Carex dolichostachya


Asia-Tropical: Philippines (Philippines present), Bontoc present, Japan present, Kalinga present, Luzon present, Rizal present, Ryu Kyu Is present, Southern America: Argentina Northeast (Formosa present)
Japan, Ryu Kyu Is., Formosa; in Malesia: Philippines (Luzon: Kalinga, Bontoc, Rizal).


The distinction between C. multifolia Ohwi, common in the montane regions of Japan, and C. dolichostachya Hayata, occurring from the Ryu Kyu Is. and Formosa to Luzon, is mainly made on account of the different colour of the basal leaf-sheaths. I have followed Koyama, who united the two as neither this character nor the other slight differences are constant.
, referred specimens from the Batan Is. (N. Luzon), mentioned above as C. ligata var. nexa Kuk. (non C. nexa Boott), to C. sociata Boott in . If this identity is true, C. sociata Boott would be the correct name for this species.
A specimen from Sarawak (Mt Murud, 2400 m, Nooteboom 2030) undoubtedly belongs to sect. Mitratae, possibly in the vicinity of C. dolichostachya. The utricles, however, are longer together with the nuts, and the leaves are smaller. — (Noot.).
