Delphinium stachydeum (Gray), n. comb. — D. scopulorum 

 Gray var. stachydeum Gray, Bot. Gaz. 12:52. 1887. — O ne °f tne 

 most readily distinguished species of the group to which it belongs. 



Meconella linearis (Benth.), n. comb. — Platy stigma linearis 

 Benth. Trans. Hort. Soc. II. 1:407. 1834; H es per omecon linear e 

 (Benth.) Greene, Pitt. 5:146. 1903. — Greene (op. cit.) has called 

 attention to the earlier and valid Platystigma of Robert Brown. 

 In our judgment, however, Besper omecon Greene is not distinct 

 from Meconella Nutt. 



Horkelia Tweedyi (Rydb.), n. comb.— Ivesia Tweedyi Rydb. 

 N.A. Fl. 22 : 288. 1908. — This plant was long included in the nearly 

 related but much more southern H. utahensis (Wats.) Rydb. It 

 is consistently distinct from that species, however, and seems to be 

 confined to Washington on the eastern slope of the Cascades. In 

 making this transfer we would call attention to our remarks in 

 Box. Gaz. 55 : 375. 1913 on the fallacy of maintaining certain segre- 

 gate genera in this group. 



Trifolium Kennedianum (McD.), n. comb. — T. involucratum 

 Ortega var. Kennedianum McD. N.A. Trif. 56. 1910— The broad, 

 equal, entire involucral teeth readily distinguish this plant. In 

 the species to which it was referred, the .involucral teeth are some- 

 times entire, but narrower and very unequal in length. 



Cardamine cordifolia Gray var. Lyallii (Wats.), n. comb. — 

 C. Lyalli Wats. Proc. Am. Acad. 22:466. 1887; C. cordifolia Gray 

 subspec. Lyallii (Wats.) O. E. Schulz, Engl. Bot. Jahrb. 32:438. 

 I 9©3-— Schulz is undoubtedly justified in no longer maintaining 

 this plant as a species. We give it varietal rank that it may accord 

 with those variations deemed unworthy of specific status, and then 

 treated as varieties by most American botanists. 



CLARKIA and its near allies— In Box. Gaz. 52:267. 1911, 

 there were separated from Clarkia some species that are evi- 

 dently aberrant in that genus. It is very doubtful whether the 

 restoration of the genus Phaeostoma relieved a difficult situation. 

 Granting that Phaeostoma has 8 fertile anthers while Clarkia has 

 only 4, separating on this basis creates an equal difliculty between 

 Godetia and Phaeostoma in that both have 8 stamens and the latter 

 may have petals either clawed or not clawed. But the same is true
