Bhutanthera alpina ( Hand.-Mazz. ) Renz , 2001

Herbs, terrestrial, small, slender to stout. Tubers subglobose to ovoid, fleshy, neck with a few filiform roots. Stem erect, short, covered with tubular sheaths and sheathing leaf bases, glabrous. Leaves 2 or more, subopposite or clustered toward apex of stem, ovate, elliptic, or lanceolate, base tapering into amplexicaul sheath. Inflorescence terminal, racemose, 1-20-flowered, glabrous. Flowers resupinate; ovary twisted, fusiform to obovoid. Sepals free, similar. Petals usually smaller than sepals; lip 3-lobed though lateral lobes sometimes reduced and obscure, spurred at base; spur conic to cylindric. Column short, stout; anther with distinct connective and 2 divergent locules; stigma 2-lobed, conjoined, pulvinate; rostellum with 2 distinct arms; pollinia 2, granular-farinaceous, sectile, each attached by a short caudicle to a small naked viscidium; rostellum relatively large.

Five species: all found in the alpine zone of the E Himalayas; one species in China.

Bhutanthera albomarginata (King & Pantling) Renz (Edinbugh J. Bot. 58: 101. 2001; Habenaria albomarginata King & Pantling, Ann. Roy. Bot. Gard. Calcutta 8: 322. 1898) has been noted from Xizang (Press et al., Annot. Checkl. Fl. Pl. Nepal, 217. 2000). However, the present authors found no relevant specimens and therefore could not substantiate the occurrence of this species in China.

Ascocentrum ampullaceum is an species in the genusAscocentrum.

Plant blooms from spring to summer with many 2.5 cm wide flowers.

Distribution

Plants are found growing on trees in the forest of central China, Assam India, Bangladesh, the Himalayas, Nepal, Bhutan, Sikkim, Andaman Islands, Myanmar, Thailand, Laos and Vietnam at elevations of 300 to 900 meters

Culture

Plants are best grown hanged in baskets and on mounted and require bright to full sunlight and intermediate to warm temperatures. If hunged the roots must be watered frequently. Slightly reduce watering in the winter. Plants should be grown in media that is well drained such as tree fern fibers (for small plants), several pieces of coarse fir bark, or sphagnum moss.

Arundina graminifolia

Arundina graminifolia (D.Don) Hochr.

The bamboo orchid, Arundina graminifolia, is a species of orchid and the sole accepted species of the genus Arundina. This tropicalAsiatic genus extends from India, Sri Lanka, Nepal, Thailand, Vietnam, the Ryukyu Islands, Malaysia, Singapore, China to Indonesia, thePhilippines and New Guinea. It has become naturalized in Réunion, Fiji, French Polynesia, Micronesia, the West Indies, Costa Rica,Panama and Hawaii.

Description

Arundina graminifolia is a terrestrial, perennial orchid with reedy stems, forming into large clumps growing to a height between 70 cm and 2 m.

The plaited linear leaves are oblong lanceolate, with a length of 9 to 19 cm and a width of 0.8 to 1.5 cm. The apex is acuminate. There are amplexicaul (clasping the stem) sheathing stipules.

Bamboo Orchid, Fraser's Hill, Malaysia

This orchid blooms in summer and autumn, showing rather open clusters of showy terminal flowers, ten at the most. They bloom in succession on the terminal racemes, which are 7 to 16 cm long. These flowers, 5 – 8 cm in diameter, are a rosy lilac and white disk with a purple lip. The bracts are wide triangular and surround the main stalk of the flower cluster. The occasional fertilized seed pods contain minute powdery seeds, and small plants often develop near the cane ends after flowering, and likely aid in propagation if allowed to reach the soil.

With only 200 of the plant to be recorded growing naturally in Singapore, the species is close to extinction there, largely caused by the destruction of its natural habitat, namely the rainforests and mangrove forests. The remaining plants, commonly called Tapah weeds, can be found in the secondary forests or at the forest fringes. It is however very common in road cuts and other disturbed areas in full sun in Sarawak, East Malaysia, where it often is the most common flowering plant to be seen along the roadsides.
