114 Dr. GooDENOUGH and Mr. Woodward'^ Obfervatiom on 



niembranaceateneniina — CW/> breviffimus, teres, filiformls ramo- 

 fus, ramis membrana tenuiffima utriiiquc alatis — Folia membranacea 

 plann, integerrima, figura magnopere variant; plerumque lineari- 

 lanceolata lunt, faspc autem linearia, lanceolata ; nonnunquam ad 

 formam ovalem accedcntia inveniuntur. Folia adultiorum per- 

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

 ex his iterum iterumque alia, poftrema femper lanceolata — Frudilfi- 

 catio, tubercula parva ruberrima, in ipsa cofta fita — Occurrunt 

 etiam fpecimina in quibus tubercula nulla in coflis adfunt, fed gra- 

 nula minutiflima rubra in membrana ad utrumque coftae latus 

 feriatim difpofita obfervaritur. 



This elegant fpecies cannot be confounded with any other in 

 this divifion, or indeed in the whole genus; the perfe6tly entire 

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

 the total abfence of lateral nerves, fufficiently diftinguifhing it. 



The ftalk, 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 Tranfaftions, it was 

 propofed to place it in the order j^lati: but in the older fpecimens 

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

 pletely diftinft as in fanguineus, or any other fpecies in this divifion, 

 it has been thought mofl ccnfonant to the general arrangement 

 to place it here. 



The twofold appearance of the frudlification requires particular 

 obfervation. 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.
