560 APPENDIX. 



topped with long ascending lower branches. Sep. patent or 

 subpatent for a time, soon loosely reflexed. 



(R. mutabiiis Genev.) See below in subsection b. 

 b. Fr.-sep. reflexed. Lts. rather thin. Stam. long. 



(i.) Lts. thinly hairy beneath. 



R. melanodermis Focke. St. and rather unequal prk. 

 blackish-purple. Lts. very plicate, green ; term, obovate- 

 truncate. Pan. narrow cylindrical. 



R. Babingtonii Bell Salt., var. phyllothyrsus (Frider.). St. 

 fuscous. Term. It. obovate-acuminate. Pan. broad, with 

 strong falcate prk. and several simple 1. 



(For typical R. Babingtonii see above in Subsection a.} 



(ii.) Lts. softly hairy or with rather close felt beneath, 

 at least when young. 



R. cavatifolius P. J. Muell. St. and rather unequal prk. 

 pale or reddish-brown. Lts. yellowish-green ; term, broadly 

 cordate-ovate-acuminate. Pan. nearly cylindrical, truncate. 



R. tmitabilis Genev. Lts. very long and narrow, deeply 

 incised, with close pale felt beneath ; term, narrowed at both 

 ends. Pan. very large, nearly cylindrical. 



(For subsp. nemorosus Genev. see below, in Section 2.) 



2. Glandtipped organs on pan.-rach. more unequal, rather 

 frequently exceeding the short hairs or felt. 



a. Fr.-sep. reflexed, with rather close felt. 



R. Lejeunei Wh. & N. Lts. thin, light green ; term, 

 obovate-rhomboidal. Pan. loosely pyramidal, with slender 

 unequal armature. Pet. broad, bright pink. 



Subsp. ericetorum (Lefv.). Stronger. Lts. with longer 

 point, grey-felted beneath. Pan. very long, pyramidal- 

 corymbose, more prickly and glandular. Pet. narrow, white or 

 pinkish. 



b. Sep. rising on fall of pet. 



R. mutabiiis Genev., subsp. nemorosus Genev. Lts. thick, 

 with subvelyety felt beneath ; term, cordate-ovate-acuminate. 

 Pan. pyramidal, interrupted. 



(For typical R. mutabiiis see above, in Section 1.) 



Group XI. SUB-BELLARDIANI. The larger prk. not so strong 

 as in Groups IX. and X. and rather more scattered and unequal. 

 St. often lees angular. Near the true Bellardiani, but usually 

 stouter with a less graduated series of prk. and other arms and 

 a greater tendency to compound branches in the lower half of 

 the pan. Several of the plants in Section II. of Bellardiani 

 however would hardly be out of place among the Sub-Bel- 

 lardiani*
