642 standley: north American species of genipa 



only from a single collection, and may be -merely a variant of the 

 common species. 



Genipa maxonii Standi., sp. nov. 



Large spreading tree, the wood pinkish, the branchlets glabrous, 

 with short internodes; stipules lance-oblong, about 3.5 cm. long, filiform- 

 attenuate, glabrous; petioles about 2 mm. long; leaf blades obovate or 

 rhombic-obovate, 34-44 cm. long, 13.5-25 cm. wide, narrowed from 

 below the middle to a rounded or subtruncate base, narrowed to the 

 apex and subabruptly obtuse-acuminate, chartaceous, bright green 

 above, reddish along the veins, sublustrous, glabrous, the costa and 

 lateral veins impressed, paler and reddish beneath, obscurely puberulent 

 when young, the venation prominent, the lateral veins slender, about 

 20 on each side, nearly straight, the secondary veins numerous, parallel, 

 distinct, the ultimate veinlets prominulous, reticulate, the margin plane; 

 fruit (probably immature) globose, 5.5 cm, in diameter, glabrous, the 

 pericarp about 4 mm. thick; seeds irregularly rhombic, 1.5-2.5 cm. 

 long, very thin, black, lustrous, the corklike flesh breaking up into large 

 fiat irregular sections, each containing a single seed. 



Type in the U. S. National Herbarium, no. 675223, collected in forest 

 along the Rfo Indio de Gatiin, Canal Zone, Panama, near sea-level, 

 February 17, 1911, by Wilham R. Maxon (no. 4848). 



The venation of the leaves is very different from that of G. americana, 

 and the leaves are narrowed to an obtuse base, rather than to a very 

 acute base, as in that species. The corklike flesh which envelops the 

 seeds appears quite unlike the flesh of young fruits of G. americana. 



The wood of Genipa maxonii has a beautiful pinkish tint. Mr. H. 

 Pittier forwarded from Panama a small box made of wood which appears 

 to belong to this tree, although it may have come from some allied 

 rubiaceous species. This wood is rather fine-grained, and probably 

 would take a handsome polish. It agrees in its pink coloration with 

 the branches of the type specimen of Genipa maxonii. When exposed 

 for some time to sunlight the wood loses its original color and assumes 

 a dirty-white appearance, but after being kept in a dark place the former 

 coloration is finally restored. 



Genipa williamsii Standi., sp. nov. 



Tree, 10 meters high, the trunk 12.5 cm. in diameter, the branchlets 

 reddish brown, glabrous, the internodes short; stipules broadly obovate, 

 1.8 cm. long, 1.2 cm. wide, cuneate at the base, rounded at the apex, 

 brownish, sparsely strigose outside; petioles stout, 1-2.5 cm. long, 

 glabrate; leaf blades obovate or oblong-obovate, 12.5-19 cm. long, 6- 

 9.5 cm. wide, acute or cuneate at the base, rounded at the apex, charta- 

 ceous, green above, sublustrous, glabrous, the venation plane or promin- 

 ulous, brownish beneath, strigose along the veins, the costa stout,
