CLETHRA, PYROLA, etc. The early view that the anthers of 

 Pyrolece. are in normal position in tiie bud (in other words, that they 

 are extrorse and the foramina basal), to which I reverted in the later 

 editions of the Manual of Bot. N. U. States, upon some observations by 

 the late Prof. H. J. Clark, must be adhered to. Baillon, indeed (in 

 Adansonia, i. 194), states the contrary with much particularity, appar- 

 ently from direct ol)6ervation : " Cliaque loge se termine en un tube k 

 pore de dehiscence apical. L'antliere est introrse quand le pore est 

 en haut.; elle est, par consequent, extrorse quand le pore regarde en 

 bas. Le filet est dans son jeune Tige rectiligne et dresse. Plus tard il 

 s'alonge beaucoup et s'inflecliit en se moulant sur la convexite de 

 I'anthere. Lors de I'epanouissement complet, il se redresse une seconde 

 fois en totalite." I can affirm, on the contrary, that the anthers are 

 developed from the first in this extrorse position, and undergo no in- 

 version in the bud ; indeed, the anther is well formed and the basal 

 horns i)lainly recognizable before the filament has an appreciable length, 

 at least such as would allow the former to execute the supposed 

 " mouvement de bascule." 



Clethra agrees with the Pyrolece in having primarily extrorse 

 anthers, as well as in the simple pollen and completely polypetalous 

 corolla. These characters are fully equal in value to those upon which 

 De Candolle and others break up the original Ericaceoi into separate 

 orders, and, if apprehended by Bentham and Hooker, might have led 

 them to give ordinal rank to the /*?/rofe«, appending Clethra, which they
