pinnae 

 spreading, subdistant, inferior petiolate. lowest pair usually not or little, 

 reduced, if not largest, 1-lf ft. 1. J-f ft. w. or over, pinnulae approxi- 

 mate the inferior usually more or less stipitate, those above sessile, upper 

 adnate. oblong or ovate-lanceolate, base truncate, apex serrulate-acumi- 

 nate 3-6 in. 1. ftj— 1| in w. cut shallowly or deeply into close oblong 

 blunt or rounded even or crenate segments which are J— § in. 1. 2-4 li. 

 w., veins pinnate simple, or the basal antedor, forked, sori copious, 

 variable 1-2 or 3 li. 1. short of the margins ; involucres flat or slightly 

 raised, membranous, browi ish. 



a. Var. pallidum, Jenm. Fronds much smaller ; pinna? less acuminate, 

 shallowly and broadly lobed, colour light pale green on both sides, : sori 

 and involucres also pale, rachis rather slender. 



b. Var. crenatum, Jenm. — Fronds average size of the type, ultimate 

 segments crenulate -dentate, the strongest tooth situated at the base, 

 almost in the sinus ; uuder surface rather more ciliate. 



c. Var. remotum, Jenm. — Fronds very large, pinnae 1^-2 ft. 1. f-1 

 ft. w. ; pinnulae 5-6 in. 1 1 \ in. b. stipitate deeply pinnatifid ; segments 

 f-1 in. 1. 3-4 li w. broadly rounded; veins forked ; costules and ribs 

 pubescent beneath. 



Frequent in moist regions in forests and shady places, chiefly near 

 streams, from 2,000-4,000 ft alt. ; very variable in size and other features. 

 As intimated under that species, the line is not a very clear one in dealing 

 with herbarium specimens between the more compound states of striatum 

 and this, a was gathered at Second breakfast Spring between Mt Moses 

 and Tweedside, St. Andrew, b in a gully in the Cinchona Plantation on 

 the road to Morce's gap, and c on the banks of the upper sources of the
