[The genera of Araliacew have been re-examined and arranged as follows in the 

 c Genera Plantarum' : 



TRIBE I. AUALIEJE. Petals more or less imbricate, attached by a broad base. Stilbocarpa, 

 Aralia, Pentapanax, &c. 



TRIBK II. MACKINLAYEJ:. Petals shortly clawed, involute, valvate. Mackinlaya. 



TRIBE III. PANACEA. Petals valvate. Stamens as many as the petals. Albumen not 

 ruminate. Horsfieldia, Panax, Acanthopanax, Fatsia, Didymopanax, Helwingia, Heryta, Sciado* 

 phyUum,) Heptapleurum, Dendropanax^ &c. 



TRIBE IV. HEDEREJ;. Petals valvate. Stamens as many as the petals. ' Albumen

Araliaccce approach Umbellifei'ttf Ampelufag, nnd Caprifoliacfis (gee these families). They are 

 Closely connected with Comete ; in Loth the petals are epigynous and isostemonous and valvate, the
