genus. On application to M. Otto (from whom the plant in the Horticul-tural Society’s Garden was received) for further information, he could giveus none respecting its geography or history, further than that he had receivedthe cones (from one of which, very kindly sent by him to us, our fig. 2179. istaken) from Mexico, about 1827. P. Llaveana is, at present, one of themost rare species in England, though it might doubtless be propagated bycuttings, or herbaceous grafting on P. halepensis, which it most nearlyresembles.

App. i. Species of 3-leaved Pines which cannot with certainty bereferred to any of the preceding Sections, but of which there areliving Plants in England.

131. P. california'na Lois. The Californian Pine.

Identification. Loiseleur Deslongchamps, in the N. Du Ham., 5. p. 243.

Synonymcs. P. mcmtereyensis Godefroy; P. adtinca Bose, as quoted in Bon Jard., P. monthera-gensis in the Horticultural Society’s Garden j Pin de Monterey, Bon Jard., ed. 1837.

Spec. Char., &;c. Leaves in twos and threes. Cones much longer than theleaves. (Lois.) The following description of this species, written by Pro-fessor Thouin, is taken from the Nouveau Du Hamel :-—“ This tree growsin the neighbourhood of Monte-Rey, in California. One of its cones,gathered by Colladon, the gardener belonging to the expedition of LaPeyrouse, was sent to the Museum of Natural History in Paris in1787. The cone was in the form of that of P. Pinaster, but one thirdlarger in all its parts. Under each of the scales were found two seeds, ofthe size of those of P. Cembra, and of which the kernel was good to eat.These seeds, sown in the Jardin des Plantes, produced twelve plants;which, cultivated in the orangery, succeeded very well. Most of theseplants were afterwards sent to botanic gardens in the south of France.There still remains one specimen in the Jardin des Plantes, which hasstood for several years in the open ground ; where, without being vigorous,it remains in health.” Loiseleur Deslongchamps adds that this specimen,in 1812, was 7 ft. high, with leaves 3 in. long, very slender, and of adeep green. M. Vilmorin informs us that the tree in the nurseryof M. Godefroy, from which all the young plants sold by him have
