pound, irregularly pinnate or secundly ramulose, the divisions erecto-patent, some- 

 times opposite, frequently secund, the upper ones piano-compressed ; ultimate 

 ramuli filiform or subulate, acute, not tapering at base, very erect, unequal, lono- 

 and short intermingled. 



Hab. Golden Gate, Capt. Pike. (50 in part, 78.) (v. s. in Herb. T. C. D.) 



Frond 3 or 4 inches high, and as much in the expansion of the branches, stipi- 

 tate, distichously branched in a palmato-flabelliform manner for a short distance 

 above tlie base. Branches half a line to a line in breadth, compressed, sometimes 

 nearly flat, sometimes approaching terete, very irregular in position, spreading, 

 sub-simple and rather naked in the lower part, closely branched and repeatedly 

 divided above. Lesser branches opposite, alternate or secund, small and large 

 branches irregularly consecutive, somewhat pinnate, once or twice compounded. 

 RamuU very frequently secund, of very unequal lengths, filiform or setaceous, 

 acute, ver}' erect. Colour, a brown-red. Substance, cartilaginous and firm. Fruit 

 unkno^\^l. A cross section of a small branch is a narrow ellipse, somewhat 

 attenuated at the ends of the longer axis ; there is a large central or axial tube, 

 and two or more lesser tubes in the line of the longer axis ; there is a narrow rim 

 of minute, peripheric cells, and the whole of the interior space is filled with minute, 

 endochromatic cells, being the cross cutting of longitudinal filaments. A longitu- 

 dinal section shows a central long-jointed filament ; a thin periphery of two other 

 rows of minute coloured cells ; and the intervening space formed of a very dense 

 plexus of longitudinal filaments passing off towards the periphery into an imper- 

 fectly defined stratum of small, angular coloured cells. The central tube easily 

 escapes observation in a longitudinal slice, unless the cutting be exactly through 

 the middle of the fi-ond.
