THE FLORIST AND 



posed of six or seven pairs of leaflets, scarcely petiolated, with & 

 terminal odd one on a rather long petiole; leaflets lanceolate acu- 

 minate, the lower ones more convex on the upper than the lower 

 edge, dentate on the upper edge from about one third the distance 

 from the base ; the lower edge is always most entire, except a few 

 small teeth near the point. The terminal leaflet is dentate on both 

 edges, but not near the' base ; nut somewhat ovate, pointed at the 

 upper extremity, less so at the lower, flattened, somewhat rough, and 

 slightly angled ; 14 inches long, one inch broad. 



Differs from H. olivseformis or common Pacane nut, in being a 

 much smaller tree, seldom being more than 10 or 12 feet high, 

 whilst the other frequently reaches to 80 or 90 feet ; in the smaller 

 size of the leaves, which rarely exceed 14 inches in length, the 

 leaflets being 4 or 5 inches long, whilst the H. olivaeformis has the 

 leaves from 19 to 20 inches long and the leaflets 7 inches; but 

 most peculiarly in the shape of the nut ; this, in our species, is 

 ovate, flattened, although protuberant o& the sides and rough ; i& 

 the other very smooth, cylindrical, pointed at each end. The 

 leaves of the H. olivaeformis are fully formed before this species* 

 shows the least si<m of foliation.
