Flores Q Ptychanthi Javanict (zeque ace Pt. Moluccensis, intermediique, 
que mere prioris varietates videntur) in ramo brevi terminales, inno- 
vatione simplice mascula suffulti; P#. sudcate autem in ramo primum 
furcato, dein alternatim innovando positi sunt, eodem fere modo ac in

Elatiuscula, late depresso-czespitosa, apice virescens, inferne fulva fusces- 
censve. Caudex longe repens denudatus subramosus, seepe multi- 
caulis. Caules 1-3-pollicares validi assurgentes parum ramosi, vel 
subregulariter pinnati; alii rami apice florentes, innovando-prolongati; 
alit (pauci) flagellares parvifolit decurvt radicantes. 
Folia mediocria (0°9-1'7™™ longa) conferta, humida distiche pectinatim 
patula, sicca pro more decurvo-convoluta, plus minus lingueeformia, 
apice triangulari subacuta obtusave—raro rotundata vel apiculata, e 
margine toto postico (apice excepto) late incurvo subfalcata, seepeque 
ad speciem ligulata; lobulus 3-4-plo brevior, lineari-rectangularis 
rhomboideusve subinflatus, margine plano integerrimo, apice acuto 
bidentellove; cellule plerumque parvee minutuleeve pariete Incrassato 
utriculo sepe constricto, subopace pellucideve, inferiores majores 
magisque elongate. 
Foliola foliis paulo (raro duplo) breviora, plerumque sublongiora quam 
lata, cuneata—basi angusta, apice dilatata—retusa vel late emarginata, 
integerrima vel apicem versus subdenticulata. 
Flores monoici vel dioici: 2 in eaule ramove, apice iteratim monotrope 
innovato, terminales, ad speciem seriatim secundi, conferti—inter- 
dum creberrimi—rarissime dichotomiales. Bractez foliis subeequales, 
acutiores, integerrime vel serrulatie, lobulo in aliis obcordato-bifidulo; 
bracteola angustior, emarginata vel breviter bifida. 
Perianthia sepius emersa, prismatico-triquetra, pyriformia obovatave, 
raro linearia, apice obtuse truncato rostellata, carinis vel nudis vel 
plus minus alatis, ala in paucis latiuscula et laciniata vel ciliata, in 
unica duplicata; rarissime, plicis ad latera interpositis, 7-10-pli- 
cata-carinatave. Calyptra perianthio sat brevior rufa firmiuscula, 
clavato-pyriformis, ab apice ultra medium in valvulas 3, quarum 
duas sublatiores ovales, tertiam lanceolatam, dehiscens. Capsula 
subglobosa ultra dimidium quadrivalvis; valvule pallide rufz re- 
curvulz facie interna papillosa et ab apice ad } longit. elateribus 
tenuibus unispiris, apice dilatato-truncatis, sparse obsite. Pedicellus 
perianthio parum longior, ex ejusdem carina postica apice hiante ex- 
trusus, pallidus crassus, cellulis majusculis cylindricis collateralibus 
21-seriatis (5 in diametro, axialibus uniseriatis) conflatus, siccando 
ad cellularum apices nodoso prominulus, ad internodos constrictus, 
quasi-articulatus, non autem geniculatus.
