114 Dr, GoODENOUGH and Mr. Woodward'j Obfervations on 



membranacea tenerrima — Caulis breviflimus, teres, filiformis ramo- 

 fus, ramis membrana tenuiftima utrinque alatis — Folia membranacea 

 plann, integerrima, figura. magnopere variant; plerumque lineari- 

 lanceolata funt, faepe autem linearia, lanceolata ; nonnunquam ad 

 formam ovalem accedentia inveniuntur. Folia adultiorum per- 

 currit coda craffiufcula, ex qua oriuntur folia plurima prolifera, et 

 ex his iterum iterumque alia, poflrema femper lanceolata — Frudiifi- 

 cat'io, tubercula parva ruberrima, in ipsa. cofll fita — Occurrunt 

 etiam fpecimina in quibus tubercula nulla in cofhis adfunt, fed gra~ 

 nula minutiffima rubra in membrana ad utrumque coflas latus 

 feriatim difpofita obfervantur. 



This elegant fpecies cannot be confounded with any other in 

 this divifion, or indeed in the whole genus ; the perfectly entire 

 leaves, repeatedly proliferous, and always from the midrib, with 

 the total abfence of lateral nerves, fufficiently diftinguifhing it. 



The (talk, and the fhort branches, from which the leaves arife, 

 are winged with a thin membrane in the younger plants ; and from 

 this circumftance, in a former volume of thefe Tranfactions, it was 

 propofed to place it in the order Alati: but in the older fpecimens 

 this membrane is frequently wanting ; and the leaves being as com- 

 pletely diftintt as mfanguineus, or any other fpecies in this divifion, 

 it has been thought mod ccnfonant to the general arrangement 

 to place it here. 



The twofold appearance of the fructification requires particular 

 observation. In fome plants confpicuous tubercles of a deep red 

 colour, and evidently filled with feeds, are to be obferved on the* 

 midrib — in others, only very minute red dots, difpofed in parallel 

 lines, upon the membrane on each fide of the midrib ; and thefe 

 different appearances have never been obferved on the fame plant.
