clay. (Enothera sp. Shrubby, 3 feet high, flowers yel- 

 low. Hab. hilly. Bodegas." This plant from Ecuador 

 has flowers the size of 0. Lamarckiana, many long hairs 

 on the sepals and young leaves, the leaves being rather 

 narrowly lanceolate, petiolate. The plant must have 

 been very much like 0. rubrinervis, though differing 

 somewhat in leaf characters. Ecuador is an unexpected 

 place to find plants having these characters. 



A very interesting sheet bears the name 0. biennis L. 

 var. muricata Torr. & Gray. It was collected by Dr. 

 Wm. M. Bell, of London, in the Raton Mountains (which 

 extend from southern Colorado to New Mexico) in 1867. 

 There are two specimens and several extra flowers and 

 buds. The flowers are as large as those of 0. Lamarcki- 

 ana, the style is long so that the flower is open-polli- 

 nated; the hypanthium and bud cone bear numerous 

 long hairs ; the buds are the precise size and shape of 0. 

 rubrinervis; the stem leaves are more narrowly Lanceo- 

 late than 0. Lamarckiana but are often broad and sessile 

 at base like that form. This plant is strikingly like 0. 

 rubrinervis in every particular, except that the upper 

 stem leaves are perhaps a little narrower. The pre- 

 sumption is that these plants were collected in the wild 

 condition, and I have found no reason for supposing 

 otherwise. This would seem to support the view that 

 these Lamarckiana forms were formerly found wild in 

 the western region, although it has been suggested that 

 the Texas plants, from which de Vries's cultures appear 

 to have originated, were perhaps descended from 

 garden seeds. 



Another very interesting specimen is marked "Onagra 

 guttata Greene n. sp., New Mexico, 1904. Alt. 6600 

 feet." Its leaves are very narrowly lanceolate (much 

 narrower than 0. lavifolia) ; the stems red, with many 

 red papilla? bearing long hairs; the flowers are large, 

 style long, and there are many long hairs on the sepals, 

 which also have red bands like 0. rubrinervis. 



These specimens show that forms having large flow-
