yet seen the labor of Hooker on the Gerardia. 



414. SCHWALBEA AMERICANA L. &C. I 



have several specimens of this fine and rare 

 plant, collected from New Jersey to Carolina ; 

 yet I never could meet it myself in 25 years of 

 botanical herborizations ! I mention this to show 

 again how easy it is for careless botanists to 

 overlook my new and rare plants or blend them 

 with others, if such plants escape my keen re- 

 searches. Well described by Elliot. The al- 

 ternate leaves and capsule with partition form- 

 ed by the valves, remove thisG. from the group 

 of Gerardias. 



MONOCOTYLES. 



Although 1 wish to be concise I have been 

 compelled to dwell upon some Genera impro- 

 perly known, and thus give again monographs 

 instead of mere insulated new species ; this 

 plan will be preferred by those who like to 

 compare the whole at once. Having till now 

 described Dicotyles only, I now mean to give 

 some new or rare Monocotyles in the remain- 

 der of this second part of my Fora ; the third 

 part whereof will be chiefly upon trees and 

 shrubs. 



415. UNISEMA Raf. 180S. Med. fl, 1830. 

 Fl. tell. 6. Beautiful distinct Genus of mine bas- 

 ed on the various species blended in Pontede- 

 ria cordata \ with a fruit quite peculiar simi- 

 lar to Grasses ! which our botanists have hesi- 

 tated to adopt, altho' they knew it was good, 

 having verified the fruit ! Perigone corolli- 

 form bilabiate 6fid, stamens 6 unequal filiform
