416 HORTUS MORTOLENSIS 
home. O. purpurata, with beautiful purple flowers, is spreading in 
several parts of the garden. 
OXERA. 
O. pulchella is a beautiful climber, but rather tender for the 
Riviera. It flowers in the garden of Villa Cava at Bordighera, 
whence we received it. 
PACHYPHYTUM. 
Differs scarcely from Echeveria. P. bracteoswm was procured 
by Mr. Daniel Hanbury from Mr. Thomas Cooper, Reigate, in 
July, 1868. 
PHONIA. 
P. peregrina is a native of our nearest mountains (Monte 
Grammondo and Mt. Mulacé), where it grows in the most rocky 
places (at about 1200 m.), and produces in May most beautiful 
flowers. Like all other species, with the exception of P. lutea, it 
does very well in the garden. 
PANDOREA. 
P. (Tecoma) australis is a very vigorous, tall and woody, free- 
flowering climber. Seeds were received from Villa Thuret, Antibes, 
in February, 1869. We grow two varieties of it, one correspond- 
ing exactly with Ventenat’s figure, with large flowers, and another 
with somewhat smaller pale yellow flowers. P. jasminoides is 
considerably less vigorous ; it was bought at Hyéres in December, 
1867. 
PAPHIOPEDILUM. 
Better known in gardens as Cypripedium. All the species 
enumerated do well in the open, in the shade of the pergola. 
PASSIFLORA. 
Some species thrive beautifully, and P. actima, P. cerulea, 
P. racemosa have been long established in the garden. P. Hahni 
and P. capsularis were received from Kew in 1905, and succeed 
perfectly. Many of them produce fruit more or less abundantly, 
but I have never seen P. actinia and P. racemosa do so. P. edulis 
produces its much appreciated fruit freely when planted in a warm 
position. 
PEIRESKIA.* 
Peireskias just manage to live in the open, but do not make much 
progress. Under glass they grow and flower in great profusion, 
especially P. acwleata, which occupies a large space in one of the 
greenhouses. In autumn it is literally covered with pretty little 
flowers, with a strong and rather disagreeable smell, but it rarely 
fruits. It was probably procured by Mr. Daniel Hanbury from 
Kew in July, 1868. P. brasiliensis and P. discolor were received 
in 1901 from Dr. Weber. Others were received in 1906 from Mr. 
* The genus was named in honour of Nicolas-Claude Fabri de Peiresc 
or Peiresk (1580-1637), one of the most learned men of his time. Peiresc, the 
feudal fief of the family, is a little village near Nice. See Dr. F. Mader in 
Monatsschrift fiir Kakteenkunde, 1910, p. 23, with figure.
