Chase — Notes on Genera of Paniceae. I. 187 



the previous publication liy Linnaeus is cited, and also Brown Jam. :^(i5, 

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



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



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

 of the plant, a leaf and overmature panicle. 



Panicmn lanatum Rottb. 1776. Descr. PI. 3. Based on Avdrnpagmi hixu- 

 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- 

 la; valcx 2 lanceolataj, concavfe, acutissimse, membranacese." 



Milium viUosum Sw. 1788. Prod. 24. Based on Aiidropogon insulnre L. 



Beauvois 1812. Agros. 150, in the index refers Andropogon, iimidori!^ to 

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



Paiiicum leucophoenm H. B. K. 1815. Nov. Gen. et Sp. 1 : 97. Based on 

 Andropogon insulure 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 (Digitarife plurimfe)." 



Funicum insulare Meyer. 1818. Pjiin. Fl. Esseq. 60. Based on Andmpogon 

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

 branaceous margins. 



Acicarpn Raddi. 1823. Agros. Bras. 31. with one species A. saccharijiora 

 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.

Calyx bivalvis, subbifiorus, gluma inferiore minuta. Flosculus inferior 

 univalvis vel bivalvis hirsutus, neuter; superior hermaphroditus, valvulis 

 membranaceis mucronatis Caryopsis fiosculi 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 fiosculi 

 hermaphroditi, * * * at minime crustaceo sen 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. saccharijiora (Raddi) Nees, and four new species from Brazil, 

 T. recalva, tenuis, vehdina, and frrrv given, the last two of which Nees says 

 he saw in the Royal herbarium at Berlin. 



Grisebach (1864. Fl. P,r. W. I. 557) places hmicum imulare and P. sac- 

 charadnn Buckl. in Tricholaevn ; Stapf (1898, in Fl. Cap. 7 : 382) transfers 

 " Pan i cum leucnphaen Sw." to Digitaria, remarking, " the structure of the 

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

 phoeum H. B. K., which is atyponym of A. insula re L. Swartzdid not pub-
