pare stomata on plants from both West and East, taking those of the same species 

 or genus for comparison. 



I have not yet comi^leted a tabulated list of 100 specimens, so cannot as yet give 

 my figures or draw definite conclusions. The results thus far seem somewhat con- 

 fusing, but I am still inclined to think they will verify my sujiposition, for I find the 

 stomata not only more distant, but somewhat smaller, on Western plants. When I 

 have finished measuring and comparing my list of plants, I can draw more definite 

 conclusions. 



Other interesting things in regard to stomata were also noticed in my study. 

 Almost every narrow-leafed plant studied had stomata on both surfaces of the leaf, as 

 well as on the stem. The grasses and parallel-veined leaves have long, narrow sto- 

 mata, arranged with their major axis parallel to the major axis of the leaf, while the 

 stomata of the net-veined leaves seemed to be scattered irregularly over the surface) 

 regardless of the axis, and somewhat broader than those of the narrow leaves. When 

 there was any difference between the stomata of the upper and under surfaces, those 

 on the lower were broader, in many cases being almost round. 



This subject is very interesting, and there is much yet to be learned about sto- 

 mates, their arrangement, distribution, and size, and their connection with the hab- 

 its or location of various plants. This subject may have been well studied, but if 

 it has been I am unable to find any literature on the subject. This study is very 

 fascinating, so that any botanist cannot help enjoying it or discovering new facts. 



It is to be hoped that other botanists will study the peculiarly Western types of 

 our Kansas flora, and add something definite to our knowledge of their habits, struc- 

 ture, and forms. 



ADDITIONS TO THE FLOEA OF KANSAS. 



BY B. B. SMYTH, TOPEKA. 



The following species and varieties of plants, not heretofore reported, have been 

 found growing within the State during the past two years, and are therefore added 

 to the list of Kansas plants. Descriptions are given, as far as possible, of all plants 

 not described in Gray's Manual (6th edition), or Coulter's Manual of Rocky Moun- 

 tain Botany. Many of the descriptions are obtained from Coulter's Manual of the 

 Phanerogams and Pteridophytes of Western Texas, being Contributions from the 

 United States National Herbarium, vol. II. Descriptions of some of the plants are 

 not at hand, and their existence in the State, though here reported, is not absolutely 

 certain. 



FLOWEBING PLANTS. 



1. Anemone patens L.: Linn county ( Mrs. A. H. Merrell). 



2. Delphinium carolinianum Walter: Stems 8 to dm. high, slender, often softly 

 pubescent; leaves deeply 3- to 5-parted, the divisions two to three times cleft; the 

 lobes all narrowly linear; raceme strict; flowers whitish; spur ascending; pods erect. 

 Frequent on rocky hillsides; our most common delphinium; heretofore known as 

 D. azureum Mx. (Smyth). 



ii. Delphinium scopulorum Gray: Pottawatomie county (collected by F. F. Creve- 

 coeur, and determined by Prof. L. H. Dewey). 



4. Draba caroliniana Walt., var. micrantha Gray: Franklin county (collected by 

 Prof. W. E. Castle). 



5. Erysimum asperum DC, var. arkansanum Gray: Sherman, Wallace, Finney 

 and Hamilton counties (S.)
