petals 5 free virescent ; stamens 5 hypogynous, free ; carpels 2 free, 

 leafy, placed right and left of the axis ; ovules abortive. No one will 

 doubt the propriety of putting this latter under the head of regular 

 peloria, in association with virescence. The " diagram " for these 

 two flowers is of course absolutely identical. I take it both these 

 instances may be accounted for on the supposition that we have in 

 each case, an arrest of development (not of growth) in consequence of 

 which certain changes which ordinarily occur during growth have not 

 been effected, and the consequence has been that the two flowers retain 

 their primordial congenital disposition of parts. I cannot venture to 

 think how long ago it must have been that an TJmbellifer and a Scro- 

 phulariad originated from a common type ! It only remains for me to 

 add tliat the specimens were sent to me by the kindness of Mr. New- 

 bould and Dr. Hogg respectively. — Maxwell T. Masters.

INTRODUCTORY REMARKS ON THE THIRD AND LAST 

 SUPPLEMENTARY PART OF THE FLORA DANICA. 



By J. Langh. 



A RoFAL Decree of October 9th, 1874, ordered the addition to the 

 Flora Danica of a Supplement, to contain those plants of Sweden and 

 Norway which do not grow wild in Denmark or had not been already 

 figured in the work, which up to 1814 included also the flora of Norway. 

 The extent of this Supplement was at the same time limited to one 

 volume of the same form as the principal work, to be composed of 

 three parts, each with sixty plates. This undertaking, by virtue of 

 which the Flora Danica represents the vegetation of the whole of 

 Scandinavia and the northern Danish possessions (Greenland, Iceland, 

 Faroe Islands), was initiated in 1854, when the late Prof. Liebmann 

 presented to the Royal Academy of Sciences, at its session of April Ist, 

 the first part. More recently, in 1865, I have published the second, 

 and the tliird, which I have now the honour of presenting, terminates 

 the volume.

The geographical limitation which it was at first intended to 

 establish in the Supplement, restricting it to the plants of Norway 

 and Sweden and the main book to those of Denmark and its northern 

 possessions, has not been very strictly carried out. It had been 

 already broken into by the introduction in the earlier parts of a large 

 number of Norwegian plants, and in the same way the plants of 

 Norway and Sweden when they present any particular interest will be 

 admitted occasionally into the three parts of the main Flora which still
