either side with a rather thin wing (Z) and G), which in its 

 upper part may be erect or curved slightly inwards around 

 the anthers and stigma, while in its lower part the edge is 

 revolute (G) as in Pedicularis^ but the revolute portion ("die 

 Rolle") is quite smooth here. As both lips are erect and 

 close tightly, there is, between them, a very narrow entrance 

 to the flower, through which, on the one hånd, only very 

 small flies and other small insects can creep in, and on the 

 other hånd, only butterflies and bees with long proboscides 

 can gain entrance into the flower. The anthers of the long 

 stamens open before those of the short ones (//), and the 

 anthers of the latter always remain enclosed, while those of 

 the long stamens protrude more or less. Here also the style 

 appears to vary in length; in some inflorescenses I found it 

 protruding far, even in quite young flowers — sometimes 

 so young that they must rather be called buds (E); and as 

 the stigma here also appears to be developed early, these 

 flowers must be called longistylous^ — protogynous. In other 

 flowers I found the stigma to protrude less, but nevertheless 

 to be higher than the anthers, while in others again the 

 long stamens were so long that their anthers were in con- 

 tact with the stigma, or even protruded above the latter 

 (//)." (The author then goes on to say, that among flowers 

 from the same. inflorescence there may be some difference 

 as regards the relative length of the style, the stamens and 

 the corolla which apparently cannot be referred to differ- 

 ence in age); "in flowers such ås A, B and E (from the 

 same inflorescence) self-pollination will be able to take place 

 only with difficulty, the stigma being throughout higher than 

 the anthers and the flower standing erect, hidden behind the 

 large bracts provided with marginal lobes. Nor will self- 

 pollination be easy in a flower like G, but in flowers like
