ALOBIELLA. | CEPHALOZIA. 393 
§ 2. Foliola foliis adjecta. 
6. C. acroscypha. Dioica acrocarpa pusilla tenerrima prostrata flagellifera. 
Folia subimbricata subplana ovato-oblonga-lanceolatave obtusata— 
raro retusa vel apice 2-3-crenata—cellulis majusculis elongatis. 
Foliola parva—superiora increscentia—subulata integra bifidave. 
Br. emarginato-2—-4-fide. Per. obtuse trigona, ore breviter 3-6-fida 
edentula. 
7. Husnoti. Dioica cladocarpa, a basi procumbente flagellifera erecta ; 
ramis fastigiatis, apice in sicco sepe hamatis. F. contigua patula 
plana lanceolata subacuta—rarissime bidentula, cellulis majusculis 
elongatis. F'* duplo breviora, linearia, ultra $ bifida. Br. carinate, 
ad } bifid, subdenticulate. Per, triquetro-prismatica, ore setulosa. 
4, CEPHALOZIA INTEGRIFOLIA, Spruce. 
Hab. In sylvis umbrosis fluvii Negro, supra cataractas, et fluvii Uaupés 
ubi in truncis prostratis putrescentibus, rarius ad aggeres umbrosos 
inter muscos, viget; etiam in Andibus Peruvianis super M. Cam- 
pana, alt. 1000™. 
F -4x°3 (in pil. sterili *8x°5); cellule ¥—)5; br 16x'6; per 25x 4, 
30 xX 5", 
Majuscula albido-viridis, margaritaceo-nitens, strato tenui late effusa. 
Caules 14-pollicares prostrati tenues subramosi, supra subplani, 
subtus conyexi, strato corticali pellucido induti; cellule corticales 
9-10-seriate compresso-cylindrice, interne 10-12-seriate triplo 
angustiores, sectione zequilateree. Rami omnes postici, alii flagelli- 
formes subaphylli radicelliferi. 
Folia vel dissita, vel subimbricata, vel szpissime valvatim contigua, 
longitudinaliter, vel (basi antica longius decurrentia) parum oblique 
inserta, oblonga rhomboideave, apice rotundata vel suboblique trun- 
cata, rarissime rudimentarie bidentata; inferiora superioraque sepe 
sensim minora (unde rami elongato-lanceolati fiunt); cellule magne 
oblongo-hexagonz leptodermes pellucide. 
Flores dioici: ¢ postici, ramo brevi constantes. Bractee 3-4-juge, 
intime variabiles, foliis 2-4plo longiores, lanceolate, ad 4 bipartite, 
basin versus angulatze, laciniis a basi late subulata longe sensimque 
attenuatis. 
Perianthia bracteas alte superantia, lineari-subulata-lanceolatave, trigona, 
ore breviuscule trifida, segmentis bi-trifidis, laciniis ciliiformibus 
inequalibus. Capsula oblongo-cylindracea, duplo longior quam lata. 
Amenta ¢ ramulo parvo constantia, albida, raro rami foliosi basin 
apicemve tenentia; bractee plurijuge conferte assurgenti-secunde 
parvee subquadrate emarginate, utroque apice cellula unica magna 
seepe apiculate, monandre. 
Obs. Plante foliis ex parte in frondem pinnatifidam plus minus alte 
connatis rarissime adveniunt.—Folium incubwin inter normalia succuba 
interpositum aliquando invenitur. Ceterum, nostra plantula, quoad 
aspectum, Calypogeiam (Kantiam) potius quam Cephaloziam refert. 
5. CEPHALOZIA MACELLA, Spruce. 
Hab. In sylva Amazonica, prope Santarem, ad fl. Tapajoz ostia, super 
ligna putrescentia in palude; etiam ad San Carlos del Rio Negro.
