384 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



deposited here, and the advent of the Oenotheras is doubtless 

 from one or other of these two sources. 



The plants closely resemble the "Isle of Wight" race of (E. 

 Lamarckiana (to be described in a book now in process of pub- 

 lication) and the species as it generally appears in English 

 gardens. The rosettes in this colony differ in having green 

 midribs (both dorsally and ventrally), or pink midribs (both 

 dorsally and ventrally), but the depth of red varies. The same 

 applies to the stem-leaves. This is curiously different from 

 other races, such as (E. mut. rubrinervis, in which the midribs 

 are red dorsally and green ventrally. The rosette leaves are 

 usually nearly or quite smooth, but some may be crinkled. 

 The plants were short, their average height being about twenty- 

 two inches, though some reached a height of over three feet. 

 The stems bear many red papillae. The smaller plants were 

 unbranched, the lower stem-leaves being closely crinkled and 

 curled while the upper leaves and bracts are often quite smooth. 

 A peculiarity of the race was the irregular disposition on the 

 stem of much-crinkled and nearly smooth leaves, without 

 gradual transitions between them such as usually occur in de 

 Vries's race of CE. Lamarckiana. Not infrequently crinkled 

 and smooth leaves alternate. The buds have fewer long hairs 

 than in the above mentioned race, and the sepals have uniformly 

 the red color pattern 5-7 of (E. mut. rubrinervis, though they 

 vary somewhat in depth of shade. The dimensions of the 

 flowers were as follows: bud cone 50 mm., hypanthium 43 mm., 

 ovary 11 mm., diameter of cone at base 11 mm., length of petals 

 50 mm., width 60 mm. One plant was identical with the race 

 of de Vries, except in its larger flowers, reddish sepals and fewer 

 long hairs. In most plants there is also a strong distinction 

 between the smooth and crinkled leaves. 



This colony differs, therefore, in minor peculiarities from 

 any race of (E. Lamarckiana previously observed, and it ex- 

 hibits a relatively narrow range of variation. 



Along the electric railway tracks north of Liverpool, between 

 Crosby and Hightown, an equally extensive and uniform colony 

 of (E. biennis was found. Thousands of plants, in flower and 

 rosettes, were growing on uncultivated land with a nearly pure 

 sandy soil, behind the coast range of sand hills in a long narrow
