SYNOPSIS OF THE SPECIES. XXIX 



branchlets ; apices hooked inwards ; internodes partially clothed with 

 coloured cells, which extend from the nodes, but leave a colourless band 

 in the centre of each internode. (Tab. CCLXXVI.)

 or without lateral ramuli ; apices straight, spreading ; internodes colourless, 

 the lower thrice as long as broad, upper very short ; dissepiments purple, 

 scarcely swollen ; tetraspores whorled. (Tab. CCXIX.) 



230. diaphanumj filaments setaceous, attenuated upwards, irregularly dichoto-

 narrow, acute axils ; apices slightly incurved ; internodes colourless ; nodes 

 (smooth or hairy) opake, purple ; favellffi near the ends of the branches, in- 

 volucrate ; spores erumpent, whorled. (Tab. C( ( A \ \ 1 V.) 



233. nodosum ; capillary, rigid, dichotomous, fastigiatc ; axils very patent ; 

 articulations pellucid, 4-6 times as long as broad ; dissepiments swollen; 

 tetraspores erumpent, on the outer edge of short ramuli ; favellffi near the 

 tips of short ramuli. (Tab. XC.) 



234. fastigiatum ; capillary, flaccid, dichotomous, level-topped, rosy; axils 

 acute; internodes pellucid, 4-6 times longer than broad, the upper short 

 and coloured ; nodes coated with cells, not swollen; favellffi subterminal, 

 involucrate. (Tab. CCLV.)
