as the " granadilla," and by some much appreciated. To insure 

 fruit, the flowers must be fertilized artificially. 



The most attractive and useful of the greenhouse kinds are — 

 P. coerule.2 racemosa, a very free-floweriug form of this well known 

 and comparatively hardy species; P. hyhrida Jlorlbunda, a most 

 handsome hybrid ; P. Imperatrice Eugenie, a very beautiful hybrid, 

 especially adapted for planting in conservatories, frequently illu- 

 minated with gas, as burnt air does not injure it in any appreciable 

 degree. It is also capable of resisting the deleterious eflects of 

 smoke and dust, and is, therefore, better suited for conservatories iu 

 towns than any of the others. P. Lawsoni, P. pahnata, and P. 

 ShepjmrcU are also worthy of a place where space can be found for 

 them. For outdoor culture P. ccurulea is the most desirable. 



The Tacsonias, which are nearly allied to the Passifloras, and 

 thrive under the same management, are mostly very beautiful. The 

 best are, T. Buchanani, flowers brilliant scarlet, produced freely on. 

 small plants ; T. fioribunda, another beautiful kind, requiring, like 

 the preceding, a stove temperature ; T. exoniensis, bluish mauve, a 

 fine free-flowering hybrid of recent introduction; T. 'ina7iicata,fioweTa 

 scarlet, useful for cool houses ; T. mollissima, a very strong grower, 

 with pink flowers, useful for very large houses; T. Van-Volxemi, one 

 of the most beautiful of conservatory climbers, the flowers are of 

 the most brilliant red, and borne on slender stalks of a great length ; 

 indeed;, the stalks are so slender, that the flowers have the appear- 

 ance of being suspended by threads. The flowers are borne in 

 great profusion, and established plants produce a large number of 

 its oval-shaped fruit. 



The new T. insignis, figured and described iu Bof. Mag., t. 6069, 

 is one of the very finest species belonging to the genus, and in time 

 will become as popular as the well-known T. Van-Volxemi. The 

 flowers are of a gigantic size, the sepals rich violet crimson, and 

 the petals reddish crimson. The ample foliage is of a bright glossy 

 green, giving the plant, even when not in flower, a very attractive 

 appearance. It was raised by Mr. Anderson, gardener at Sowerby 

 House, Hull, from seed received from South America some years 

 previously. 



SUMMEE MANAGEMENT OE GREENHOUSE PLANTS.

HEN azaleas, camellias, heaths, and a few other hard- 

 wooded plants, are grown in structures specially devoted 

 to them, as in the case of big gardens and trade col- 

 lections, it is, perhaps, advantageous to keep them in- 

 doors during the summer season, but it is very ccttain 

 that in the case of mixed collections it is in every way better to 

 place them out of doors during the summer. In doing this a certain 

 amount of caution is needful, so that they may not be exposed to the
