the open border, in a mixture of sand and peat, in patches 

 amongst the Azaleas. It is perhaps best to take up the 

 bulbs,' and dry them, when the seed is* ripe ; but I have left 

 African Gladioli unmoved for several years, in the border. 

 I have never seen the least approximation to each other in 

 the natural seedlings of G. blandus, G. tristis, G. cardinalis, 

 G. hirsutus, aud G. recurvus. 



The only mule Pancratium I have raised, is between P. 

 rotatum and P. distichum ; I had about a dozen very fine 

 seeds, but only one vegetated, and the rest, though above 

 an inch in length, proved to have no germ. 



Besides the mule Rhododendron, figured in the Botanical 

 Register (Plate 195,) 1 have two that were produced by the 

 accidental fecundation of a white-flowered Azalea by the 

 dust of a Rhododendron Ponticum, that stood by it : one of 

 these has produced fragrant whitish flowers very abundantly, 

 having generally nine but occasionally ten or eight anthers. 

 I distinguish it by the name of Rhododendron hybridum 

 enneandron. I raised, three years ago, twenty-four plants 

 from Rhododendron Ponticum, touched with the dust of 

 Azalea Pontica, the plants having been forced in the stove, to 

 make the experiment certain ; but the seedlings were very 

 weakly, and all died before the winter. I have young seed- 

 lings since raised, which should be mules ; but I cannot rely 

 upon them, because the dust of Rhododendrons is often 

 carried by the wind to a great distance. 



I have a very ornamental mule Oenothera from Oe. 

 glauca, and (if my memorandum is right) Oe. suffruticosa, 

 which produces seed and seedlings like itself. 



I have not made many experiments with Passion-flowers,
