Names published by Johann Friedrich 

 Theodor Bieler in his doctor's thesis entitled, 

 "Plantarum Novarum ex Herbario Sprenge- 

 lii Centuriam," issued May 30, 1807, were 

 entirely overlooked until discovered by Prof. 

 M. L. Fernald a few years ago. The names 

 that are based on specimens from North 

 America, mostly sent to Sprengel by Muhlen- 

 berg, were listed by Fernald in Rhodora 47: 

 198-204 (1945). Among them are seven 

 names of grasses. Bieler' s paper was repub- 

 lished unchanged by Sprengel under the 

 title, "Novarum Plantarum ex Herbario 

 Meo Centuria," in the second part of his 

 Mantiss Prima, pages 27-28 (1807), evi- 

 dently later than Bieler's paper. Bieler's 

 name is not mentioned, and the species have 

 been credited to Sprengel and are so listed in 

 the Index Kewensis. 



In this edition of the Manual of Grasses, 

 Bieler is given as author of these names, 

 valid and synonyms. They are found in 

 Festuca, Sphenopholis, Sporobolus, and Pani- 

 cum. One name listed by Fernald, "Panicum 

 pensylvanicum Bieler, Plant. Nov. Herb. 

 Spreng. Cent. 4. 1807," was published by 

 Sprengel in Natchrag. Bot. Gart. Halle 30 

 (1801), the description reworded in Bieler's 

 paper, but agreeing with the earlier descrip- 

 tion. This and Panicum discolor Bieler, ap- 

 parently belonging in subgenus Dichanthe- 

 lium, are given in Unidentified Names (p. 

 982). 



It is possible that Sprengel, who was work- 

 ing on grasses, may have written the de- 

 scriptions of the grasses in Bieler's paper. 

 The century includes many genera in differ- 



ent families, from many parts of the world, 

 as well as garden plants and a good many 

 ferns, mosses, and lichens. But since Bieler's 

 paper was published before Sprengel's Nova- 

 rum Plantarum, he is here accepted as 

 author. 



ADDENDA 



Page 821 : Transfer "Aristida pallens [Cav. 

 misapplied bv] Nutt., Gen. PI. 1: 57. 1818. 

 Fort Mandan, N. Dak. [Nuttall]" to page 

 821 and insert after (26) Aristida longiseta 

 Steud. 1855. A Pursh specimen from the 

 Lambert Herbarium, in the herbarium of the 

 Academy of Sciences, Philadelphia, named 

 "Aristida pallens Cav. ic. 468" and bearing 

 on the back of the sheet in Lambert's script 

 "Louisiana. Bradbury.," was recently ex- 

 amined through the kindness of Prof. J. A. 

 Ewan. It consists of a single flowering culm 

 of Aristida longiseta Steud. Many of Brad- 

 bury's collections on the Lewis and Clark 

 expedition are marked "Louisiana. Brad- 

 bury." only, "Louisiana" at that time being 

 applied to the trans-Mississippi region. It 

 had been assumed that the collection was 

 made by Nuttall. Nuttall had access to the 

 Pursh Herbarium, later purchased by Lam- 

 bert, Pursh's patron.
