Graminea.~\ CHINA. 



inferior apicem versus quadrinervis, apice bidentata, latere inflexa et in carina sursum ala membranacea praedita, 

 superior gluma autem in carina dorsali media. Gluma; spicule pedicellate: angustiores nee breviores, nee 

 versus apicem marginatae. 



[We fear that the difference between these varieties is not constant : we have observed on the same panicle 

 some glumes with four nerves, others where the middle pair had coalesced into one in the centre, and others 

 where the two lateral ones had merged into the margin ; so that the glumes might be said to be either 

 2-, S-, er 4-nerved : the smaller the specimen, the more decidedly were the glumes only 2-nerved.]

Spicule heterogamse, in fasciculos simplices aut bi-trifidos disposite. Quatuor verticillate, masculae vel 

 neutrae, sessiles vel brevipedicellate, in quarum centro una hemi-ologama hermaphrodita, sessilis vel subsessilis. 

 adjectis neutris masculisve geminis longius pedicellatis, saltemve earum pedicellis sterilibus, ex quo numerus 

 primarius septenarius singuli flosculi oritur ; ubi autem alter pedicellus hermaphrodite, adjectorum alteram fert 

 spiculam femineam neutris vel masculis geminis stipatam, novem numeramus in fascieulo spiculas, sc. neutras 

 masculasve 7, et hermaphroditas duas. In una specie spica adest simplex, dimera, ex duabus conjunctionibus 

 spicularum exstructa, quarum inferior spiculam unam exhibet fertilem sessilemquc setigeram, alteram neutram 

 aut masculam muticam, superior simili ratione vel unam vel Unas pedicellatas masculasque femineae urn 

 consociatas. Spicularum structura omnino Andropogonum e subgenera: Trachtjpogonis. Habitus Andropo- 

 gonum e subg. Cymbopogonis ; a qmbus Anthisliria non charactere spicularum, sed inRorcseentia distinguitur, 

 qnam si sensu latiori intelliges omnesque species, vaginata inflorescentia gaudentes, hoc solo charactere, 

 neglecta positione verticillari, Anthistiriarum communi nomine appellabis, natural! dispositione melius consules. 

 Constat fasciculus primitivus Anthistirim e ramulo paniculse bifido, cujus ramuli singuli, pro more, spiculam 

 hemiologamam hermaphroditam unam, cum binis incompletis sustinent. Abortientibus autem bin.s laterahbus 

 fertilibus, restat quadriga spicularum sterilium cum intermedio fertili binis sterilibus stipata. Ponas autem 

 singulam triadem, ut in fascieulo enneastachyo videmus, ab altero latere spiculam singulam stenlem ab a tero 

 autem fertilem cum suis sterilibus stipantibus proferre, et turn vero habebis spicam, abortu naturah in illam 

 tetrastachyam Andropogonis (Cymb.) nani abeuntem. Sunt igitur ejusmodi fasciculi revera spicaa tres digitate, 

 ad exilissimum partium numerum redactse ; aut, si omnes in spicam unam coalescere posse fingis, spicatnbus 

 aut quatuor paribus constans.

Ab A. villosa, Lam., differt statura minore et seta longa (1 J-l J poll.) Qua; sola comparanda, A. tortilis 

 Presl, spiculis in singulo fascieulo pluribus (14), et glumis glabris differt. Ab A. ciliata recedit glum.s 

 masculis longius acuminatis, pilis tuberculis parum conspicuis insectis, et fasciculis solitariis minonbus pluri- 

 floris. Valvula flosculi fertilis inferior lineari-angusta, in setam transiens, Anthistiri* ; fasciculi novemflon 

 et spicula; steriles biflorae (masc. aut neut.) Androscepice, ut itaquc medium tcneat inter genera ista hac species, 

 —Perobachne, Presl, (Anth. villosa. Lam.) Androscepia est seU brevissima instructa. Igitur tna ha;c 

 genera in unum rursus revocanda sunt.
