[Our Chinese specimens have the glumes much less conspicuously muricated than in those from Dr. Wight, 

 collected in the Peninsula of India; but there is no other difference. Some of our plants from Dr. Wight 

 have the panicle 3 inches long. It is probable that both I. pulchella and I. miliacea of Roth are referrable 

 here, there descriptions being bad. P. patens, Roxb., seems likewise to be the same, judging from his draw- 

 ing in the East India Company's Museum, t. 803, notwithstanding that both in the description and figure 

 he has represented the upper floret as bisexual, an error he might have readily fallen into on the supposition 

 of its being a species of Panicum.']

[It is probable that the above description had been taken from a single imperfect specimen. We have, how- 

 ever, a more complete series before us; some, and indeed almost all the specimens, (except those in a young state,) 

 bear a closer resemblance to G. alopecurus, N. ab E. in Herb. Wight, (or G. cenchroides, Kunth, excluding
