Tkibe III. LIMN" ANTHER. FloNvers regular, slightly peiigynous, symmetrical. 

 Sepals valvate, persistent aud accrescent. Petals withering-persistent. Stamens 

 twice as many as the petals, all antheriferous. Glands of the receptacle evident. 

 Seeds exalbuminous. 



5. FLCERKEA. Flowers solitary at the ends of bractless axillary peduncles, 3-5(or rarely 

 6)-merous. Petals convolute or not overlapping when small. Carpels 1-ovuled, distinct, the 

 5-lobed style rising from the centre, in fruit becoming semi-drupaceous rugose-tuberculate 

 nutlets ; embryo straight, with flat cotyledons. 



Tribe IV. OXALIDE^E. Flowers regular, normally 5-merous, symmetrical, often 

 heterogone. Sepals imbricate, persistent, scarcely accrescent. Petals convolute, 

 often somewhat united toward the base. Stamens 10 ; filaments sometimes toothed 

 or with an additional set of auricles or sterile scales. Glands of the receptacle 

 greatly reduced or wanting, alternate with the sepals when present. Seeds al- 

 buminous. 



6. OXALIS. Flowers dichotomously cymose or seemingly umbellate. Stamens monadel- 

 plious in 2 sets of different length. Ovary somewhat 5-lol)ed, forming a loculicidal several- 

 seeded capsule tipped by the persistent distinct styles with capitate stigmas ; seed with a 

 longitudinally dehiscent arilloid outer coat, the firm inner integument usually sculptured ; 

 embryo straight, with plane cotyledons. 



Tribe V. BALSAMINEvE. Flowers irregular, hypogynous, usually unsymraetri- 

 cal from the suppression of 2 sepals. Sepals and petals imbricate, deciduous. 

 Stamens as many as the petals, all antheriferous. No glands of receptacle. Seeds 

 exalbuminous. 



7. IMPATIENS. Flowers several, on Iposely branched bracteate axillary peduncles. 

 Sepals 3, the posterior petaloid, saccate, and mostly slender-spurred. Petals 5, the lateral 

 pair on each side united. Stamens somewhat united by their appendaged filaments and 

 with more or less connate anthers. Style almost none ; ovary not deeply lobed, somewhat 

 fleshy. Valves of the cajisule at length breaking elastically from their septa and coiling ; 

 seeds with 4 longitudinal ridges ; embryo straight, with nearly plane cotyledons.
