Conspectus generum 



I. Cellulee pericentrales transverse subdivisae, ergo pro quoque articulo tubi ceu- 



tralis saltem 2 (Frondes epiphyticae aut saxicolae). 



A. Frons erecta, radiatim constructa. 



Holotrichia Schmitz — Frons demum ubique pilis monosiphoniis simplicibus 



inordinatim obsita. 

 Wilsoncea Schmitz — Frons in regione superiori ramorum pilis quoquoversum 



egredientibus squarruloso-divisis dense obsita. 



B. Frons ssepius decumbens ac plerumque plus minus complanata, dorsiven- 

 traliter constructa. 



Bostrychia Mont. — Frons more distiche ramosa (Species nonnullse in aquis 

 dulcibus inhabitantes).

chidiis 5 (Frons parasitica). 



Colacopsis n. nom. — Fila vegetativa monosiphonia.
