564 APPENDIX. 



Var. semiglaber Rogers. Subglabrous. Armature less uri- 

 formly patent and not quite so unequal. Pan. broader. Fl. 

 more showy. Fr.-sep. often clasping. 



Group XIII. BELL AUDI ANI (GlanduIosiFocke). St. mostly 

 prostrate roundish often pruinose. Armature as scattered as in 

 Koehleriani and very varied but weaker, the prk. being usually 

 slender and in some instances almost reduced to acic. L. 3- 

 nate or 4-5-nate-pedate, green on both sides. Bas, Its. stalked. 

 Stip. filiform, rarely narrowly linear. Pan. mostly less com- 

 posite, occasionally reduced to a raceme. Stkd. gl. and gland- 

 tipped bristles on. pan. usually red or dark purple, mostly very 

 unequal, often considerably exceeding diameter of ped. and 

 hairs on rach. and ped. Usually rather small low-growing 

 plants, occurring chiefly in the woods and thickets of somewhat 

 hilly districts. Many of the sp. very ill-defined and variable. 

 For detailed account of the differences between this group and 

 the Koehleriani see Focke, Syn. JR. G. 355. 



1. Stkd. gl. on pan. conspicuously unequal, often twice as 

 long as diameter of ped. Glaudtipped bristles often numerous. 

 a. Fr.-sep. normally erect or patent (sometimes loosely 

 reflexed in JR. Durotrigum}. 

 (i.) L. chiefly 5-nate. 



It. viridis Kalt. Prk. and prklets fairly many, large-based.

 shallow teeth. Stam. far exceeding sty. Young carp, 

 pubescent.

 long-based. Lts. verv slightly hairy on veins beneath, with 

 deeply incised or lobate teeth. Stam. and sty. subequal. 

 Young carp, thinly hairy. 



(ii.) L. chiefly or wholly 3-nate. 



R. diveziramus P. J. Muell. L. mostly 3-nate. Lts. soft
