Notes upon the "Description of New Plants from Texas, by S. B. Buckley," 

 published in the Proceedings of the Academy of Natural Sciences of Phila- 

 delphia, Dec. 1861 and Jan. 1862. 



BY ASA GRAY. 



Having for many years past taken a prominent part in the study of Texan 

 botany, as made known by the ample collections of Berlandier, Drummond, 

 Wright, Lindheimer, Thurber, and others, and being under the necessity of 

 keeping, as nearly as possible, au courant with all publications upon the sub- 

 ject, I was naturally much interested in the appearance of Mr. Buckley's two 

 papers, and not a little surprised at the large number of new species which he 

 had gleaned in such a well-harvested field. Accordingly I applied for speci- 

 mens of the plants in question ; and Mr. Buckley an early correspondent of 

 Dr. Torrey and myself promptly and obligingly has placed in my hands, for 

 examination, nearly the whole original materials upon which these new genera 

 and species were characterized. These materials I have examined and com- 

 pared with my own herbarium, calling in the assistance of Dr. Torrey in those 

 orders in which I am not proficient ; and I report the results herewith, with 

 the request that, if favorably received by the Academy, they may be printed 

 in its Proceedings. 



I take the species in order, as they stand in Mr. Buckley's papers. 



1. Clematis Texensis, Buckl., is C. Viorna, var. coccinea, Gray, PI. 

 Wr. 2, p. 7, C. coccinea, Engelm. The latter name would have preference ; 

 but I see no reason for changing my published opinion, that it is a mere va- 

 riety of C. Viorna, although a striking one. Mr. Buckley's character would 

 have been better had he described the cauline leaves from the specimen in 

 Mr. Durand's herbarium, the " foliolis pusillis, segmentis lanceolatis acutis " 

 being from an imperfectly developed leaf. The leaflets are usually rounded. 



2. Clematis Coloradoensis is founded on a very insufficient, thin- 

 leaved, not fully developed specimen of a common Texan form of C. Pitcheri, 

 Torr. and Gray. The leaves are plainly pinnate. 



3. Streptanthus glabrifolius is a large S. hjacinthoides, Hook. 



4. Streptanthus Brazoensis is S. petiolaris, Gray, PI. Fendl. p. 7, PL 

 Lindh. 2, p. 143, PI. Wr. 2, p. 7, &c. 



5. Lepidium Texanum is L. intermedium, Gray, PI. Wr. 2, p. 15. 



6. Arenaria (Alsine) monticolais.4. Benihamii, Fendl., Torr. and Gray, 

 Fl. 1, p. 675. 



7. Sida Sabeana is Mehchia pyramidata, L. ! 



8. Callirrhoe p a 1 m a t a is what we have always taken for a small form of 

 C. involucrata, Gray, i. e. Malva involucrata, var. linearibola, Torr. and Gray. 

 Fl. Some of the specimens with narrow lobes to the leaves are exactly this 

 var. lineariloba (= Berlandier's No. 1815) ; the others are like Capt. Pope's 

 specimens from the Upper Colorado. It appears to run into the ordinary C. 

 involucrata. (I think I have elsewhere stated that C. macrorhiza is probably 

 a form of the little-known C. alcceoides.) 



9. Sidalcea Atacosais Malvastrum pedatifidum, Gray, PI. Lindh. 2, p. 160, 

 and in the later collections. How, if "the specimens are in fruit only,' were 

 the peculiar characters of the genus Sidalcea ascertained ? 



10. Malvastrum linearifolium is Sida fasciculata, Torr. and Gray, a 

 most genuine Sida.
