Carex alopecuroides var. chlorostachys
Content
Description
Leaves subbasal and 1 higher on the stem, shorter to much longer than the stem, flat, stiffish, long-acuminate, scabrid on the margins and often asperous on the upper surface, 2-10 mm wide.

Nepal, Sikkim, and Khasia to Central and S. China, Korea, Japan, Ryu Kyu Is., Formosa, Tonkin and Annam, and Malesia: Sumatra (Atjeh; W. Coast: Mt Kerintji), Java (Mt Wajang in W., Mt Tengger: Ranu Regulo in E.), Central Celebes (Mt Kambuno), Philippines (Luzon), and New Guinea.
Notes
The only collection known from Celebes (Eyma 1395) was distinguished as C. doniana var. cacuminis Nelmes, which has no taxonomic value; the dwarfish habit has apparently been caused by continuous grazing of anoas, the small wild buffalo of Celebes, Bos (Bubalus) depressicornis.
Both C. alopecuroides and its var. chlorostachys are treated as varieties of C. japonica Thunb. by Kukenthal, and also recently by Koyama, but C. japonica seems to be distinct by its short- cylindric, not crowded, peduncled, usually pendulous spikelets, not distinctly awned glumes, and its very long stigmas. In typical C. alopecuroides the leaves are usually narrower than in var. chlorostachys, the spikelets very slender, and the utricles somewhat narrower, less inflated, but the two are very near to each other and connected by intermediates. C. subtransversa Clarke was described from N. Luzon, where also C. alopecuroides var. chlorostachys occurs. I fail to see differences between the two but for the narrower leaves of the former, which is said to differ also by the suberect — not patent — utricles; the specimens are not fully ripe and the degree of reflexion of the utricles depends upon maturity. Kukenthal placed C. subtransversa under C. brownii and its var. transversa (Boott) Kuk., with which it is certainly not closely related.
