Miers I.e. Cervantcslam et lodlnani a Scmialaveis ad Styracaccas transfert, lobis squjimiformibus 

 disci pro pet^ilis perperam descriptis. Haj squamse, cum margine disci contiuuae, omnino similes sunt 

 iis Santali et Comandri, dum stamina certe extra discum affixa sunt etsi disco arete contigua, ut in 

 omnibus generibus subtribus Osyridcarum. Ovarium in alabastro liberum apparet omnino ut in 

 Sanfalo. Squamellje, in facie interiore segmentorum perianthii fructiferi a Miersio descript?e, sunt 

 vestigia persistentia filaraentorum post antheras delapsas. C?eterum Cervanfesia et lodina ab 

 omnibus affinibus diiferunt exocarpio (perianthii tubo) insigniter 5-sulcato facile in segmenta totidem 

 solvendo, etsi vix nisi basi sponte separatur.
