2. PRioNo-LEJEUNEA MURICATO-SERRULATA, Spruce. 
Hab. In cortice vetusto, supra alias Lejewneas repens, ad fluvium Ramos 
flumini Amazonum tributarium, etiam ad Tauaé prope Para.

Pusilla pallide rufula prostrata; caules pollicares filiformes parce vage 
ramosi. 
Folia dissita erecto-patentia oblique lanceolata—interdum anguste ovalia 
obovatave—abrupte acuta, rarius obtusa, toto margine muricato- 
serrulata ; lobulus 4-plo brevior—aliorum ramorum solum 2-plo 
brevior, aliorum obsoletus—subovatus, basi turgidus, margine inflexo 
subtransverso, apice acuto; cellule minutule subelongatze, pellucide, 
ambitu subopace, pariete incrassato, planes convexwve, subapicales 
tamen marginalesque alte conico-prominule. 
Foliola distantia minuta, foliis 6-plo minora, subrotunda, profunde bifida, 
sinu lato sepe lunulari, segmentis lato-subulatis acutis. 
Flores dioici: ? in ramo brevissimo, folio singulo parvo folioloque infra 
bracteas stipato, terminales, innovatione nulla, vel rarissime brevi 
simplice, suffulti. Braztez folia subexcedentes complicato-bilobe, 
lobis lanceolatis acutis, inferiore duplo minore; bracteola obovato- 
lanceolata, ad 3 bifida, rima angusta, segmentis acutis. 
Obs. This very distinct species affords the only example I have met 
with of a normally determinate short female axis becoming occasionally 
(but very rarely) indeterminate, by putting forth an innovation beneath 
the flower, I did not succeed in finding perianths nor male plants.
