PASSIFLORA 109 



the mildest parts of Great Britain. Nearly all have large 

 flowers, but they are not easy of cultivation. M. Clematis 

 has red flowers ; M. decurrens is deep orange, 4-5 in. across ; 

 M. ilicifolia has flowers varying from white to rose, leaves 

 holly-like; should be grown under glass. The leaves of 

 some of the species terminate in tendrils. It is said that 

 many gardeners have killed M. decurrens by planting it in 

 hot and dry positions, whereas it requires moisture, cool- 

 ness, air, sunshine, and a few slender sticks to ramble 

 over. It grows well in South Cornwall. 



ODONTADENIA 



O. speciosa (Dipladenia Harrisit), the only cultivated 

 species, has large racemes of trumpet-shaped yellow 

 and orange flowers, delicately scented. The lanceolate 

 leaves are a foot long, smooth, and dark green. Planted 

 in a border in a tropical house is the best treatment ; if 

 grown in pots, plenty of root room and thorough drainage 

 are necessary. Propagation by cuttings of the young 

 shoots. 



OXERA 



A genus of climbing shrubs, natives of New Caledonia. 

 O. pulchella, the only cultivated species, is a strong grower, 

 with the habit of Clerodendron Thomsonce, and large 

 panicles of tubular, yellowish-white flowers, freely pro- 

 duced in winter. It requires a sunny position in a stove, 

 and rich, loamy soil. Propagated by cuttings.
