ones have treated. The plants discussed are Euphrasia officina- 

 lis; Gaura and Oenothera: the carpellary structure of Nymphsea; the 

 sexual characters of Rhus; Ruhus Chamcemorus, Dalibarda repens; 

 some morphological distinctions in the genera of Ericaceae; vitality of 

 seeds in Lysimachia atropurpurea; Campanula rotundifolia; Cornus Can- 

 adensis; Aralia hispida; Ltizula, campestris, Cakile Americana, Hyperi- 

 cum ellipticum, Trifolium hybriduni; Lathyrus maritimus; Lonicera cceru- 

 lea; Raphamis sativus; the nature of the verrucae in some Convolvula- 

 ceae; Polygonum cilinode; Aster Tatarica. The observations are of a 

 kind to be readily made by anyone with leisure and access at all 

 hours to living plants, and require no great knowledge of systematic 

 botany, yet they are of great general interest, and more attention to 

 the physiology of plants would attract to their study many now de- 

 terred by the somewhat dry details of herbarium work. 



List of Plants of Los Angeles County, California. By Anstruther 

 Davidson, M. D. Local lists are always useful even if very 

 incomplete — they stimulate search. The next issue will probably 

 contain a much larger number. There are many in the herbarium 

 of the California Academy of Sciences, from Los Angeles County, 

 not mentioned in this. In Oxytheca.for instance, O. trilobata grows at 

 Ravina, and O. lutea at Lancaster. Boisduvalia cleistogama is 

 probably an error of determination. The rather numerous printer's 

 errors will of course be rectified in subsequent editions. 



Flora Washingtoniensis. By W. N. SuKSDORF,is a list of the flow- 

 ering plants and ferns of the State of Washington. These lists are 

 of great service in the study of the distribution of plants. Washing- 

 ton is a highly objectionable name for a State, as it requires always 

 an explanatory phrase to distinguish it from the better-known seat 

 of the general government. 



Contributions from U. S. National ILerbarium. Vol. i. No. vi. 

 i. List of plants collected by C. S. Sheldon and M. A. Carleton in the 

 Indian Territory in 1891. By J. M. Holzinger. ii. Observations 

 on the native plants of Oklahoma Territory and adjacent districts. 

 By M. A. Carleton. Two new species IpomcBX Carletoni Holz and 

 EupJiorbia strictior Holz are described, with plates, and Euphorbia 

 polyphylla Engelm is characterized. Many interesting observations 

 on the relationship of allied species and the distribution of plants 

 are scattered through the papers.
