322 NATURAL HISTORY OF PLANTS. 



few-flowered or reduced even to 1-8 flowers. Divided^ into more or 

 less unequal foliaceous lobes in Sommera, the calyx is spathelike and 

 opens unequally in Hippotis proper, whilst in Tammsia it represents 

 a large campanulate and veined envelope which divides into unequal 

 lobes. In all these plants the corolla is valvate, 4-6-lobed; the 

 ovary has two multiovulate cells, often incomplete, and the fleshy 

 fruit, surmounted by the persistent calyx, encloses numerous small 

 angular seeds with fleshy albumen. 



Fentagonia is also American and has flowers in axillary corymbiform 

 cymes, sessile or shortly pedunculate and pedicellate. The corolla, 

 tubular or funnel-shaped, is divided into five or six thick and valvate 

 lobes. The stamens are inserted near the base of the tube and often 

 have unequal filaments, recurved at the summit. The ovary has two 

 multiovulate cells and the fruit is fleshy. The flowers are, in fact, 

 nearly those of certain Genipas of the same regions, but with a valvate 

 corolla not contorted. They are shrubs, one volubile, with large 

 stipules and broad leaves which may be pinnatifid and not 'unlike 

 those of Artocarpus incisa. 



Ordinarily referred to quite a difl'erent group (Hameliece), Goiildia 

 is distinguished by its valvate corolla, the lobes of which are thick, 

 triangular on transverse section, in number four or five, and much 

 resembhng that of some Uragogas. The fruit is fleshy and opens 

 sometimes at the summit. The ovarian cells are multiovulate ; in 

 other respects the floral characters are those of Uragoga. The leaves 

 are opposite, and the flowers are either axillary or oftener in simple 

 few-flowered or branched and many-flowered cymes. They are shrubs 

 of the Sandwich isles. 



Mgrioneuron, shrubs of Asia and tropical Oceania, approaching 

 several of the preceding genera by their inflorescences in compound, 

 capituliform and terminal or axillary giomerules, has nearly the 

 flowers of Mussaenda, pentamerous, the calycinal divisions elongated 

 to a point, valvate corolla and two pluriovulate ovarian cells. The 

 fruit is fleshy or membranous and sometimes opens slowly or incom- 

 pletely. In this respect these plants approach the Oldenlamliem. 

 Payera consjncua, of Madagascar, appears to us near the preceding. 

 The two cells of its inferior ovary enclose each a multiovulate 

 placenta nearly sessile. The style is long and slender with two 

 branches. The corolla is five-lobed, valvate, surrounded by five 

 large foliaceous and persistent calycinal lobes. The fruit has a thin
