440 GENERAL REVIEW. 



related to Passiflora, and represented in our gardens by T. 

 mollissima, T. insignis, T. Van Volxemii, and others. All the 

 species are readily raised either from cuttings of the young 

 growth, layers, or seeds. Several cultivators have raised hybrids, 

 all more or less beautiful. The new T. Exoniensis, sent out 

 in 1873 by Messrs R. Veitch & Son of Exeter, was raised by Mr 

 John C. Bowring at Larkbeare, Exeter. It is a cross between 

 T. Van Volxemii, which was the seed-bearing parent, and T. 

 mollissima, the latter being the pollen-parent. It flowered and 

 was described in 1872 (see 'Gard. Chron.' 1872, p. 1653). 



Mr Anderson, of the Gardens, Sowerby House, Hull, to 

 whom we owe our first knowledge of the beautiful T. insignis, 

 has hybridised that species with T. Van Volxemii, the latter 

 being the pollen-parent. We subjoin Mr Anderson's remarks, 

 which are interesting as confirming the fact that Passifloras 

 often set better with foreign pollen than with their own : " T. 

 insignis never seeds with me unless it be artificially impreg- 

 nated, and then not freely with its own pollen, but more so 

 with that of Van Volxemii. Out of about forty plants which I 

 raised from two seed-pods, all, with one exception, have the 

 divided leaf of the male parent, while one seems in every 

 respect a true insignis" 



T. mollissima and T. Van Volxemii bear edible fruit, and 

 in this respect they might possibly be much improved by being 

 hybridised reciprocally with the edible-fruited Passion-flowers. 



THE MOCK-ORANGE FAMILY (Philadelphaceiz). 



A small group of deciduous shrubs found scattered through- 

 out Europe, North America, India, and Japan, and repre- 

 sented in our gardens by different species of Philadelphia and 

 Dentzia. They are nearly allied to Escallonia, an evergreen 

 genus readily propagated by cuttings, layers, or seed, just as 

 are the Syringas. All the species are beautiful flowering- 

 shrubs, which bear forcing with impunity ; and there is a wide 

 field for further experiments in hybridising and seminal varia- 

 tion and selection, by which these plants may be much im- 

 proved. 



Propagation is readily effected by means of cuttings, either 

 herbaceous or hard-wooded. The latter are made from No- 

 vember to March, in the following manner : The branches are 

 cut into lengths of 10 or 12 inches, which are stuck into free, 

 light sandy soil, and watered when necessary. A good layer 

 of straw over the surface will contribute very much to their
