7S r.KKAXHIM FAMILY. 



3. FL'KRKKA. Sepal*, small petals, stigmas, and lobes of the ovary 3 ; and 



stamens 6 : otherwise like Limnanthes. 



4. GK KAN I I'M. Sepals ami petals 5, the Conner imbricated, the latter commonly 



convolute in the bud. Glands on the receptacle 5, alternate with the petals. 

 Stamens 10, monadclphous at the base, the alternate filaments shorter, but 

 u-uallv bearing an -hers. Style 5-cleft. Ovary 5-celled, 5-lobed, the lobes 

 separating when ripe into 5 two-ovuled but one-seeded carpels or little pods, 

 which remain hanging by their long naked recurving styles as these split off, 

 from below upwa d<, from a long central beak or axis. (Lessons, p. 125, 

 fig. 277, 278.) Leave* with stipules Herbage scented. 



6 ERODIUM. Stamens witli anthers only 5. Styles when they split off from 

 the beak bearded inside, often twisting spirally : otherwise as Geranium. 



* 2. Flowers somewhat irreyulir, Geranium-tike. Shrubhy or fleshy-stemmed. 

 i PELARGONIUM. Sepals and petals 5 ; the base of one sepal extends down- 

 ward on one side the pedicel forming a narrow tube or adherent spur, and 

 the two petals on that side of the flower differ from the rest more or less in 

 size or shape. Stamens witli anthers fewer than 10, commonly 7. Pistil, &c. 

 as in Geranium. Herbage scented. Leaves with stipules. 



$ 3. Flowtrs very irregular, sjturrtd, also unsymtnttrical. Tender herbs. 



7- TROl'jEOLUM. Sepals 5, united at the base, and in the upper side of the 

 flower extended into a long descending spur. Petals 5, or sometimes fewer, 

 usually with claws : the two upper more or less different from the others 

 JJnd inserted at the mouth of the spur. Stamens 8, unequil or dissimilar ; 

 filaments usually turned downwards and curving. Ovary of 3 lobes sur- 

 rounding the base of a single stvle, in fruit becoming 3 thick and fleshy 

 closed separate carpels, each containing a single large seed. Herbs, climbing 

 by their long leafsta'ks ; the watery juice with the pungent odor and taste 

 of Cress. Leaves alternate : stipules none or minute. Peduncles axillary, 

 one-flowered. 



8. IMPAT1ENS. Sepals and petals similarly colored, the parts belonging to each 

 not readily distinguished. There are 3 sm.ill outer pieces plainly sepals, on 

 one side of the flower : then, on the other side, a large hanging sac contracted 

 at the bottom into a spur or little tail; within are two small unequally 2-lobed 

 petals, one each side of the sac. Stamens 5, short, conniving or lightly 

 cohering around and covering the 5-celled ovary, which in fruit becomes a 

 several-seeded pod : this bursts elastically, flying in pieces at the touch, 

 scattering the seeds, separating into 5 twisting valves and a thickish axi>. 

 Style none. Seeds rather large. Krect, branching, succulent-stemmed herbs, 

 with simple leaves and no stipules. 



1. OXALIS, WOOD-SORREL. (Nanu> from Greek words meaiiin- -S-OMJ-- 

 salt, from the oxnlntcs or " sal t-oi -sorrel " contained in the juice.)

 monly crimson underneath, only I'lon-': scapes short, 1 -flowered; petals 1^'
