Teucrium laclniatum Torr., referred of late by Dr. Torrey to 

 T. Cubense L., which is also from Texas, appears to be quite clearly 

 distinguished, by a lignescent perennial root, finely divided leaves 

 which are usually somewhat scabrous-pubescent, larger corolla, and 

 minutely reticulate (rather than punctate) nutlets destitute of longitu- 

 dinal thickened ribs. 



2. Determination of a Collection of Plants made in Oregon by Eliiiu 

 Hall during the summer of 1871, with Characters of some New 

 Species and various Notes. 



1. Clematis ligusticifolia Nutt. in Torr. & Gray, Fl. l,p. 9. 



0. Thalictrum occidentale, n. sp. T. dioico simile : stigmate 

 longiori ; carpellis elongatis (maturis ad semipollicarem usque) fusifor- 

 mibus parum ingequilateris subangulatis costis acutissimis 8-10 per- 

 cursis acuminatis, stipite brevissimo seu vix ullo. — I have a fruiting 

 specimen of this from the Kew distribution of the collections of the 

 British Oregon Boundary Commission, ticketed Vancouver's Island, 

 Dr. Lyall and C. B. Wood ; and a memorandum notes that Dr. Engel- 

 mann's herbarium contains a specimen of the same, collected in Mon- 

 tana by Professor Swallow. In the present collection made by Mr. Hall 

 two or three fruiting specimens also occur. There are from 5 to 10 or 

 12 carpels to a flower, of which a few only seem to mature. The 

 contrast between the short ovary and the long fruit is remarkable. To 

 this may belong a specimen of Nuttall's collection, named T. hetero- 

 phyllum, in flower only, arid a similar one in Mr. Spalding's Clearwater 

 collection. But materials are wanting for the identification. 



2. Anemone deltoidea Hook. Fl. Bor.-Am. t. 3. In fruit. 



3. Trautvetteria palmata Fisch. & Meyer. ; forma occiden- 

 talis, T. grandis Nutt. 



4. Ranunculus (Batrachium) heterophyllus Weber. ; the 

 larger specimens (4 a ) nearly equalling the var. peltatus (i?. peltatus 

 Schrank) : new to this country. 



5. Ranunculus Cymbalaria Pursh. Fl. p. 392. 



0. Ranunculus alism^efolius Geyer, a large form. For this, or 

 rather for the dwarf and slender form, my var. alismellus, there is 

 apparently an earlier name, R. Pseudo-Hir cuius Schrenk, Enum. PI. 

 Nov. 2, p. 65 (from Moscow Bulletin), 1842, which is not mentioned in 

 Walpers and has been totally overlooked. Professor Godet kindly 

 called my attention to it, and pronounced it the same as Bolander's no. 

 6258.
