SAXIFBAGAGE2E. 347 



by a style, deeply divided into four linear lobes, which however long 

 remain sticking together into an apparently single column. They 

 are stigmatiferous at the apex. There are four cells superposed to the 

 petals, each with an axile placenta bearing a variable number of de- 

 scending ovules. The fruit is a partly superior septicidal capsule, con- 

 taining descending seeds like those of Philadelphia, with the embryo 

 surrounded by lieshy albumen. The only known species 1 of this 

 genus is a shrub from Texas and New Mexico, with opposite leaves 

 and terminal flowers, solitary or few together. 



Jamesia americana? is also a closely allied plant with pentamerous 

 diplostemonous flowers. Its ovary is in great part superior, J -celled, 

 with three or five oppositipetalous stylar branches, and as many 

 alternating multiovulate placentas, T-shaped in transverse section. 

 The fruit is a capsule, with the calyx persisting at its base ; it 

 opens at the apex between the styles to free the numerous albu- 

 minous seeds. This plant is a shrub from the Rocky Moun- 

 tains, with opposite exstipulate leaves, and flowers in ramified terminal 

 racemes. 



Near these, botanists have placed Carpenteria califoruica, 3 a shrub 

 with opposite leaves, and few terminal cymose 5-7-merous flowers. 

 The receptacle is shallow, the calyx valvate, the corolla twisted, the 

 indefinite stamens perigynous. The ovary, to a great extent superior, 

 has from five to seven cells, into the ventral angle of which project 

 two large placentary lobes covered with the numerous small ovules. 

 It becomes a loculicidal capsule with albuminous seeds, like those of 

 the preceding genera. 



Whipplea modesta* a low Calif ornian undershrub, has small flowers 

 with a concave receptacle lodging part of the ovary, and bearing on 

 its rim from four to six sepals, as many petals, and twice as many 

 free stamens with didymous anthers, those opposite to the petals 

 being the smaller. The partly inferior ovary has four or five cells, 

 each containing a descending ovule attached close to the apex of the
