THE WEST AMEEICAN SCIENTIST. 15 



BOTANICAL NOTES. 



Among the later publications received, are the supplements and indexes to the 

 Synoptical flora of North America, by Dr. Asa Gray. From the supplements wo 

 gather the following notes which will be of interest to our botanical readers, especi- 

 ally those who may have received portions of the editor's distributions of herbarium 

 specimens. 



Pentachaeta paleacea, Greene, founded on a few fragmentary specimens, is refer- 

 red to P. aurea, Nutt. 



Franseria chenopodifolia, Benth., found abundantly in the Tijuana valley, 

 north of the U. S. boundary, and south to Magdalena bay, is given in my check-list 

 as F. deltoidea, but was distributed under its true name. 



Nemacladus tenuissimus and N. cappillaris, Greene, are given as synonyms of 

 N. ramosissinus, Nutt., while N, pinnatifidus, Greene, is reduced to a varietal rank, 

 as are also N. montanus and N. rube?cens, Greene, both of the last under the one 

 name, var. montanus. 



Arctostaphylos arguta? var. diversifolia, Parry, is raised to specific rank as A. 

 diversifolia. Parry. 



Collomia, and certain bractless species of Loeselia are incorporated into Gilia : 

 thus Loeselia tenuifolia, L. Matthewsii and L. guttata become gilias, along with 

 Loeselia effusa — now Gilia Dunnii, Kellogg. 



Eucrypta is referred back to Eilisia, and Eucrypta paniculata, Nutt, (vide Greene) 

 is described as Eilisia Torreyi. var. Orcuttii, n. var. 



Phacelia suffrutescens. Parry, is considered as of varietal rank only, and a new 

 species closely related to P. Orcuttiana and P. Fremontii, is described, which was 

 collected on the mountains of Lower California and has been sparingly distributed 

 under the herbarium number, 1087. 



The Eriodictyons are briefly treated, three species only being recognized; E. 

 angustifolium (with var. pubens) being connected with E. glutinosum. The other 

 two species are E. sessilifolium, Greene, (distributed under the manuscript name 

 E. intermedium, Parry, and also as a variety of E. angustifolium), and E. tomento- 

 sum, Benth. 



A revision of Mimulus is given, in which Dr. Gray prefers an arrangement of 

 the genus under five subgenera to a division into various genera. He recognizes 

 only two species under the section Diplacus, M. glutinosus and M. puniceus, and. 

 his arrangement differs in various other res].ects from that of Mr. Greene. M. in- 

 odorus, Greene, is made M. moschatus var. sessilifolius ; Greene's M. guttatus is re- 

 ferred back to M. luteus ; M. androsaceus, Curran, is made a var. of Palmeri ; and, 

 the re-establish ment of the older name, M. exilis, Durand, in place of M. pilosus, 

 "Watson, are some of the changes. 



The plant hitherto referred to Aphyllon Ludovicianum, Gray, is referred to A, 

 Cooperi, Gray. 



Trichostem a Parishii, Vasey, is reduced to a variety of T. lanatum. 



Monardella nana and M. tenuiflora are both given as varieties of M. macrantha. 

 The plant distributed from the mountains of San Diego county as M. nana belongs 

 to M. hypoleuca, Gray.
