Ipomoea Carletoni Holzinger n. sp. A much branched glabrous vine, trailing on 

 the ground ; leaves narrowly lanceolate, truncate to acute at base, mucronate at 

 apex, about 2 inclies long, exclusive of petiole (ono-half to an inch long) : flowers 

 2 to 2^ inches long, generally solitary but occasionally two or three at the end 

 of the common peduncle (1 to l^ inches long) ; pedicels little shorter than 

 peduncles: sepals oiic-half inch long, much imbricated, of unequal lengtb, apex 

 rounded or obtuse and generally mucroimlato, glabrous outside, minutely scab- 

 rous inside, the outer ones more decidedly so: stamens about |^ lengtii of cor- 

 olla; filaments densely hairy near their point of insertion on corolla: style 

 about i length of corolla; stignui rather discoid-peltate than capitate. Mature 

 fruit and root are desiderata to complete the characters. — Logan County, Okla., 

 and Cimarron River, near Guthrie. August. No. 472. 



This is near /. loiigifolia, but is more slender, and smaller iu all its parts. It 

 is not unlikely that it may turn out to bo a small variety of this species, but 

 until fruit and root are observed it is decided not to place it so.

 to show insertion of stamens ; all jiarta of natural size, except peduncles and pedicels, which
