thus {unknown to me) seems to have the same character. Anoth- 

 er character that shows the foil}' of separating the species of this 

 genus is in the pod which in the elegans class is ovate-acuminate 

 and long-styled, while in Frcmontii anil the yelloir-flowereiTforins 

 it is oblong and nearly truncate at tip with very short styles. 

 The leaves of the white-flowered forms are naturally glaucous and 

 light-colored, flat above, and normally broad though narrow, in 

 small forms. The leaves of the yellow-flowered class are a peculiar 

 yellowish-green, always narrow and triquetrous or channeled in 

 or near the tip. The bulbs of the white-flowered class are shallow, 

 that is near the surface, the others deep in the ground Rvd berg's 

 Z. intermedius, acutus and gramineus arc forms of venenosus and 

 falcatus is a form of paniculatus, all these he puts in ToxicoK-or- 

 dion. AnticJea Coloradoensis is the high altitude form of Z. eh- 

 gans and is the s&me as Blankenship's Z. alpinus. Z porrifolius 

 Greene which has been distributed by Woo ton both as Mexieanu- 

 and porrifolius (both named by Greene) is as i have said an extreme 

 form of elegans, just as my Z. Fremotii var. brevihractennis is an 

 extreme form of that species, Miss Eastwood's Z. micranthus is 

 the same and her Z. exaltatus a large form of Fremontii. Z. ion. 

 gus Greene is a green-flowered form (a common state also in Ve- 

 ratrum) and is the same as one of my specimens from A. Nelson 

 marked "Z. dilatatus Greene". Z. chloranthus I do not know, but 

 it cannot be maintained on the characters given by Robinson and 

 Fernald in the Manual as distinct from elegans of which I have 

 plent of material from near Pursh's type locality as' well as".else- 

 where. Z. Mexicanus (Townsend & Baker, named by R»>bi« son) is 

 the same porrifolius form of elegans and corresponds with other 

 material from Black Mt. N". M. (Wooton as elegans) and from the 

 Mogollons (Wooton as Mexicanus). 



In the May Bulletin Eydberg indulges in sortie puerile petti- 

 fogging to escape, but cannot answer, my criticisms. In Contribu- 

 tions 12 77 I attacked his work showing the inaccuracy of his de- 

 scription of Z. intermedius of which my No. 2o!ii is one <»f the 7 

 types on which he founded the species. In answer he sa\s t hat the 

 first specimen was the type "and therefore he is not more accurate 

 than I". Rydberg evidently does not know the difference between 

 a type specimen and a type. If with material from six other local- 

 ities before him he deliberately ignored them and founded his spe- 

 cies on the one Sand berg specimen the botanical world will not seek 

 to find the cause of his poor work. Everyone else knows that all 

 material passed under review is a part of the type unless differing 

 enough to be noted by the author.
