TWO OF BUCKLEY NAMES TYPIFICATION GRASS AND MUHLENBERGIA TEXANA REVISITED: MONTICOLA (POACEAE) M. DORR LAURENCE PAUL PETERSON M. and J. Department Botany of NHB-166, S?nithsonian Institution DC Washington, 20360, U.S.A. INTRODUCTION Samuel B. Buckley (1862) based new species of grass on collections he made In Texas and also specimens that had been deposited in the herbaria of the Academy of Natural Sciences of Pliiladelphia (PH) and Elias Durand (now P- DU). Asa Gray (1862; see also Buckley 1870) took exception to Buckley's work on grasses and wrote a scathing review^ which clarified details pertinent to the typification of these names. In his review, Gray 862) noted that he had borrowed 1 ( the specimens that Buckley had used in preparing his paper and that he showed them to the agrostologist George Thurber. Details concerning Buckleys work habits and the specimens that he examined are complicated. Consequently, made Com- mistakes frequently are in selecting lectotypes for Buckley names. ments on the lectotypifications of two Buckley grass names are given below\ Muhlenbergia texana Buckley In a recent revision of the annual species oi Muhlenbergia Schreber (Poaceae), & Annable Peterson (1991) designated Wright 739 (US) the lectotype of as MO Muhlenbergia texana Buckley and they considered a duplicate at to be an isolectotype. Their choice, however, must be superseded. Fortunately, changing change name. the lectotype does not the application of this First, there no evidence that Buckley used Wright 739 material in describing is comments name was on this species. Gray's (1862) indicated that this based Academy material in the (PH), which presumably was collected by Buckley: No Muhlenbe^'gia Texana. specimens were communicated unc]er this name, but '^ name one given by Mr. Buckley to the Academy's herbarium under the oi'Agrostis BuckU harhatis, may, from the description, be the plant intended. This a form is diSporobolus ranmJosus/' now Secondly, Buckley did not have access to the Wright specimens that are in the U.S. National Herbarium (US).
