Dr. Pfester, of Heidelberg, has studied Orchidee oak 
ing to their vegetative char acters, and thus has made an important 
advance. J. G. Beer, of ienna, in gta s criticising Lindley’s 
classification, proposes a division the order into six tribes 
founded sole ly 0 on modifications of the labe enn; but to the total 
neglect of all other characters structural or vegetative. In revi 
ing the Lindleyan system Mr. Bentham observes that tlie ‘inary 
division founded on the consistence of the pollen has not been 
replaced by any other equally good, although it is by no means 
ic olute. He admits that the distinctions founded upon the 
nd scarcely be mai i 
been applied to three different parts of the polling yeliais In 
the case of Vandea, Darwin, distinguishing it froma the caudicle, 
proposes to call it ** pedicel”; : " but as this word has already a special 
designation in some flowers, "Mr. Bentham thinks “ stipes’? a more 
appropriate term. The results of his detailed examination of all 
the genera proposed or established, of which he could procure 
specimens living or dry, checked by published daeeaiptings and 
illustrations, has head their distribution into five tribes and some 
twenty-seven subtribes, as tabulated below. Mr, Bentham thereafter 
enters into lengthened explanations of the several tribes, subtribes, 
and more remarkable genera in the order, in his usual critical and 
careful manner
