106. urceolataj rigid, setaceous, full-red, loosely bundled; branches dichoto- 

 mous, with scattered patent or reflexed ramuli ; articulations 3-5 times 

 as long as broad ; dissepiments pellucid ; capsules pitcher-shaped, constricted 

 at the mouth. (Tab. CLXVII.) 



107. formosa; flaccid, exceedingly slender, full red, densely tufted ; branches 

 dichotomous, with scattered, patent ramuli; articulations 5-10 times as 

 long as broad ; dissepiments pellucid ; capsules pitcher-shaped, constricted 

 at the mouth. (Tab. CLXVIII.) 



(P.stricta, Harv. Man. p. 83, seems to be the young of this species?) 



108. pulvinata; densely tufted; filaments creeping, throwing up erect, irregu- 

 larly dichotomous stems, whose branches bear a few short, recurved ramuli ; 

 articulations 3-4 times as 'Jong as broad ; capsules urn-shaped, stalked. 

 (Tab. CII. B.) 



109. fibrataj setaceous below, attenuated and capillary above, flaccid, gela- 

 tinous, alternately branched, with dichotomous, pencilled lesser branches, 

 whose tips are remarkably fibrilliferous ; axils patent; articulations of 

 the branches 4-6 times longer than broad ; capsules ovate, stalked. 

 (Tab. CCVIII.) 



110. spinulosa; articulate throughout; rigid, branched from the base, branches 

 divaricate, decompound ; ramuli short, spine-like, spreading ; articulations 

 as long as broad, three-striate. (Tab. CCCXX.) 



111. Richardsonij stem cartilaginous, setaceous; branches alternate, long, 

 divaricated, set above with very patent, straight, forked ramuli ; articula- 

 tions 2-3 times longer than broad, veiny ; tubes 5 ; capsules sessile, broadly 

 ovate. (Tab. X.) 



112. Griffithsiana ; stem alternately branched, rigid ; branches subsimple, with 

 dichotomous or alternately multifid pencilled, slender ramuli ; articulations 

 once and half as long as broad, 3-4-striate ; siphons four primary, with 

 four external, secondary ; capsules sessile. (Tab. CCXXVTII.) 



113. elongellaj setaceous, rigid below, flaccid above, dichotomous, with very 

 patent axils ; upper branches decomposed into multifid, pencilled, rose-red 

 ramuli ; articulations about as long as broad, 2-3 -striate, the tubes very 

 wide and dissepiments pellucid; capsules ovate, stalked. (Tab. CXLVI.) 



* * Primary tubes 4 ; stem and branches subopake, or inarticulate. 



114. elongata; robust, cartilaginous, irregularly divided ; ramuli pencilled, ca- 

 pillary, multifid, attenuated at base and apex ; articulations once and half 

 as long as broad, those of the stem and branches reticulated with veins ; 

 siphons four. (Tab. CCXCII. and CCXCIII.) 



115. violacea; brown-red, purple, or sanguineous; stem inarticulate, veiny, 

 robust, alternately branched ; branches decompound, feathery, the ultimate 

 ramuli very slender, multifid, fibrilliferous ; articulations of the ramuli two- 

 striate, 2-4 times as long as broad ; capsules ovate. (Tab. CCIX.)
