LEPIDOZIA. 365 
florescentia monoica; ramificatione vaga ; foliis solum 2-3-partitis, la- 
ciniis lanceolatis; ete. 
Obs. In consequence of the exactly transversal insertion of the leaves, 
and their concavity, they are in reality neither succubous nor incubous. 
Each leaf lies partly over and partly under the next upper leaf, when the 
stem or branch is laid flat; but stands exactly underneath it (like one 
cup under another) when the stem or branch is set upright. 
10. LEPIDOZIA AMAZONICA, Spruce. 
Hab. in solo rubro subquarzoso, sub fruticum umbra, ad Mandos, fl. 
Negro ostiis proxima: rara et solum sterilis. 
HAD: 6 as JF 08™™. 
Minuta badia prostrata intricata. Caules }-pollicares pauciramei—raro 
subpinnati, basi rhizomatosi flexuosi divisi subaphylli interdum 
postice flagelliferi; rami laterales basi subnudi. 
Folia transversa confertiuscula, late patentia tamen, apice incurvula, cune- 
ata 3-partita; cruribus subulatis obtusis, 2 lateralibus majoribus 
dimidio infero 2 cellulas, supero 1 cellulam latis, crure antico 
breviore et angustiore cauli parallelo et subappresso; cellule 
minutule rectangulares vel subquadratz tuberculis asperate. Limbus 
folii basalis ad crura longiora 2 cellulas, antice tamen 1 cellulam 
solam, latus; crura lateralia 6—7cell. longa. 
Foliola duplo breviora caule velata, bipartita, cruribus 1 cell. latis, altero 
duplo fere breviore. Rhizina vix ulla nisi pauca ad caulis basin 
rhizomatosam. 
Obs. The underleaves are contiguous at the base, on the side of the 
longer segment, to the adjacent leaf, but distant from the leaf on the 
opposite side of the stem. L. capillaris Sw. has the leaves three times as 
long, less deeply cloven, and (like the underleaves) often 4-cleft; besides, 
like nearly all other tropical Lepidoziew, it is a mountain plant. L. 
amazonica is the only species known to me which descends very nearly 
to the sea-level within the tropics. It is scarcely necessary to add that 
our L. setacea seems abundantly distinct in the pinnate or bipinnate 
stems, the less deeply cloven leaves (only to within 3-5 cells of the base), 
the segments wider upwards, and the symmetrical 3-4-cleft underleaves.
