the capsule several-seeded; seeds large, winged. There are 
three species described, from Mexico and Guayaquil. This 
genus was named after Cobo, a Spanish botanist. 
1. C. scandens (fig. 175).—This is the species commonly 
seen in gardens, having large purplish flowers. For out-door 
culture it is usually treated as an annual, and deserves to be 
more extensively employed for covering balconies and training 
around windows, on account of its rapid growth and pleasing 
foliage. It is anative of Mexico. There is a beautiful variety 
with variegated foliage. 
C. stipularis from Mexico and C. macrostéma from Guaya- 
quil have yellowish green flowers, the former being remarkable 
for its large stipules, and the latter for its long stamens, which 
exceed the corolla by one half. 
Cantia is a genus of handsome flowering shrubs from the 
mountains of Peru and Columbia. Leaves small, entire or 
pinnatifid, and alternate. Corolla funnel-shaped. Stamens 
more or less exserted. C. buwifolia and C. bicolor have 
splendid large orange and red pendulous flowers from the 
upper part of the branches; and C. pyrifolia has erect white 
and yellow flowers in terminal corymbs. These shrubs belong 
more properly to the greenhouse, though they will succeed in 
the open air near the sea in the south-western counties of 
England. 
Oxper LXXIII—HYDROPHYLLACES. 
(Including Hydroledcece.) 
Shrubs or herbs, often clothed with hispid hairs. Leaves 
lobed, alternate, or the lower ones opposite. Flowers in gyrate 
or unilateral racemes or spikes, rarely solitary and axillary. 
Calyx inferior, deeply 5-lobed, sometimes with appendages in 
the sinuses. Corolla regular, 5-lobed, campanulate, rotate or 
funnel-shaped. Stamens 5, inserted on the tube of the corolla 
and alternating with its lobes. Fruit a 1- or incompletely 2- 
celled 2-valved capsule; seeds few or many, attached to parietal 
placentas which sometimes meet in the centre. A small order 
with about sixteen genera and seventy-five species, chiefly 
American. The species of Hydrophgllum itself are almost 
unknown in gardens. They are North American herbaceous 
plants with large pinnately or palmately lobed leaves and
