flower in autumn, they are apetalous. The species in question (H. glo- 
meratum), he says, had, in his garden, its shoots killed back a good way 
in winter, so that it did not flower till the autumn, and was, therefore, ape- 
talous, like fig. 69. Had the plant been protected during the winter, it 
would, most probably, he says, have produced plenty of perfect flowers in 
spring, as is the case with H. polygalefolium, H. brasiliénse, H. carolinianum, 
and the other American species.

Spec. Char., §c. Suffruticose. Branchlets simple,

Peduncles and calyxes hairy, canescent. Pedun- 
cles solitary, 1-flowered, inner sepals ovate, acumi- 
nated. (Don’s Mill., i. p.303.) A low shrub, found 
on the mountains of Brazil, introduced in 1823, 
and producing bright yellow flowers in June and 
July. It scarcely reaches 1 ft. in height, and might 
almost be considered as herbaceous. It is rather 
tender, and is best preserved when grown in pots, 
and taken into a frame or green-house during the 
winter. Plants of it were in the Botanic Garden 
at Chelsea, in 1826, where it flowered in the spring 
of that year, with petals, as in fig. 70., and in the 
autumn of the same year, without petals. 
Other Species belonging to this Division of Lechedides. 
H. polygalefolium Swt. Cist., t. 11., from Brazil, in 1823, with white flowers, 
and growing to the height of half a foot. H. dstylum Moc. and Sesse, a 
native of New Spain, has not been introduced ; and H. tripétalum and H. 
obcordatum Moc. and Sesse, both from Mexico, are also but little known 
to botanists, and not in cultivation in British gardens.
