Var. Newbouldii (Bab.) ? St. furrowed, paler, not glaucous, 

 densely hairy. Term. It. shorter, roundish-obovate with long 

 point. 



Var. Bloxamianus Colem. St. glabrous or nearly so, densely 

 glandular. Term. It. roundish-obovate with rather short 

 point. 



R. regillus A. Ley. St. bluntly angled, pale, glaucous, hairy, 

 very leafy. Term. It. oblong, with long cuspidate point. 



(It. radula, var. echinatoides Rogers.) See above, in 

 Subsection a. 



2. Stkd. gl. and numerous acic. on pan.-rach. and ped., 

 though rarely long, usually far exceeding the close felt or very 

 short hairs. Stkd. gl. and acic. on st. more thinly and unequally 

 scattered, sometimes nearly absent. 



R. podophyllus P. J. Muell. St. bluntly angled, dark, 

 usually subglabrous. Term. It. oval-oblong, with rather short

(R. adenanthus Boul. & Gill.) See Group VIII., Eyrecjii. 

 (R. infecundus Rogers.) See Group XII., Koehleriani. 

 (R.fuscm Wh. & N.) See Group XL, Sub-Bellardiani. 



Group X. SuB-KoEHLERiANi. Distinguished from the 

 true Radulce by the strong larger prk. being somewhat more 

 unequal and less strictly confined to the angles of the st., and 

 by the general armature of prklets, acic., etc., being also rather 

 less uniform in length and stoutness ; while they differ from 

 the true Koehleriani by the less graduated series of glandtipped 

 organs and the comparative rarity with which such organs 

 exceed the hairs on pan.-rachis and ped. 



1. Glandtipped organs on pan.-rach. almost wholly sunken in 

 the patent hairs. 



a. Fr.-sep. subpatent, at least for a time. Lts. thick. 



(i.) Lts. with whitish felt beneath. Starn. long. 

 R. Griffithianus Rogers. St. and very unequal prk. deep 

 red. Term. It. roundish-obovate-acuminate. Pan. rather 

 narrow, lax, nearly cylindrical. 



(ii.) Lts. usually softly hairy beneath. Stam. rather 

 short. 



R. Babingtonii Bell Salt. St. and subequal prk. fuscous. 

 Term. It. oblong-oval-cuspidate. Pan. broad, cylindrical- 

 truncate, with patent branches and acicular prk.
