A typo differt bracteis brevioribus pedicellos dimidios vix superantibus, 
floribus paulo minoribus, et presertim fructibus multo minoribus circa 
2:75 mm. longis ac latis eum mucrone brevissimo obtusissimis. 
Hee species, quee Algeriam et Tunisiam habitat, per flores pallidos maximos 
et petalorum exteriorum (preesertim inferioris) alas latissimas notabilis est. 
A F. agrariá sepalis tenuibus anguste carinatis, corollis latioribus, fructuque 
plus minusve mucronato densius rugoso differt. F. major, Bad. corolla 
angustiore alis atropurpureis reflexis rosea et fructibus minoribus obtusioribus 
precipue distinguitur, sed quod ad fructum pertinet, varietati platyptere 
simillima est. 
The diagnosis of this fumitory, the finest-flowered of all the genus, is 
based on Boissier’s specimens, together with Cosson’s plant at Kew, the 
E. G. Paris example in Herb. Mus. Brit., which shows extremely fine flowers 
but unfortunately no fruit, and Reverchon’s plant in Mr. C. Bailey's 
collection. The last-named bears fruit more like that of F. major than of 
Boissier’s type, but the remarkably broad wings and the colouring of its 
corolla render it impossible to mistake its closest affinity, and it is therefore 
placed as a variety under F. atlantica.

This species is perhaps the F. vulgaris corubensis alba (sic) of Parkinson 
(Theat. Bot. 287 (1640)), noted as growing in cornfields in Cornwall. 
In addition to the characters already given whereby this plant may be 
distinguished from F. agraria, Lag., it may be remarked that the colour of 
its corolla is a elear rosy-white, quite without the yellow and greyish tints 
which mar the brightness of the flowers of Lagasca's plant, and its upper 
petal is less obtuse with the wings distinctly reflexed upwards as in F. major, 
Bad.
