require very little water. The best way to flower them is to expo&e them to the air all the summer, which 
makes them get plump and nhrows them, into flower-bud. Most of the species are fine flowers. Cuttings, after 
they are taken off, should be left to dry a few weeks till they are shrivelled, tlien potted, and they v/iil root 
immediately. {Bot Cult. 31.) 
1112. Rhipsalls. From jj^-vl/; a willow branch, in allusion to the flexible decumbent branches of the genu.<!. 
Curious, branched, jointed, leafless, prostrate plants. Culture as in Cactus. 
1113. Bartonia. Named by Pursh, in honor of Dr. B. S. Barton of Philadelphia^ an American botanist. 
Beautiful plants, with alternate pinnatifid rough glaucous leaves, and large white flowers, which open during 
the night, and spread a most agreeable odor. Very rare, if they yet exist, in collections. 
1114. Philadelphus. A name used by Athenseus for a tree which is now unknown. Bauhin applied it to this 
genus. The species are free flowerers, well adapted for the shrubbery. The native country of P. coronarius 
is not known ; it is generally referred to the south of Europe, but it has only been found twice in Italy, and 
then in situations where it might have been planted. The flowers have the appearance and odor of these 
of the orange, but the odor in near contact is much more powerful. Seeds are seldom produced in this 
country. The leaves taste like fresh cucumbers. P. grandiflorus is a very shewy plant. All the species grow 
freely in common soil, and are increased by layers. 
1115. Leptospermum. From Xicrrcx;, slender, and crcn^/x-/!, seed, in allusion the extreme tenuity of the seeds. 
Pretty New Holland plants. L. scoparium grows commonly in dry places near the slioi-es in New Zealand, 
and the underwood in Adventure Bay, Van Dieman's Land, chiefly consists of this shrub. The leaves were 
used by Captain Cook's ships' crews as tea, whence they named it the tea plant. The leaves have a very 
agreeable bitter flavor, with a pleasant smell, when fresh; but lose something of both, when dry. If th<; 
infusion was made strong, it proved emetic to some, in the same manner as green tea. It was also used with 
spruce leaves, in equal quantity, to correct their astringency in brewing beer from them ; and they rendered 
the beer exceedingly palatable. 
Young cuttings of all the species will root readily in sand, under a bell-glass : the species may also be raised 
from seeds ; but plaiits from cuttings are best, as they flower voung, and the seedlings do not "flower til! they 
attain a considerable size. {Bot. Cult. 214.) 
1116. Fabricia. Dedicated by Gtertner to John Christian Fabricius, the famous Entomologist. The species 
and Miscellaneous Particulars.
