Tii'g°iiiiaii Creeper. American Ivy. 



Calyx very short, turbinate, truncate, obscurely five-cre- 

 nate, fleshy. Petals 5, cucuUate, thick and fleshy, hypogy- 

 nous, valvate in aestivation, induplicate at the apex, separating 

 from the apex to the base in anthesis, spreading, deciduous. 

 Stamens 5, opposite the petals and shorter than they, hy- 

 pogynous, deciduous : filaments subulate : anthers oblong, 

 fixed near the base, introrse, two-celled, the cells opening 

 longitudinally. Disk entirely wanting ! Ovarv ovate, ses- 

 sile on a very short hypogynous torus into which the petals 

 and stamens are inserted, two-celled : style none : stigma 

 depressed-capitate. Ovules 2 in each cell, collateral, erect 

 from the base, anatropous, the raphe next the axis. 



Fruit a spherical two-celled berry ; the cells two-seeded 

 or by abortion one-seeded. Seeds obovate, with a membra- 

 naceous testa covering a thicker bony integument, which is 

 strongly induplicate longitudinally on each side of the raphe, 

 and a little incurved on the opposite side ; the cartilaginous- 

 fleshy albumen thus appearing deeply three-lobed on the 

 transverse section. Embryo very small, next the liilum in 

 the base of the albumen : cotyledons ovate, flat, shorter 

 than the inferior radicle. 



Shrubby vine extensively climbing by tendrils; the 

 branches tumid and readily separable at the nodes. Leaves 

 alternate, with membranaceous caducous stipules, digitately
