6. Exogonium jalapoides (Griseb.) 



Ipomoea jalapoides Griseb. Cat. PI. Cub. 202. 1866. 



Stems woody below, densely pubescent : leaf-blades oblong- 

 lanceolate, entire, 3-5 cm. long, or 3-lobed at the base, the middle 

 lobe lanceolate, 4-5 cm. long, lateral lobes oblique, 2 cm. long or 

 less, densely appressed-pubescent above : peduncles 1-3 -flowered : 

 sepals oblong, obtuse, 7-9 mm. long, densely tomentose without : 

 corolla scarlet, the limb fully 4 cm. broad. 



Type locality : Cuba. 

 Distribution: Cuba. 



Specimens examined : C. Wright jop? (co-type in herb. 

 Columbia Univ.). 





7. Exogonium fuchsioides (Griseb.) 



Ipomoea fuchsioides Griseb. Cat. PI. Cub. 205. 1866. 



Stems finely appressed-pubescent : leaf-blades narrowly ovate- 

 Janceolate, acuminate, rounded or subcordate at the base, green 

 * n d appressed-pubescent above, pale and sericeous-pubescent 



eneath, 2-4 cm. long, sometimes 5-7 cm. long, obtuse, 3-4 cm. 

 wide and obtusely auricled at the base : pedicels and calyx gla- 

 brous : sepals unequal, 5-6 mm. long, obtuse, tinged with red : 

 corolla-tube 3 cm. long, 4-5 mm. in diameter; limb crimson, 



•5-2 cm. broad with 5 rounded lobes. 



Type locality: Cuba, " Bahia Honda". 



Distribution: Cuba. 



Specimens examined : C. Wright jops (in herb. Gray). The 

 j;°-type in the Gray Herbarium is mixed with the entire-leaved 

 0r m of E. microdactylum, which perhaps accounts for the mistaken 

 ^ntification of the latter in most herbaria as " Ipomoea fuchsioides ." 



Th 



: variety parvifolia Griseb. /. c. appears to be but a small 

 eaf -form, while the variety glabra belongs to the entire-leafed 

 v anety f E. microdactylum.
