Fir;. 14. Drawings, about half the natural size, of the leaves of the common 

 quinquefoliate Virginian creeper (i and 2), of the adherent " Ampelopsis 

 Veitchii" (3 and 4), and of the poison- vine, Rhus toxicodendron (5 and 

 6). From specimens in the Botanical Department of the Natural History 

 Museum. Note especially the greater length of the stalk of the central 

 leaflet in the poison-vine. Note also that the common Virginian creeper 

 has sometimes only three leaflets (2) instead of five, and that " Veitchii" 

 has either three leaflets, as in 3, or has the leaflets united into one three- 

 pointed leaf, as in 4.
