THE GENUS FUMARIA IN BHITAIN 57 



has come to light, and I have noticed but Uttle essential variation. 

 In shade-grown or starved plants the leaf-segments tend to 

 become laxer and broader, the pedicels thinner and longer, and 

 the sepals narrower, while near the sea a flattened type of leaf- 

 cutting sometimes prevails. 



There is, however, a well-grown plant in Herb. Mus. Brit., 

 collected by Eidley and Fawxett at Wareham, which seems more 

 permanently distinct. This specimen is much branched, with 

 good flowers slightly smaller than those of the type, and relatively 

 narrow, ovate sepals, laciniate-toothed below, and only 2-2^ mm. 

 in length. In this case the narrow sepals seem normal and are 

 somewhat similar to those shown in the French examples "Billot, 

 Fl. Gall, et Ger. no. 709 " and "i^. micrantha, Societe Dauphinoise, 

 1879, no. 1950 " at Kew. In each of these specimens the sepals 

 are ovate rather than orbicular and approximately twice as long 

 as broad, and as this proportion (sepals 2-4 mm. long, 1-2 mm. 

 broad) is given by Haussknecht as characteristic of the species, 

 he probably examined other similar material, and such plants may 

 be not uncommon in Continental herbaria. But it appears to me 

 that plants with sepals of this kind, though perhaps not a good 

 variety, are distinctly separable from the type of F. micrantha, in 

 which, given good flowers, the sepals are nearly orbicular ; and so 

 I propose to distinguish the Wareham specimen as a form duhia. 

 I suspect the plant of Ziz, originally described by De Candolle, 

 may possibly be referred to this form, which in the absence of 

 fruit may easily be confounded with some states of F. officinalis, 

 and especially with its variety densiflora Pari. French speci- 

 mens of F. officinalis with unusually large sepals have been 

 sent me under the name of F. micrantha Lag. var. Parlatoriana 

 Boiss.
