Chase — Notes on Genera of Paniceae. I. 187 



the previous publication by Linnaeus is cited, and also Brown Jam. 365, 

 and Sloane, 1 : 43. t. 14. f. 2. " Hab. in Jamaica." 



Brown (1. c.) after his polynomial cites Sloane t. 14. 



Sloane's figure (1. c.) is an excellent representation of the upper portion 

 of the plant, a leaf and overmature panicle. 



Panicum lanatum Rottb. 1776. Descr. PI. 3. Based on Andropogon insu- 

 lare L.; the same reference to Sloane is also given. Here follows the first 

 adequate description of the species, even the fruit being described : " Corol- 

 las valt'ie 2 lanceolate, concavse, acutissimse, membranaceEe." 



Milium villosum Sw. 1788. Prod. 24. Based on Andropogon insulare L. 



Beauvois 1812. Agros. 150, in the index refers Andropogon inmlaris to 

 Monachne, but this species is not mentioned under that genus on p. 49. 



Panicum leucophoeum H. B. K. 1815. Nov. Gen. et Sp. 1 : 97. Based on 

 Andropogon insulate L. This species and P. adscendens H. B. K., which is 

 Syntherisma sanguinalis or a close ally, are placed together under " 3) Spicis 

 verticillatis, fasciculatis aut paniculatis (Digitarige plurimse)." 



Panicum insulare Meyer. 1818. Prim. Fl. Esseq. 60. Based on Andropogon 

 insulare L. The " valves of the corolla " are given as coriaceous with mem- 

 branaceous margins. 



Acicarpa Raddi. 1823. Agros. Bras. 31. with one species A. sacchariflora 

 Raddi 1. c. t. 1. f. 4. This is given on the authority of Nees. We have not 

 seen the original publication. 



Trichachne Nees. 1829. Agros. Bras. 85. 



(a #pi£ capillus et axvv gluma.) 



Calyx bivalvis, subbiflorus, gluma inferiore minuta. Flosculus inferior 

 univalvis vel bivalvis hirsutus, neuter ; superior hermaphroditus, valvulis 

 membranaceis mucronatis Caryopsis flosculi valvulis membranaceis vestita 



* * * Infiorescentia : racemi elongati, simplices, unilaterales, verticil- 

 latim paniculati. Spiculae geminae ternaeve, altera brevius pedicellata. 



* * * Flosculus hermaphroditus * * * bivalvis, glaber, mem- 

 branaceus, valvulis lanceolatis in mucronum subulatum attenuatis ad 

 fructum persistentibus membranaceo-chartaceis caryopsin tegentibus neque 

 cum eadem induratis. * * * Differt a Panico praesertim gluma flosculi 

 hermaphroditi, * * * at minime crustaceo seu cartilagineo indurato 

 sed semper flexili. 



Acicarpa Raddi 1823. Agros. Bras. 31. t. 1. f. 4. is cited as synonym and 

 a note of explanation added that the name is expunged because of its 

 similarity to Acicarpha Juss. [1803]. Nees' first species is Trichachne insu- 

 laris (L.) Nees, based on Andropogon insulare L. Five other species are 

 included, T. sacchariflora (Raddi) Nees, and four new species from Brazil, 

 T. recalva, tenuis, vehdina, and ferrv gin ea, the last two of which Nees says 

 he saw in the Royal herbarium at Berlin. 



Grisebach (1864. Fl. Br. \V. I. 557) places Panicum insulare and P. sac- 

 charatum Buckl. in Tricholaena ; Stapf (1898, in Fl. Cap. 7 : 382) transfers 

 " Panicum leucophaea, Sw." to Digitaria, remarking, " the structure of the 

 spikelets is * * * as in Digitaria.'" Stapf probably means P. leuco- 

 phoeum H. B. K. , which is a typonym of A . insulare L. Swartz did not pub- 

 lish the name given by Stapf. Millspaugh and Chase (1903, Fl. Yucatan,
