palmata. It agrees fairly well with the meagre description given 
by De Candolle as Hedera cheirophylla. It has been suggested 
that it might be O. platanifolius, but this is said to have 7-lobed 
leaves and entire lobes, whilst our plant has the leaves 5-lobed 
and the lobes distinctly dentate. 
The following species belong to the Digitate. O. Thibauti 
is a small shrub with short petioles and narrow acuminate leaflets. 
O. xalapensis is a much larger shrub or small tree, with long 
petioles and broader, obovate, less acuminate leaflets. O. stellatus 
was received in 1903 from Mr. Geoffroy St. Hilaire, of Gros Pin, 
Hyéres. It seems to agree with the plant figured by Nicholson 
under fig. 772 as O. Epremesnilianus. 
All these species are dicecious, and none has borne fruit here. 
ORTHOSTEMON. 
O. Sellowianus is a hardy shrub recommended for its delicious 
fruit,* which so far has been but rarely produced. The flowers 
being very pretty, it is also of decorative value. It was first intro- 
duced by M. André from Uruguay to his garden, Villa Colombia, 
Golfe-Juan. 
OsTEOSPERMUM. 
O. moniliferum was raised from seeds given by M. Thuret, of 
Antibes, in February, 1869. It is a quick-growing shrub with 
soft and herbaceous branches, and pretty yellow flowers. The 
berry-like fruits are remarkable for a Composita. 
OTHONNA. 
O. crassifolia. Seeds were sown by Mr. Daniel Hanbury, 
November 21st, 1870. It is a small succulent herb with pretty 
yellow flowers, now nearly subspontaneous in the garden, doing 
well on the driest places. O. triplinervia is a pretty succulent 
shrub with yellow flowers. It was first introduced from Kew in 
July, 1868, and again by Mr. Daniel Hanbury in October, 1871. 
Both species came from Prof. MacOwan. 
OXALIS. 
O. cernua must now be pronounced a very troublesome weed, 
however reluctant one may be to apply this epithet to so beautiful 
a plant. It is recorded as a garden escape in 1806, and has since 
spread over all the Mediterranean region. Curiously enough, the 
plant is not known to produce seeds in this country, and can only 
be propagated by very small bulbs produced in quantities on the 
roots. The short-styled form only exists here, and one with 
double flowers is occasionally found. The plant is so perfectly 
acclimatized that it has adapted its flowering season to its new 
* This fruit is known as ‘‘ Araca do Brazil,” ‘‘ Arasa do Rio Grande,’’ and 
‘* Goyabo del Pays.’ It is about the size of an egg.—A good account has been 
recently published by Mr. F. W. Popenoe, ‘‘ Feijoa Sellowiana: Its History, 
Culture, and Varieties,” in Pomona College Journ. of Economic Botany, ii., 
February, 1912.
