so low ; four-celled, polysporous, placentæ from the inner 
angles. Style erect, as long as the stamina. Berry ovate, 
four-celled, many-seeded. 
Oss. Besides being tetrandrous, this species is remarkable for 
7 the unusual mode of attachment of the anthers to the fila- 
ments, of which a partial example is afforded in the preced- 
ing. There is a strong resemblance between the two in 
habit as well as in this particular. Here we have the ovary 
completely adnate to the calyx, while in the preceding the 
anthers reach lower down, and are therefore lodged in cells 
betwixt them; but the two species are too nearly related in 
all other respects to admit of being separated on this ac- 
count.

base, very acuminate, four inches long, smooth, dotted with 
minute tubercles above, three-nerved, with a less distinct 
marginal pair, the transverse veins conspicuous.  Petioles

Bracts linear. Calyx ovate, smooth ; limb absolutely four- 
lobed, persistent. Corolla blueish-white, four-petalled. Sta-
