Alexander W. Evans, 



present plant formed a part of Svvartz's aggregate species Junger- 

 mannia obscura. It is a species of wide variability and has been 

 carefully described by Spruce. His description, however, differs 

 in certain respects from the later description of Stephani. 



The plants are of large size and 

 grow in rather loose mats, some- 

 :\ tXT V ^ times on rocks or banks, some- 

 times on trees. They show a wide 

 range of color, varying from a 

 pale yellowish green to a deep 

 purplish black. The stems are 

 at first prostrate, without clinging 

 very closely to the substratum; 

 later on they separate still more 

 and assume a spreading or as- 

 cending position. On robust 

 sterile shoots the branches arc 

 usually short and simple, so that 

 the shoot is distinctly pinnate. 

 On fertile shoots there is a strong 

 tendency for the later branches 

 to elongate and become sub- 

 divided, thus giving the shoot a 

 flabellate appearance, and the 

 growth of such a shoot is usually 

 limited by the development of 

 the sexual branches. 



The leaves are imbricated and 

 the lobes are strongly convex 

 and widely spreading but not 

 squarrose (Fig. 10, A). They are 

 ovate in outline, measuring about 

 1.6 mm. in length and 1.2 mm. 

 in width ; the apex is rounded, 

 and the whole apical region is 

 usually distinctly revolute. The 

 antical portion arches across the axis and is cordate or auriculate 

 at the base (Fig. 10, B), although the auricles never reach the high 

 degreee of development found in F. gihhosa. The postical margin, 

 between the revolute apical portion and the junction with the lobule, 

 is more or less strongly crispate. 



Tlie lobule measures about 0.75 mm. in length and 0.35 mm.
