422 HORTUS MORTOLENSIS 
PRIMULA. 
P. Alliont and P. marginata, natives of our Alps, live and 
flower for some time if brought into the garden, but lose much of 
their natural beauty. P. Palinwri, endemic in Southern Italy, 
where it grows on Cape Palinuri and Calate della Molpe, does 
quite well here. It was sent by Lady Ilchester. 
PROTEA MELLIFERA. 
A plant received from Messrs. Nabonnand, Golfe-Juan, in 1903, 
which has not yet flowered, is most likely this species. Seeds of 
P. abyssinica were sent in 1908 and 1911 by Prof. I. Baldrati, of 
Asmara. 
PRUNUS. 
Peaches, cherries, and plums succeed very well. Mr. Daniel 
Hanbury remarks in a letter from Antibes, December 7th, 1874: 
“Cherries thrive exceedingly well in this country, and produce 
excellent fruit and very early. But the trees must not be 
pruned ; pruning is apt to make them exude gum and is but of 
little use.” 
P. ursina, a native of the subalpine regions of the Lebanon, 
was grown from seeds collected there by Mr. Hartmann, in 1900. 
An unnamed species comes from Chitral Valley, where it was 
collected by Col. A. A. Barnet, in 1904. It is said to be a 
shrub or small tree, with numerous pure white flowers. With us 
it is deciduous, with glabrous virgate branches. For the seeds 
we are indebted to the late Sir Dietrich Brandis, who sent them in 
October, 1904. 
PsIDIUM. 
These shrubs ripen their fruit perfectly well here. P. Cattlei- 
anum was first brought here from Hyéres, in 1868, and again by 
Mr. Daniel Hanbury, in October, 1869, from England. 
PTERONIA. 
P. incana was introduced at La Mortola, in June, 1872, by 
Mr. Daniel Hanbury, who probably received the seeds from 
Prof. MacOwan. It is a shrub, 1:00-1:30 m. high, flowering from 
April to May, but not ripening seeds. It thrives on the hottest 
and driest banks of the garden, and has a very sweet scent. 
PUNICA. 
P. Granatum, the pomegranate. The large bush on the south 
front of the house existed already when Sir Thomas Hanbury 
bought the property in 1867. The variety nana, a much smaller 
tree or bush, was planted by Sir Thomas Hanbury, on November 
27th, 1868, on the north side of the house. It came from Messrs 
Veitch. 
Puya. 
P. chilensis was received from Mr. Dorrien-Smith, of Tresco 
Abbey, Scilly Islands, in May, 1901.
