cornuque simulat.] Cellule multo majores, ocelli tamen minus con- 
spicui nec tam symmetrice disposita ac L. squamate. 
Foliola fere conveniunt, lateribus tamen incurva, [nee apice recurva ut in 
L. squamata]. 
Perianthia longiora sunt, auriculis valde dilatatis pulchre albo-marginatis, 
contigiis vel etiam paulo imbricantibus. 
Obs. The branches and branchlets are several pairs of leaves apart, 
which leaves room for from 2 to 4 fertile ramuli between two consecutive 
branches; whereas in L. sguamata more than one is never seen. ‘The ? 
flowers are found on the primary branches more frequently than on the- 
stem, but in L. sqwamata are wholly confined to the latter.

A Sticto-Lejeunea differt statura humilore foliis foliolisque minoribus ; 
caule flexuoso minus regulariter pinnato; foliis divergentibus, e cellulis 
axialibus magnis pellucidis moniliatis, falsinerviis (nee tota superficie 
punctatis, sicut in Sticto-Lejeunea), lobulo sat conspicuo recto; foliolis 
minoribus late cuneatis; floribus 9 in ramo longiore terminalibus 
(dichotomialibus); bracteis foliis submajoribus, fere conformibus ; peri- 
anthiis cuneatis obcordato-bilobis (auriculis oblongis complanatis anguste 
alatis), valde compressis, facie antica planis, postica bicarinatis, carinis 
subalatis. 
Sticto-Lejeunea folia habet tota superficie punctata, flores 9 quasi- 
laterales (cladogenos), bracteas minutas, alteram earum equilobam, peri- 
anthium postice obtuse unicarinatum, margine carinisque exalatum ; itaque
