THE SOUTH AFRICAN GERBERAS. 



241 



long, f-ij inch wide, thickly coriaceous, more thickly felted below 

 than in the type ; margin obsoletely dentate. Involucral bracts 

 obviously black-tipped. 



Distribution. Coast Region. Worcester Div. : Dutoit's Kloof, 

 2000-3000 feet, Oct. -J an., Drege ! Caledon Div. : Zwartberg, Zeyher ! 



Var. POLYGLOSSA, De Candolle, I.e. 



Syn. Arnica cordata, E. Meyer ex De Candolle Prod. vii. 16, nop. 

 Thunberg. 



Leaves oblong-elliptic, cordate or obHquely cordate at the base, 

 2-3 inches long, f-i| inch broad. 



Distribution. Coast Region. Worcester Div. : Dutoit's Kloof, 

 2000-3000 feet, Oct.- J an., Drege ! 



G. tomentosa occupies a position intermediate between G. aspleni- 

 folia and G. ferruginea, but may invariably be distinguished by the 

 extreme paucit};- or total absence of the scape-scales v/hich charac- 

 terize those two species. It is a variable plant difficult of system- 

 atic limitation, but De Candolle recognized two varieties which 

 differ solely in leaf characters. As in the preceding species, the ray- 

 florets are white above and reddish underneath. The distribution 

 of the plant and its varieties is suggested by the collectors' citations. 



Gerbera integralis, Sonder in Harv. & Sond. Fl. Cap. iii. 520 

 (1865) ; Bolus & Dod in Trans. Phil. Soc. S. AJr. XIV. iii. 289 (1903). 



Leaves tufted, nine to fifteen, wholly glabrous except for the sheath- 

 ing white cobwebby petiolar base, ascending, rarely spreading, borne on 

 a broadish and flatfish yellowish dorsally slightly keeled or convex 

 petiole |-5 inches long ; blade ovate-oblong, or ovate, obtuse or rounded, 

 narrowing abruptly, then gradually into the petiole, f-3i inches long, 

 |— if inch broad, leathery, entirely glabrous, light lustrous green above, 

 much paler and dull below, the midrib and its three to seven pairs of 

 lateral veins most prominent on the lower surface ; margin wavy, 

 sHghtly revolute, entire or irregularly sinuate basally, or minutely 

 toothed at distant and irregular intervals. Scapes solitary or in pairs, 

 slender, 6-14 inches long, terete, longitudinally striate, brownish, 

 glabrous, studded with small lanceolate-subulate bracts at intervals. 

 Involucral bracts glabrous, 2-3-seriate, acute or acutely acuminate, 

 subapically and dorsally keeled. Flower-heads averaging 1J-2 inches 

 in diameter ray-florets white above, reddish beneath, 2-3-toothed 

 apically. Pappus cream or pale brown. 



Hab. Coast Region. Cape Div. : Cape Flats near Rondebosch, 

 Dec. 14, 1810, Burchell, 219! Cape Flats, E cklon diud Zeyher ex 

 Harvey ; near Cape Town, Harvey ! Table Mountain, Lower Plateau, 

 Feb. 23, 1896, Wolley Dod, 874 ! 



An exceedingly uncommon and moreover acceptable species, easily 

 recognized from its allies by its wholly glabrous leaves. It is 

 confined to the Cape Peninsula, where it was first detected near 

 Rondebosch by Burchell and latterly by Wolley Dod on the Lower
