48 BOTANICAL GAZETTE. 



Aristida, probably a new species. The last three species were grow- 

 ing on rocks on the very top of the peak. The first is abundant in 

 rocky prairies near the base of the mountains. I have sent these 

 grasses to Dr. Vasey of the Department of Agriculture, and he has 

 not yet reported definitely about them. 



The sides and part of the top of this great bluff are covered 

 with a thick growth of mountain cedar (Juniperus occidentalism Tax. 

 conjungens), red oak (Quercus rubra), live oak (Q. virens), and shin 

 oak (Q. sinuata, var.?). Among these we noticed the following 

 shrubs; Celtis reticulata, PteleatrifoUata, var. mollis, Moras parvi- 

 folia, Rhus triIobata,and the curious evergreen Berberis trifoliata. 



I have no doubt that the locality is very rich in plants, and the 

 botanist who will visit it in a good season will be well repaid for his 

 trouble, besides the pleasure of viewing beautiful landscapes. 



The settlers about the peak have assured us that they are gen- 

 erally favored with more or less rain while the country 8 or 10 miles 

 distant is suffering from drouth. Some of our own observations 

 seem to corroborate this statement. 



In crossing the Brazos 6 miles from the peak we found on the 

 sandy banks of that river fine blooming specimens of the following 

 species: Heliotropium convolvulaceum, Euphorbia hexagona, Dalea 

 lanata, Aster spinosus,Cycloloma platyphylla, and Enslenia albida. —

North American Grasses.— In the April Naturalist Dr 

 Vasey gives some notes on N. Am. Grasses,based on Mr. Bentham's 

 recent paper on Graminece. As all botanists are interested in the 

 proposed changes we will note a few of those that most concern us. 

 Polypogon is placed under the Panicacew. Thurbera is a new genus 

 made to include two species of hitherto doubtful relations, and 

 most happily named. Sorghum nutans is not Sorghum at all, but 

 Chrysopogon. Sorghum includes only the cultivated S. rulgare and 

 S. Halapense. Muhlenbergia is made to include Vasey a. ' Sporo- 

 bolus includes Vilfa. In Deyeuxia are included all our species of 

 Calamagrostis except two or three which go into Ammophila. All 

 our native species of Aira are referred to Deschampsia. Lepturus 

 paniculatus, Nutt., is referred to Schedonnardus. Eleusine includes 

 Dactyloctenmm. Leptochloafascirularis again appears as Diplach- 

 mfascicularis. Triodia includes Tricuspis and Uralepis. Tnpla- 

 lis appears with two N. Am. species. Our Brizopyrum is Distlich- 

 iss, Raf. Briza includes Calothera. Atropis is referred to Glyceria. 

 Bromus includes Ceratochloa. Our native Triticums are referred to 

 Agropyrum. Gymnostichum is referred to Asprella.
