satisfying study the following treatment is proposed as the best I 



can yet arrive at. 



Calyx cleft nearly or quite to base: corolla-lobes lanceolate to 

 narrowly oblong, sharply acuminate or at least acute. 

 Plant yellowish-green, rarely purplish: inflorescence thyreoid 

 or a simple raceme : leaves and calyx-lobes firm, subulate 

 to linear-lanceolate, yellowish-green or at most purple- 

 tipped: flowers 2.5-5 mm. long: corolla-lobes mostly 

 creamy-white, lance-acuminate, 0.7-1.5 mm. broad: an- 

 thers mostly yellowish B. paniculata (typical) 



Plant purplish or fulvous: inflorescence a simple raceme, 

 rarely subpaniculate: leaves and calyx-lobes fleshy or 

 herbaceous; the latter deeper green to purple, lanceolate 

 to oblong: flowers 3.8-6 mm. long: corolla-lobes often 

 purple-tipped or watery-white, lance-oblong, 1.2-2 mm. 



broad: anthers mostly purple Var. intermedia. 



Calyx cleft (at least on one side) only two-thirds or three- 

 fourths to base; its lobes herbaceous, oblong to ovate: 

 corolla-lobes petaloid, oblong to narrowly ovate, blunt 

 or merely acutish, 1-2 mm. broad. 

 Racemes simple or dichotomous: pedicels clavate: 2 or 3 

 calyx-lobes distinct to base: corolla 3-5 mm. long, 



creamy-white: anthers mostly yellowish Vax . sabidunensis. 



Racemes mostly simple: pedicels filiform: calyx-tube 1-2 

 mm. long: corolla 4-7 mm. long, often purple-tinged: 

 anthers mostly purple Var. iodandra.

 peaty and wet cobbly shores. Yarmouth Co. : Jassy Lake, Lake

** B. paniculata, var. intermedia, n. var., plantis purpurascenti- 

 bus vel fulvescentibus; racemis simplicibus laxis, pedicellis elongatis; 

 foliis calycibusque herbaceis fulvo-viridibus vel purpurascentibus; 

 lobis calycis distinctis lanceolatis vel oblongis; floribus 3.S-6 mm. 

 longis; lobis corollae ochroleucis purpureo-tinctis vel translucentibus 

 lanceolato-oblongis 1.2-2 mm. latis; antheris purpurascentibus.
