{R. radula, var. echinatoides Rogers.) See above, in 
Subsection a. 
2. Stkd. gl. and numerous acic. on pan.-rach. and ped.,

(R. infecundus Rogers.) See Group XII., Koehleriani. 
(R.ficscus Wh. & N.) See Group XL, Sub-Bellardiani. 
Group X. SuB-KoEHLERiANi. Distinguished from the 
true Radxdm 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 diifer 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. Stam. long.

red. Term. It. roundish-obovate-acuminate. Pan. rather 
narrow, lax, nearly cylindrical.
