soiitaria, transvers. caeter. longitud., sub coriacea, rubro- 

 sanguinea. Pistilla, uti judicare licet ex exemplaribus 

 maturatis, solitaria. 



Capsula erecta vel transversa, basi c. internae basi cincta, 

 ramis longitudinalibus irregularibus pertusa apice clausa de- 

 mum irregulariter circumscissa, cellulae oblongo quadratae 

 quadrataeve fuscescentes efibrosse, sporula brunnescentia, tu-

1. Portion of a plant magnified. 



2. Portion of upper surface. 



3. Stoma, and portion of the green parenchyma, viewed 

 from within. 



4. Peduncle and involucra, of the valves. 



5. Peduncle terminated by one capsule and its involucre. 



6. Section of no. 4, half of each valve remaining, 



7. Apex of capsule, circumscissed. 



8. Portion of tissue of do. 



10. Sporula viewed on different faces. 



11. And 9, Elaters. 



12. Transverse section of peduncle.
