throughout the State but has escaped notice till lately, doubtless 

 from its resemblance to the last. 



Mimulus moschatus v. longiflorus, Gray, is called M. inodorus, 

 n. sp. and described as "scentless, possibly only annual; certainly 

 never rooting at the joints." But it is certain that the plant of 

 the mountains of this county, called the musk plant, is not scent- 

 less; I believe roots at the joints and is an annual. Mr. Greene 

 probably had another plant than Gray's var. of M. moschatus. 



Mimulus androsaceus, Curran, seems identical with the plant 

 distributed under the name M. Palmeri, in its turn evidently a 

 robust form of what Dr. Gray named M. exiguus, which name 

 has priority. 



The shrub so often collected near San Diego and called Erio- 

 dictyon tomentosum, Bth., is now referred to E. crassifolium, Bth. 

 by Mr. Greene who writes that the former name belongs to a 

 Monterey plant. A new species from the vicinity of Todos Santos 

 bay is named E. sessilifolium, which has been collected by several 

 and heretofore distributed as a variety of E. angustifolium, or 

 under Dr. Parry's MS. name, E. intermedium. These are all gen- 

 erally known as Yerba Santa and seem to run very near each 

 other. 



Engelmann's Quercus Palmeri seems to have been first des- 

 cribed as a species by Kellogg as Q. Dunnii. 



Mr. Geo. C. Deane has found near his place at El Cajon the 

 following that are not on my check-list; Gnaphalium decurrens, 

 var. Californicum, Gray; Baeria tenella, Gray; Euphorbia albo- 

 marginata, Torr. & Gray. 



The plant distributed as Baeria Clevelandi, Gray, is only a var. 

 of B. gracilis instead.
