brevioribus ; carina triloba, dorso crista callosa sed non 

 fimbriata ornata ; filamentis liberis longis ; ovario glabro ; 

 stylo elongate, apice incrassato et falcato ; capsula rotunda, 

 emarginata, anguste alata ; seminibns hirsutis ; arillodio 

 appendicibus tribus prsedito, quarum duae ventrales seminis 

 dimidium attingunt, dorsalis abbreviata est.

Per Europam centralem a Glallia australi ad Italiam se^^ten- 

 trionalem et Transylvaniam ; in Alpibus Helveticie et Ita- 

 lianis frequens ; in Britannia, Scandinavia, et Europa 

 austro-orientali non invenitur, nee, lit videtur, in penin- 

 sula Iberica nee Pyren^is. Localitas in ducatu Lucem- 

 burgensi est verisimiliter, ut cl. Ball censet, spuria-. 



The only Euroi)ean s^Decies of the section which, as mentioned 

 above, is enthely unrepresented in Asia and America, extending 

 only into Northern Africa. AVillkomm and Lange record one old 

 locahty in Ai-ragon, about which, however, there is, as they j)oint 

 out, considerable doubt.

Sectio IV. Brachytropis, Willk. (gen.), DC. 



Racemi axillares, multiilori ; sepala exteriora subinaequalia ; 

 alse persistentes, petaloidese ; petala lateralia e carina fere libera, 

 magna, convoluto-^quitantia, carina multo longiora ; carina 

 inclusa, ecristata ; ■ anthers 8, in filamentorum vaginam sub- 

 sessiles ; ovarium breviter stipitatum, stylo a^Dicem versus sub- 

 recurvato, stigmate insequaliter profunde bilobo ; capsula alata ; 

 semina parce albuminosa ; arillodium carnosum, galeatum, appen- 

 dicibus tribus brevissimis praeditum. 



One of the most distinct sections of the genus, and perfectly 

 monotypic. I do not, however, see sufficient reason for following 

 Willkomm and Lange in separating it altogether into a distinct 

 genus. In the more essential characters connected with the 

 stamens, pistil, and seeds, there is no great departure from the 

 ordinary type of Pobji/ala. The comparatively small included keel- 

 petal resembles nothing else in the genus, while the form of the 

 lateral petals is not unlike that in the South American genus Brede- 

 ineyera. The rigid nearly leafless habit reminds one of several 

 South American species of Pohjgala.
