 CONTRreUTIONS FROM THE U. S. NATIONAL HERBARIUM, VOL. I, 



No. 4, June 30, 1891. 



List of plants collected in western Mexico and Arizona, 

 J. N. Rose (pp. 91-127, plates 10). — This includes lists of plants col- 

 lected by Dr. Edward Palmer in western Mexico (at Alamos) and Arizona 

 in 1890, with descriptive notes on 45 new species and several new 

 varieties. The new species illustrated in the plates accompanying the 

 bulletin are, Stellaria moyitana, Diphysa racemosa^ Evhinopepon cir- 

 rhojyedunculatus, Tithonia fntticosa, liidcns nlamosanum, Ilymenatherum 

 anomalum, Perczia montana, Cordia sonorw, Ipomoea alata, and Tahebuia 

 palmeri. 



Among the plants of thi8 collection are many very beautiful ones which should 

 claim the attention of cultivators. Of tiieso we cite Hetcropterya portillana, a recent 

 Hpecies describerl by Mr. Watson. This is especially attractive for its large clusters 

 of red fruit. It is very common at Alamos, and could easily be obtained for cultiva- 

 tion. 



Gal2)himia humholdtiana, a rare plant in herbaria, ia a common and attractive shrub 

 of the mountains here. It is 6 to 8 feet high, with a handsome top, large racemes of 

 yellow flowers, and attractive foliage. 



Cordia sonorce is a new species, a very beautiful shrub or sm.all tree, and an abun- 

 dant bloomer. 



Tahebuia palmeri, another new species, is a conspicuous tree of this region. It 

 grows to the height of 25 feet and produces large clusters of flowers. 



Three or four of the Ipomroas are very attractive ; one is a tree 30 feet high; 

 another is a climbing shrub (/. hracteata), with large, conspicuous bracts, which give 

 the plant a very showy appearance; two other new species are high-climbing vines.

Manual of the phanerogams and pteridophytes of western 

 Texas, Polypetal>s:, J. M. Coulter (pp. 156, plate 1). — This is the 

 first part of a manual intended to include descriptions of all Texan 

 plants west of the ninety-seventh meridian. The rich flora of this 

 region has never before been systematically described. It is believed 

 that the manual will be of service to botanists and students not only
