fultJB. Pedicellus altcrius spicula; elongatus cuni raclii glaber, v, 

 passim ad angulos ciliatus. Arista interdum conspicue exserta. 

 Ab hac planta distinguo alteram caule erecto, foliis angustioribus 

 basi minus aut haud obtusatis, rachibus pedicellisque frequcntius 

 I evidenter ciliatis, pedicellis brevioribus et bracteis apicem versus 

 paulisper herbaceis. Hi^c jjlanta regiones aboris remotas occupat * 

 e. g. ad flumina Macleay*s et Brisbane^s River, ad Rockhamptou 

 (Tliozet)j in Arnhemia boreali ; includit I. australe (R. Br. Pr. 

 205), Andropogon cryptatherus (Steud, Glum. i, 377), L triticeum 

 (R. Br. Pr. 205 ; Andropogoa triticiformis, Steud. Glum. i. 377) 

 etl. villosum (R. Br. Pr. 205, Andropogon villiferus, Steud. Glum. 

 i. 376). De horum relatione ad quosdam congeneres Indicos et ad 

 A. murinum (Steud. Glum. i. 377 ; Ischaimum murinum, G. Forst. 

 Prodr. p. 73) inquirere oportet. 



Andropogo7t Gryllus (Linne Spec. Plant. 1480 ; Holcus Gryllus, 

 R. Br. Prodr, 199 ; PoUinia Gryllus, Spreng. Pugill. ii. 10 ; Chry- 

 sopogon Gryllus, Trin. Fundara. 188 ; Parlatore Flor. Italian. i.

 lidus, R. Br. Pr. 199 ; Pollinia pallida, Schultes 3Iautiss. ii. 829) 

 statu normali multos locos Australiai tropicse et orientalis extratro- 

 pic^ inhabitat ; e..g. : ad Darling's River (Neilson), Rockhampton 

 (0'Shanesy), Armadilla (Barton), Peak-Downs (Lau), Barcoo 

 (Birch), Dogwood Creek (Bunce), Port Denison (Fitzalan), Rey- 

 noId's Rauge et Strangeway's River (J. Macd. Stuart), AIbert's 

 River (Landsborough), Abel Tasman*s et Victoria's River nec non 

 Sturt*s Creek et Hooker's Creek (F. M.), Rami paniculaj inter- 

 dum flores duos bisexuales gerunt, altero horum iterum stipitato v* 

 pedunculato, dum haud omnes flores masculi adstantes evolvuntur.

Ad hanc formam pertinet A. Zeylanicus (Steud. Glum. i. 397 

 non Arnott in Benth. Flor. Hongk. 423 ; Chrysopogon Zeylani- 

 eus, Thwaltes Enum, 366, Raphis Zeylanica, Nees in Steud. Glum. 

 1- c. Andropogon echinulatus, Steud. 1. c.) A. Wightianus, Steud. 

 1- c. tantum pedicellis florum lateralium barbatis ab A. Gryllo 

 difTert. 



Andropogon elongatus (Sprengel Syst, i. 287 ; Holcus elongatus, 

 R. Br. Prodr. 200) raihi a promontorio Cape York (Djemel), a 

 Sweer's Island (Henne) et a flumine Albert^s River (Landsborough) 

 notus est, ubi paludes circumdat. Gramen arundinaceum, ssepe 

 6-pedale. Panicul^e rami plurispiculati. Arista floris bisexualis 

 bracteis passim aliquoties longlor, sed semper pertenuis. A. mu- 

 ricatus (Retz. Observ. iii* 43) e definitione huic propinquus, sed 

 fide iconis cl. Pretre (in Beauv. Essai, pl. xxii. fig. 10) bracteis 

 masculis conspicius asperis jam distat. A. elongatus praacipue 

 florum dispositione ab A. Gryllo discrepat ; ambobus interstat 

 planta a fluvio Hunter*s River (Leichhardt), Rockhampton (0'Sha- 

 \ ^Gsy), Alberfs River (Henne), statura l^vitate et aristis A. Grylla 



conveniens, inflorescentia autem ad A. elongatum pertinens.
