DR. H. F. HANCE ON NORTH-CHINA PLANTS. 91 
Not before recorded from China proper, but found on the Lower 
Amur by Maximowiez. Dr. Williams's are undistinguishable 
from Japanese specimens. 
57. CHRYSOPOGON pictus, Hance (Ann. Sc. Nat. 5° sér. v. 252).—In 
collibus ditionis Pekinensis legit Dr. S. W. Williams. 
As remarked by me when describing this grass, it is naturally 
far more nearly allied to Andropogon montanus, Roxb., than to 
Chrysopogon gryllus, Trin., though it agrees technically with the 
latter in its spikes being reduced to the terminal articulation, by 
which character alone Mr. Bentham, in the ‘ Flora Hongkongensis,’ 
distinguishes Chrysopogon from the § Amphilophis of Andropogon. 
It is evident that a distinction which breaks through natural affini- 
ties and which, moreover, is not constant (for depauperated spikes 
occur in many Amphilophides), cannot be adhered to; and there 
appears no alternative than either, with Steudel, to merge Chryso- 
pogon in Andropogon, or, preferably, as it seems to me, to follow 
Prof. Grisebach, who, in his valuable paper * Ueber die Grami- 
neen Hochasiens, transfers the Amphilophides to Chrysopogon. 
Dr. Williams’s specimens agree well with De Grijs’s from Fokien 
province and with others since found near Canton. The prevail- 
ing constituents of the Grass-flora of Peking would not lead us 
to expect the occurrence of such a tropical form as this from that 
neighbourhood. 
58. Crypsis ACULEATA, Ait.—Peking, in arenosis, legit R. P. David. 
Omitted from Maximowicz’s * Index, nor has it been recorded 
from the neighbouring regions of the Asiatic continent, from Japan, 
or Sachalin, the interior of Siberia being the nearest known habitat. 
59. CALAMAGROSTIS BRACHYTRICHA, Steud.?—In collinis siccis et 
ad margines agrorum ditionis Pekinensis, æst. 1865 coll. Dr. S. W. 
Williams, 
I have seen no authentie specimens ; but mine agree perfectly 
with Steudel's character. The species has only, hitherto, been 
recorded from Japan. 
60. STIPA SIBIRICA,, Lam.—In paradiso imperiali prope Peking, necnon 
ad Ku peh kau, juxta magnum murum, Aug.-Sept. 1866 coll. Dr. S- 
W. Williams. 
Not previously recorded from Peking, where, however, the 
allied S. Bungeana, Trin., with beardless anther-cells, is found.
