HORT. MAL. VOL. XII. 67 



Tab. 49. Ischaemum muticum. Lin. 



50. Cyperus rotundus of Lin. 



Quoted by Roxburgh, and with a query by Rotboll, for C. procerus, but it an- 

 swers better to the C. hexastachyos of Rotboll, and to the figure and description 

 of Scheuchzer's, which Linnaeas has quoted for C. rotundus. By DennsUdt 

 it is referred to with a query for the C. Pangorei of Retz. 



51. Chloris barbata. Roxb. Andropogon barbatumof Lin. Mant. 



Lam. 



52. Kyllinga triceps. Rotboll. K. tricephala. St. Hil. Schcenus 



tuberosus. Burman. 



53. Kyllinga monocephala. Rotboll. Schcenus coloratus Var. 



Lin. 



In Sir W. Jones's copy this plate is marked Schcenus niveus, and it is quoted by 

 Poiret for the Linnean S. niveus; on the other hand, in General Hardwick's 

 copy, it is marked S.cephalotes of Lin. According to Muhlenberg, K. mono- 

 cephala has been found as far north as New Jersey, and he has also described 

 K. triceps to be a native of the United States, but they are both treated as 

 tropical plants in the stoves at Kew. 



54. Cyperus pygmseus of Vahl. Wight. Cyperus diffusus. Roxb. 



Cyperus mulenpulla. R. fy. S. 



Either as a Scirpus or a Fimbristylis it is misquoted by Rotboll, and most other 

 authors, for S.argenteus; but Poiret (Enc. Meth. Sup. v. p. 90) says that it is 

 not S. argenteus, but S. monander of Rotboll. It is the Cyperus musarius of 

 Hamilton's MS., who doubted whether Roxburgh's C. diffusus is the same 

 species. 



55. Cyperus ventricosus. R. Brown. 



Quoted erroneously by Rotboll for the Linnean C. Kgularis, and by Deonstedt 

 with a query for C.racemosus of Retz. 



56. Cyperus inundatus of Roxb. 



In all probability Linnaeus described a Chinese plant of Osbeck's, and, from 

 their general similarity, quoted the present figure and Plukenet's t. 191, fig. 7, 

 (which Plukenet himself had arranged separately), and then gave Rheede's 

 name, Ira, to the species. Roxburgh also has quoted both these figures, but 

 with a remark that Plukenet's answers best for his C. Iria ; and, as suggested 

 by Dr. Hamilton, this plant of Rheede's may probably be his C. inundatus. 



57. Andropogon Iwarancusa of Roxb. Ham. MS. A. schoenan- 



thus Var. Lam. 



A. Iwarancusa is supposed by Roxburgh to be the plant described by Sir Gilbert 

 Blane, with the name of Spikenard, in the Philosophical Transactions, vol. Ixxx., 

 and probably Sir Gilbert may have erred in saying that ' it is not to be met 

 with among the many hundreds of plants delineated in the Hortus Malabaricus.' 

 The Spikenard of the ancients is however shewn by two papers from Sir W. 

 Jones, and a third from Dr. Roxburgh, in the Asiatic Researches, to be one of 

 the Valerianeoo, i. e. Nardostachys Jatamansi of Don's Dictionary. 



58. Hypolytrum giganteum of Wallich. Wight. Schoenus 



nemorum. Vahl. 



This figure is quoted with a query by Rotboll for Fuirena umbellata, and Vahl of 

 S. nemorum says, 'A Schcenis differt calyce bivalvi intra squamam j a Ma-
