Content
Description
Leaves usually obovate-oblong to obovate-lanceolate, sometimes oblong to lanceolate, 4-25(-32) by 1.5—8(—11) cm, base long-cuneate to acute, apex acute to cuspidate, without domatia;
Flowers more or less crowded, usually in dense glomerules, sessile;
Sepals 5 (4).
Panicles lax to rather dense, 10-30 cm, branched up to the 2nd (3rd) order;
Distribution
Asia-Temperate: Taiwan (Taiwan present), Asia-Tropical: Laos (Laos present); Philippines (Philippines present), Continental SE. Asia present, Hué present, Japan present, Luzon present, Mountain Province present, Pescadores present, Ryu Kyu Islands present, S. Vietnam present
Widely distributed in continental SE. Asia, incl. China, Laos, S. Vietnam (only at Hué), Taiwan (incl. Pescadores), Ryu Kyu Islands, Japan; in Malesia: Philippines (Luzon: Mountain Province). .
Notes
subsp. rigida is variable in quite some characters in its area outside Luzon, for instance in the degree of pubescence, leaf shape, and dentation. In continental SE. Asia the area of subsp. rigida borders on or overlaps the areas of five or six other subspecies of M. simplicifolia, which substantially adds to the chance of confusing them, several specimens being hybrids. It is probable that these subspecies are ecologically isolated to a large extent and thus contact between them is prevented.
Quercus gilva var. procera BLUME, Mus. Bot. Lugd.-Bat. 1 (1850) 306, was included in the synonymy of M. rigida by HARA, l.c., but I found it to belong to Quercus gilva BLUME.
