 gins, a little shorter than the globose capsule; petals free, retuse, blue, 

 3-4 times the length of the calyx; styles 5, capsule 5-celled, with bearded

 rigid, with scabrous margins; flowers panicled or corymbose; pedicels 



1 SPH^ERALCEA, St. Hil. Involucel 2-3 leaved, setaceous, often deciduous. Stigmas 

 capitate. Ovaries many, 15-20. Carpels 1-celled, 2-ovuled, the lower ovule ascend- 

 ing, the other pendulous, compressed, often truncate and pointed above, membra na- 

 ceous or coriaceous, 2-valved above, hardly separating from each other and from the 

 axis Radicle inferior, or in the upper seed centripetal-superior. Gr., Gen. ///., 2, p. 69. 



2 ABUTiLOisr, Tourn., Gaertu. Involucel none. Stigmas capitate. Ovules 3 in each 

 carpel, rarely 4-9, all or the lower spreading or resupinate-pendulous. Fruit of 5-mnny 

 carpels. Carpels, 1-celled, about 2-valved, scarcely separating from the axis. Radicle
