SO that in point of fact the two plienomena are certainly correlated 

 in the four cases so far observed, and I am sanguine that this may 

 form a clue to further discoveries. 



It is to he observed that soral apospory is associated with 

 both deciduous and evergreen species, and that the additional 

 robustness remarked in the Polysticlmm may be attributed to the 

 fact that as an evergreen Eeru the fronds would not fall until 

 very much later than in the case of a deciduous one, and mani- 

 festly the prothalli could only find a congenial nidus for full de- 

 velopment when brought in contact with the soil by the decay of 

 the parent frond. With regard to Athyrium Filix-foemina, var. 

 cJarissima it is remarkable that the aposporous fronds remain 

 green much longer than the normal forms under quite similar 

 conditions, the reproductive organs evidently acting as a 

 sustaining power. 



In conclusion I should add that it is due to the courtesy and 

 generosity of Mr. Stausfield, whe has provided me with one frond 

 out of the two affected, that I am enabled to give this description 

 of the case from personal observation. The whole of the material 

 has been laid down for culture ; but a portion is available for 

 microscopic examination with a view to the further elucidation of 

 the phenomenon ; meanwhile, however, I thought it well to make 

 a preliminary record of the matter, and of my observations as 

 far as they have gone. 



Note on Prolonged Suspended Vitality in a Fritillary Bulb. 

 By C. Packe, P.L.S. 



[Read 20th June, 1889.] 



In 1876 I visited the Maritime Alps specially with the object 

 of finding a yellow Fritillary, which was indicated as having been 

 found there by Moggridge. 



On June 16th of that year, in the Val Ammolina above Limone, 

 north of the Col di Tenda, I found the Fritillary, and gathered 

 five plants which I brought home, and having ])reserved three 

 specimens dried in iny herbarium, I planted the other two in a 

 marked spot in my garden, probably in July, but I do not know 

 the day. 



The next year I looked in vain for the Fritillaries to come up 

 and also in the year succeeding. There were no signs of them, 

 and 1 concluded that, as in the case of so many other Alpine 

 plants when transplanted, that the uncongenial soil and climate 

 had proved fatal and that the bulbs had perished. 



On May 5th this year my wife drew my attention to a new 

 yellow Fritillary that had made its appearance in the garden, and 

 there, on exactly the spot where I had planted it, was a perfectly 

 grown plant and flower of the same yellow Fritillary after a lapse
