This proposed genus is readily recognizable by its solitary, erect spikelet, a 
character most unusual §n Gramineae. It was originally placed by me near the 
genus /’estuca, differing in a number of characters. Specimens were sent to Dr. 
E. Hackel, and he has favored me with the following opinion regarding the genus: 
“The floral structure of your Monostachya is near Festuca and Bromus, but is 
not identical with that of either genus. It comes still nearer to Schizachne, a 
genus recently described by me from the Island of Sachalin,” but differs from that 
genus in its flowering-glumes being only slightly notched and not 2-cleft at the 
apex, and in the short mucro emerging from between the teeth, not an arista 
emerging beneath the apical notch as in Schizachne. The habits of the two are 
quite different.” 
Doctor Hackel further calls attention to the fact that beneath the terminal 
spikelet on at least some of the culms are to be found one or two pedicels, 1 mm 
long or less, of abortive spikelets, from which he infers that the specimens do not 
show the normal state of the plant, but that it will really be found to have a 
few-flowered raceme when better developed plants are found, and that in this case 
the generic name I have selected will not be appropriate. The material I have 
had for examination has shown all stages of development of the spikelets from 
the flowers to mature seeds, and no culms were found with more than one spikelet 
developed. I have no doubt but that the form has been derived from some closely 
allied genus that normally, at least, has racemose, or compound panicles, but 
that the present plant is worthy of description as it stands.

In habit it closely approximates that of Centrolepis philippinensis Merr., from 
whence its specific name.

k Forming dense thickets between the upper border of the mossy forest and the 
| upper grass lands, here 1.5 to 2.5 m high, and scattered in the lower parts of the 
open grass lands, here much dwarfed, and frequently only a few centimeters high, 
C. M. Z. 16189, Merrill 6489 (both sterile), MeGregor 8893 (in flower). 
This species has previously been collected on Mount Ugo, and at Pauai, Ben- 
guet, and on Mount Halcon, Mindoro, but Mr. McGregor was the first to collect 
it in flower, thus making its accurate identification possible. The identifica- 
tion has been made by Mr. J. 8. Gamble, to whom specimens were sent, and to 
whom Doctor Hayata kindly sent fragments of the type for comparison. Otherwise 
known only from Mount Morrison, Formosa.
