Foliola foliis 2-3-plo—in sp. pusillis 4~7-plo—minora, raro majuscula, 
in nulla foliis ipsis equimagna, subrotunda vel late ovalia, raro 
subangustiora, fere vy. usque ad 4 bifida—in paucis sp. ad # usque 
—laciniis ovatis lanceolatisve perraro subulatis, pro more subacutis, 
nunquam late obtusatis, integerrima v. rarissime utrinque 1-dentata. 
Haustoria fascize-vel seope-formia. 
Flores in plurimis monoici, in paucis dioici: in ramo, raro in ipso 
caule, terminales, innovatione simplice, v. (aliarum specierum) pro- 
lifera, suffulti, raro dichotomiales. Bracteze foliis subsequilongz. 
angustiores, suberectee—necdecurvo-hamatz nec distichepatentissima 
—integerrimee, pro more lobulatze, lobulo,parvo, raro nullo; bracteoli 
seepissime libera, angusta—2-3-plo longior quam lata—in perpaucis 
fere tam lata quam longa—apice brevissime v. ad 4 bifida. 
Perianthia *35-1°1™™ longa, plerumque emersa, plus minus pyriformia 
obovatave, rostellata, paulo compressa—in perpaucis magis com- 
pressa apiceque obcordata, 5-carinata, carinis raro peracutis, in ple-

Andreecia perseepe ramulo tenui cauligeno constantia, rarius in ramo 
terminalia; bracteze pauci-raro pluri-juge, parve, im paucis sp. 
majusculze, in nulla foliis equimagne, diandre. 
Hab., in zona tropica fere semper arborea, raro rupestris, sepe in foliis 
vivis, palmarum precipue, et in filicibus, haud in truncis putridis nisi 
supra alias hepaticas et muscos; in zonis temperatis autem perseepe ru-

Distr. In America eequatoriali 30 species (plerasque novas) legi, 
quarum 11Megalostipas, omnes montanas vel etiam subalpinas, in Andi- 
bus inter 1500 et 3500™ alt. crescentes, preter Hu.-L. flava Sw., species per 
totam planitiem sylvaticam dispersa, in Audibus nullibi ad 1500™ usque 
ascendens. Microstipe erant 6 species, quarum 4 in planitie solum 
observavi, ceteree 2 in Andium radicibus alt. 500™ vix attingentes ; 
Planilobe 7 species, quarum 2 in Andibus, ad alt. 2200™ usque, supra 
suffrutices vigebant; czeterze solum in planitie, truncos vetustos et filices 
diligentes, earum una, Hu-L. inundata n. sp., cum ejus var. fontinaloides, 
ad arborum truncos ramosque fluviorum Negro et Uaupés irrigatos, 
seepe barbam pendulam sistens, Hydropogon fontinaloides Hook. fluvio- 
rum vicinorum Casiquiari et Orinoco simulans. Cardianthe speciebus 
sub 6 constabant, omnes in planitie Amazonica vigentes, una sola etiam 
in Andium radicibus vix supra 500™ alt. visa fuit. 
Eu-L. serpyllifolia, cam varietatibus suis in hemispheera boreali late 
dispersa, “‘ cosmopolitana” ab auctoribus dicta, in America equatoriali 
mihi nullibi obvia fuit. Specimina tropico-asiatica in herb. Hook. sub 
nom. L. serpyllifolie asservata, L. flave var. (=L. thymifolia N.) ex p. 
videntur. Species 3 v. 4, L. serpyllifoliew arcte affines, in Europa et 
America boreali temperata crescunt, inclusa L. flava, extra tropicos solum 
ad Killarney Hiberniz inventa.—Aliz plurime Hu-Lejewnee in libris de- 
criptee sunt, maxima parte America tropica indigene, pauce Africane, 
Indice, Malayane vel Australasice.,
