CAPPARIDACE.E. 



Forchhammeria trifoliata Radlk. sp. nov. Tres Marias. 



Arbor glabra ; rami florigeri pallidi, lenticellosi, annulo ligni

 petiolata, trifoliolata ; foliola ex obovato cuneata, breviter acuti- 

 uscule acuminata vel obtusata, breviter petiolulata, margine 

 integerrimo subundulata, pallide viridia, fibris sclerenchymaticis 

 crebris percursa ; flores parviosepali, apetali, masc. in paniculam 

 amplam congesti, staminibus 12-15 disco insertis, fern, subrace- 

 mosi, germine intra staminodia pauca disco insidente ellipsoideo
