Gen. Car. Frond filiform, decompound, articulated, one-tubed ; the znder- 
nodes naked or coated with minute cellules; the nodes clothed with 
opposite or whorled articulated ramelli. Wructification : 1, cystocarps 
terminating short branches, involucrated by the uppermost, whorled 
ramelli, and consisting of tufts of pear-shaped pedicellate spores and 
slender paranemata; 2, naked, triangularly parted ¢etraspores, borne 
on the sides of the whorled ramellimWraneetta (4g.), in honour 
of Baron v. Wrangel, a Swedish naturalist. 
Frons filiformis, decomposita, articulata, monosiphonia, nuda v. cellulis corticata, 
verticillis ramellorum ad genicula onusta. Fruct.: 1, cystocarpia ramos 
terminantia, ramellis supremis wvolucrata, fasciculis numerosis sporarum 
pyriformium pedicellatarum et paranematibus tenuibus constantia ; 2, tetra- 
spore nude, triangule divise, ad ramellos sessiles. 
Wrancetta clavigera; frond cartilaginous, corticated, decompound-pin- 
nate, pinne and pinnule alternate, spreading, throughout densely 
whorled with imbricating multifid ramelli, the younger branches club- 
shaped (in outline); ramelli alternately pinnato-multifid, the apices 
acute; articulations 2-8 times as long as broad; cystocarps termi- 
nating short, club-shaped, hirsute pinnules.

Descr. Loot clothed with woolly fibres. Frond 6-12 inches long, and as much 
in the spread of the branches, either once, twice, or thrice alternately or 
irregularly pinnate ; the main stems mostly simple, sometimes forked ; the 
primary pinne very widely spreading, closely set, of unequal length, long 
and short intermixed, the longer ones again pinnated. All parts of the 
frond, except those which are worn by age and exposure, are densely
