118 THE FLORA OF THE AMBOY CLAYS. 
ARALIA POLYMORPHA Newb. n. sp. 
Pl. XXXIX, figs. 1-5. 
Leaves extremely variable in form, three- to five-lobed, frequently 
unsymmetrical, the middle and larger lobe turned to one side, margins 
entire; nervation delicate, often invisible; lobes obtuse; petiole short or 
wanting. 
By reference to the figures now given it will be seen that this is a 
protean species, fig. 2 being quite symmetrical, having the outline of so 
many Aralias; that is, primarily three-lobed, but with a subordinate basal 
lobe on either side. Figs. 1 and 3 represent the distorted form to which 
allusion has been made in the description. Figs. 4 and 5 represent small 
and abnormal forms which may or may not represent this species. 
Locality: Woodbridge. 
ARALIA ROTUNDILOBA Newb. n. sp. 
Pl. XXVIIL, fig. 5; Pl. XXXVI, fig. 9. 
Leaves five-lobed, 10" wide by 7 or 8 high; lobes all rounded and 
comparatively short; margins entire; nervation delicate, camptodrome. 
Only two specimens of the leaf of this plant have been obtained. The 
most striking peculiarity is the rounded outline of each of the lobes. I 
have seen some specimens of Liquidambar integrifolium Lesq. in which the 
lobes are obtuse and somewhat rounded, giving the leaf very much the 
aspect of those before us. More material will be necessary, however, before 
the identity of the two forms can be asserted. 
Locality: Woodbridge. 
CHONDROPHYLLUM OBOvVATUM Newb. n. sp. 
Pl. XLII, figs. 26, 27. 
Leaves obovate to orbicular, 15™" to 25™ in length by 10™ to 20™ 
wide, margins entire, base more or less wedge-shaped, summit rounded 
and sometimes emarginate; nervation conspicuous and yet delicate, consist- 
ing of a midrib which vanishes near the summit of the leaf and gives off 
branches that unite to form festoons relatively remote from the margins,
