3S0 NATURAL HISTORY OF PLANTS. 



one or two carpels, sometimes three, four, or five. The fruit is here 

 also a swollen follicle ; and the ovules, though less numerous than in 

 A\ thyrHiJlora, are still arranged in two vertical rows. They are at 

 first horizontal, but are afterwards displaced, so that as seeds some 

 become ascending with the micropyle extrorse, while others are 

 more or less descending.' Thus constituted, the genus Neillia in- 

 cludes four or five species from India, the east and nortlr of Asia, 

 and North America. These are bushy shrubs, with alternate 

 simple dentate or lobed leaves, possessing two large lateral, cadu- 

 cous stipules. Their flowers are in racemes or corymbs, which may 

 be simple or composed of alternate cymes. 



In Kerria^ the solitary terminal floral peduncle is swollen at the 

 apex, with only a shallow pit on top for the insertion of the gynie- 

 ceum ; while the low edges of this pit bear five persistent quin- 

 cuncially imbricated sepals, five alternating shortly-unguiculate 

 petals also imbricated' in the bud, and a large number of free sta- 

 mens' consisting of slender filaments, at first flexuous, bearing iii- 

 trorse two-celled anthers, dehiscing longitudinally. The cup is lined 

 with hairs and glandular tissue. The carpels are superposed to 

 the sepals when they are of the number ;' each consists of a free 

 ovary, and a slender style inserted at a variable height on the 

 internal angle, and truncate and stigmatiferous at the apex. Within 

 the ovary, about half-way up the ventral angle, is inserted a single 

 incompletely anatropous descending ovule,' whose micropyle looks 

 upwards and outwards, 'i'he fruit consists of a variable number of 

 achenes," whose seeds possess an exalbuminous embryo with its 

 radicle superior. Only one species of this genus is known. A'.
