is a most remarkable plant, not at all related to Leptotaenia. 

 Dedicated to Wm. C. Cusick, one of the best and oldest of our 

 collectors. Cusickia minar n. sp. character of genus. 



Coulter and Rose have been careless in drawing up the 

 generic character of Leptotaenia. They say "oil tubes 3-6 m 

 the intervals,"' and yet nearly half their species do not have 

 even three oil tubes in the intervals. 



Leptotaenia multifida var. Eatoni (C. & R. Rev. Umb. 'z'l 

 (1888) as species). This cannot be maintained as a species; 

 it grades imperceptibly into the type species. The more dis- 

 sected forms around farther north and in the Sierras, but inter- 

 mingle. 



Cogswellia bicolor is reported by me from Idaho by Coul- 

 ter and Rose on page 237. This was an error of mine, as the 

 plant is C. leptocarpa, which is its nearest congener. It has 

 the same moniliform roots and the same peculiar habitat, but 

 differs in the shorter fruit, and broader and with thicker wing 

 and the peculiar filiform leaf divisions which are the only per- 

 manent distinctions. No. 2414 Cusick distributed as Leibergia 

 crogenioides ? is nearer it, but still clearly C. leptocarpa. I 

 have seen no typical specimens of this species out of Utah ; all 

 others are leptocarpa. which is a seemingly good species. 

 Coulter and Rose are in error in placing it with C. anomala 

 and the nudicaulis group. Though that is nearest related to 

 the ambigua group, yet they have separated them by the 

 whole width of the genus, the groups differ, however, in the 

 roots. The utriculatum-caruifolium group Coulter and Rose 

 have confused. My No. 3172. which they refer to 

 utriculatum, is not utricidatum. It ha

 but there are certainly not three. I have abun- 

 al of utriculatum from Vancouver Is. which

 rrey and Gray, the fruit being 3 lines long and 2 

 ovate-oval to oval-ellipttc, wings wider below and 

 idth of body and much prolonged beyond the base 

 and but very little above it; the oil tubes are large 

 on the face and 4-6 on the commissure, the
