 Thysanachne scoparia Presl, Rel. Haenk. 253. 1830. 

 Wright 3478. 



The Grisebach specimen is from eastern Cuba in L860 and numbered "1 13=3478." 

 Wright's 3478 in the Gray Herbarium is from San Juan de Buenavista, Nov. 21. 

 These were compared with the type of Nees at Munich and that of Trinius at Si. 

 Petersburg (from Martinique, Sieber 262). This species has an elongated dense panicle 

 more or less folded blades, the bent awn twisted below. It ranges from Cuba and 

 Mexico to Brazil, and is represented in the National Herbarium by the following: 

 Porto Rico: Heller 934, 4355, 6256; Sintenis 361, 5797; Barrett 101. Santo Domii

Thysanachne scoparia Presl was published in the Symbolae Botanicae, the title 

 page date of which is 1832 and which, hence, is later than the Reliquiae Haenkeanae. 

 But the part containing the above species must have been published earlier, for in 

 the latter work" is cited "T. scoparia. Presl de thysanachne, 1829. cum icone." 

 There appears to be no such work by Presl except the portion of the Symbolae (paiies 

 11 and 12 and pi. 6) where Thysanachne and T. scoparia are described as if they were 

 there originally published. The species is based on Sieber 264 from Martinique. 

 Presl's type from Mexico was examined at Prague. 



Pilgerb refers the Porto Rico species to A. hispida (Willd.) Kuntze (Andropogon 

 hispidus Willd.), to which he also refers A. brasiliensis Raddi. I have not seen the 

 type of either of the last two species, but in Trinius's herbarium is the type of Gold- 

 baehia mikani Trin., which is included by Pilger in the list of synonyms of J. hispida. 

 This I consider distinct from A. pallida, as did Nees, c and it is what I take to be 

 A. brasiliensis Raddi. This is also the A. brasiliensis of Hackel in Martius's Flora Bra- 

 siliensis, as indicated by plate 38 and by specimens so named received from Professor 

 Hackel. The spikelets are smaller and the awn shorter, sometimes scarcely exserted. 

 This species is represented in the National Herbarium by the following: Mexico: 

 Liebmann622, 635. Colombia: Pittier 1527. British Guiana: Mount Roraima Exped. 

 254. Brazil: Glaziou 17921, 20567 a; Henschen in 1868, Dusen 3875. Uruguay: 

 Arechavaleta.

Sheaths and blades pilose, the latter narrow and more or less folded, usually less 

 than 0.5 cm. wide; panicle rather loose, not elongated as in .1. martinicensis; awn 

 slender and bowed back like a shepherd's crook, but no1 twisted. The type of 

 A. cubensis from eastern Cuba, no. 1552 in 1859, is in the Grisebach Herbarium. 

 Another specimen also from eastern Cuba, 1860, is numbered ''115=1552." 



The types above cited, namely, those of Tresl at Prague, Grisebach al Gottingen, 

 and Trinius at St. Petersburg, agree with each oilier and are well characterized by 

 the shape of the awn. Additional specimens in the National Herbarium an- as fol-
