DOUBTFUL AND EXCLUDED SPECIES. 



P. ABLUDENS, Eoem. fy Schult. St/st. ii. 457 ; Roth Nov. Sp. 53. P. ramosum, 

 Heyne mss. ex Roth I.e. P. paradoxum, RotU.,mss. ex Roem. Sf Sch. I.e., is 

 evidently a Paspalum. 



P. ACICULARE, Desv. in Poir. Encycl. Suppl. ii. 274 ; Nees Agrost. Bras. 235 ; 

 Kunth Enum. PI. i. 116 ; Steud. Syn. Gram. 82, is, I suspect, an American species, 

 erruneously described as E. Indian. There is no Indian Panieum at all answering 

 to it. 



P. ANG-TJSTATUM, Edffew. in Journ. Beng. As. Soc. xxi. (1852) 157 ; name only. 



P. ARANEOSUM, Edgew. in Index Kewensis, is an error for Pennisetun araneosum, 

 Edgew. (= Penn. lanugiuosum). 



P. COJSCINNUM, Edgew. I.e. 157, 179, 187; the description will apply to various 

 species. 



P. FESTUCOIDES, Poir. Encycl. Suppl, iv. 283 ; Kunth Enum. PI. i. 131 is un- 

 determinable. 



P. FLEXUOSUM, Retz. Obs. iii. 9, and iv. 16 ; Steud. Syn. Gram. 83, described as 

 an Indian Plant of Koenig's by Retz., is doubtfully referred to the Brasilian Isachne 

 ventricosa by Doell in Mart. Fl. Bras. ii. II, 274. Retz describes it as being like 

 capillare, Linn., but with the nodes bearded by reflexed hairs. 



P, FUGAX, Koen. in Naturf. xxiii. (1788) 209 ; Gmel. Syst. 162 ; Kunth I. c. 

 134, is undeterminable. Mr. Rendle informs me that this probably refers to a plant 

 alluded to by Koenig in his correspondence (now in the British Museum) as " a 

 decumbent Panieum growing in rice-fields, in which the panicle flowered almost 

 hefore it had left the sheath, often a larva is found in the flower when the latter 

 perishes otherwise it is caducous." A diseased Panieum (possibly P. psilapodium) 

 bearing the name P. insectiferum, Koen. mss. in Herb. Mus. Brit, is presumably 

 the plant. I find diseased spikelets to be frequent in P. psilopodium. 



P. HEYNIT, Roth Nov. Sp. 49 ; Kunth 1. c. 130 ; Steud. I. c. 80 ; branches of 

 oblong panicle strict divided, base hairy, lowest whorled with fascicled flexuous 

 scabrid branchlets, pedicels solitary alternate, gl. I cordate obtuse embracing the 

 spikelet, leaves sharply serrate, margins and mouth of sheath hairy. 



P. INFIDUM, Steud. Syn. Gram. 63, is probably a Paspalum. 



P. KUNTHII, Steud. Norn. Ed. II, ii. 258. P. orthum, Voigt Sort. Suburb. 

 Calcutt. 701 ; P. Pseudostricta, Steud. Syn. ''Gram. 39 ; Digitaria stricta, Both 

 Nov. Sp. 38; Setaria ? stricta, Kunth Revis. Gram. i. 47, Enum. PI. i. 157. I 

 have failed to identify this plant. It is possibly a Paspalum. 



P. KEPENS, Roxb. Ic. ined. t. Ill, 112, 796. Three plants of the section Bra- 

 chiaria thus named are in Roxburgh's collection of drawings, none of them answering 

 to his description of repens in Fl. Ind. (which I take to be P. vestitum), nor to the 

 P. repens, Linn. All are represented .as perfectly glabrous, with stem 12-18 in. 

 high, creeping below ; leaves flat, 4-5 in., strict, narrowed from a rounded base to 

 the top; panicle 4-6 in.; spikes 10-20, 1-l^in. ; spikelets subsessile, about f in., 

 close set, sometimes obscurely paired, green ; gl. I - III, 5-uerved. In t. Ill 

 the spikes are about 10, distichously spreading. In t. 112 there are about 20 dis-
