Calyx of five nearly distinct and equal herbaceous sepals, 

 quincuncialLy imbricated in aestivation, not produced or tubu- 

 lar at the base, persistent. Petals 5, hypogynous, alternate 

 with the sepals, equal, someAvhat unguiculate, convolute or 

 sometimes quincuncially imbricated in aestivation, caducous. 

 Hypogynous glands 5. alternate with the petals. Stamens 

 10, hypogynous, inserted in two series on the short recepta- 

 cle ; the five exterior opposite the petals, sterile (destitute of 

 anthers) and shorter than the five fertile, which are opposite 

 the sepals and the glands : filaments dilated below, mem- 

 branaceous, persistent, distinct or slightly monadelphous : an- 

 thers oblong or cordate, introrse, two-celled, the cells open- 

 ing longitudinally. Pistil, (fcc, as in Geranium. Ovules 

 two in each ovary, inserted one above the other on the mid- 

 dle of its inner angle, anatropous, pendulous, or the upper 

 resupinate-ascending. 



Fruit of five small coriaceous (and internally dehiscent 

 or often indehiscent) achenia-like carpels, awncd by the long 

 and indurated persistent styles ; which at maturity separate 

 elastically from the long and slender beak-like axis, com- 

 monly from the apex downwards, and are villous with strong 

 hairs along the inner face, the lower part twisting spirally.
