and a second leaf and rect Leaves on slender petioles of 2—6‘, broadly 
ovate, orbicular or reniform, with a cuneate base, less than 1’ in diameter, 
rather thick with ssaniait subflabellate nerves, crenate, glabrate. Stipules 
deltoid, 2—3", with a few short teeth. Flowers dimorphous, the Jarger 
ones on peduncles of 2—4'/2‘, which bear a pair of short subulate bracts 
in the upper portion. Sepals 31/2, narrow lanceolate, the base produced 
into a short appendage. Petals twice as long, pale blue, not bearded, 
ited -spathulate, the lowest one slightly saccate. Anthers free, half as 
as the sepals, attached to the anterior face of a broad connective 
with anterior stigma. The shorter flowers (described by Gray) haye petals 
not exceeding the calyx, and stamens with distinct filaments nearly equalling 
the petals, while the style is thicker and hooked. Capsule acute, 5—6”, 
with 8—10 seeds to each placenta.
