Ord. XIX. SAXIFRAGES. Juss. 



1. Broussaisia arguta. Gaud, in Freyc. Voy. p. 479. t. 69. De Cand. Prodr. v. 4. p. 17. 



This is a small-sized tree, the branches being soft and spongy, and filled with pith. The leaves are 

 opposite; the petioles are short, and furnished with a remarkable dilatation or appendage at'their back, where 

 they spring from the branch. This dilatation is not connected with the branch by any vessels; but when 

 the leaf falls off, which it does very readily, it leaves a heart-shaped scar, so large as almost to meet that at 

 the base of the opposite leaf. De Candolle places this in the Saxifrages, close to Hydrangea and Deutzia, 

 to the former of which genera it is allied in habit : but the style, which is very short, has a truncate and 

 simple, although indistinctly lobed stigma; and the ovarium has five cells, and is perfectly free from the calyx.

Ord. XXI. ARALIACES. Juss. 



1. Panax? Guadichaudi ; caule arboreo glabro inermi, foliis digitatis petiolatis superiori- 

 bus oppositis, foliolis quinque longe petiolulatis ovato-ellipticis obtusis remote et argute 

 serratis coriaceis, pedunculis terminalibus umbellas paniculatim dispositas gerentibus, pedi- 

 cellis brevissimis, stylis 3, fructibus globoso-trigonis 3-spermis. De Cand. Prodr. v. 4. p. 

 253. — Aralia trigyna. Gaud, in Freyc. Voy. p. 474. t. 98. 



The panicles are much shorter than the leaves. Two of the leaflets are often abortive, so that the leaves 

 appear ternate. The three styles render it dubious whether to place this species in Aralia or Panax. 

 It was first discovered long ago by Mr. Menzies, from whom we have a specimen in our herbarium. 



2. Panax? ovatum ; caule arboreo glabro inermi, foliis petiolatis superioribus oppositis, 

 foliolis tribus longe petiolulatis ovatis integerrimis coriaceis. 



The whole plant, as far as we can judge from the individual before us, is quite glabrous. The petioles are 

 opposite, about three or four inches long : the partial ones about an inch or an inch and a half. The leaflets are 

 broadly ovate, not acuminated, but slightly obtuse; the upper surface is glossy; the margin perfectly entire. 

 There is neither flower nor fruit on the only specimen in the Collection, which was found in Oneeheow ; but 

 it is very nearly allied to the last species. 



3. Panax? platyphyllum ; caule arboreo glabro inermi, foliis petiolatis superioribus oppo- 

 sitis, foliolis tribus longe petiolulatis transversim oblongis longitudine duplo latioribus apice 

 subiter apiculatis coriaceis integerrimis, pedunculis terminalibus umbellas paniculatim dis- 

 positas gerentibus. 



Caulis arboreus, inermis, glaber ut tota planta. Folia, saltern superiora, opposita: petiolus 4 uncias et 

 petioli partiales duas longi : foliola circumscriptione valde singulari, tres fere uncias longa et tautummodo 

 sesquiunciam lata, vix emarginata at breve apiculata, venis plurimis parallelis divergentibus. Panicula
