to the heads and short pedicels to the flowers. This last is 

 Trifolium pratense var. parviflorum, and has the following 

 synonymy : —

 Babington's type-specimens from Elgin, as well as others from 

 Plymouth and Walton-on-Naze, and a type of Lange's figure 

 have been accessible to me in the Herbarium at Cambridge ; a 

 type of Knaf's name, collected by Auerswald in Bohemia, has been 

 seen in the Botanical Department of the British Museum of Natural 

 History, South Kensington ; at the Royal Gardens, Kew, are speci- 

 mens collected at Fairmile in Surrey, at St Leonards, at Tonbridge 

 Wells, and at Elgin, from the herbaria of Borrer and H. C. Watson, 

 and from near Bordeaux, collected by C. des Moulins ; and I have 

 myself collected it at Hunstanton in Norfolk, Gatton Park in 

 Surrey, Waltham St Lawrence in Berkshire and (in company with 

 Mr G. Nicholson) near Heiligenblut in Carinthia — on each occasion 

 a single root. All these specimens agree very closely. 



The first definition of the variety parviflorum runs : " heads 

 more or less stalked : calyx-teeth as long as, or longer than, the 

 corolla," and is correct as far as it goes. Celakovsky's description 

 is "Ahren grosstentheils gestielt ; Bliithen langer oder ktirzer 

 gestielt ; Deckblatter theilweise ausgebildet ; Griffel ktirzer als 

 die Stau bgefasse." But the following is fuller and more in accord 

 with the specimens : — plant not robust ; heads more or less stalked ; 

 bracts sometimes developed ; corolla in the mature flower crumpled 

 at the base within the calyx and not exceeding the longest of 

 the calyx-teeth ; pistil becoming foliaceous, the ovarial part linear- 

 lanceolate, and often open above ; ovules more or less aborted. 



Examination of buds not ready to expand reveals no crumpling 

 of the corolla ; so that this evidently takes place in the rapid 

 growth of the tube which precedes the expansion of the flower; 

 and it is impossible to resist the assumption that the unusual 

 size of the ovary and the narrowness of the mouth of the calyx 

 are the causes of it. 



Phyllody of the ovary to a greater degree than in typical 

 parviflorum is not uncommon in Trifolium, pratense ; less modifi- 

 cation in this direction I have found in a plant from Glen 

 Clova, Forfarshire, where the peduncle and pedicels were un- 

 developed, but the corolla crumpled and the ovary elongated,
