578. BEGONIA MONOPTERA. Link and Otto. A tuberous 
greenhouse perennial. Flowers pure white. Native of Mexico. 
Belongs to Begoniads. - (Fig. 282. 
This very pretty species seems to be unknown in England. It was 
found in Mexico by Deppe, and by him the tubers were sent in 1826 to 
the Botanical Garden, Berlin, where it flowered. It is described as having 
a simple taper reddish s growing two feet high and more, and covered 
with extremely delicate vesicles. e leaves have a long hich i 
flat towards the top ; its blade wedge unequal-sided, three inches

manner, bright green on the upper side, deep red on the under, The 
flowers grow in a terminal thyrse, with ES pito flower-stalks. 
Among the flowers are some bulbs. The ovary has one lanceolate wing, 
white, with the wigs rolled back. The flowers appear in July and August. 
It is propagated by tubers, seeds, and the small tuber-like bodies among the 
owers, The latter should be placed in dry sand as soon as the stems are 
dead.— Zink and Otto, Icones.

stems are more an , and the flower-scape is less densely laden with 
bloom ; the flowers, too, are altogether different.” The flowers, however, 
racters, there is no difficulty in distinguishing this species. In the s = 
of the Royal Gardens of Kew it flowers in May. Our plant has Mant club-shaped stems, jointed and deeply suleated, 
growing in elusters ; at the base they swell out into a kind of pseudobulb, scarcely so large as a hazel-nut. The young 
stems bear from twò to four spreading, ovate, coriaceous or fleshy leaves at the top, acute, striated ; the old stems throw 
out pendulous racemes from near. the aunit which exceed the stems in length. Flowers numerous, but rather lax. 
Bracteas ovate, concave. Sepals very patent, broad, ovate, obtuse, pale straw-colour, delicately tinged with rose. 
Petals of the same colour and form, but larger, spreading, Lip moderately large, pale straw-colour, the whole dise
