Description:
Stems branched, more or less developed, slightly compressed, 8-10 mm wide. Leaves loriform (14- 8 x 1.6-2 cm), thick, rigid and coriaceous. inflorescence shorter than the leaves, simple or with 2-3 distant branches: peduncle thick, short ((1-4 cm), bearing 2-3 very short sheaths (2 mm) in the form of an embracing cupule; densely 6-15 flowered; rachis thick; bracts very short; flowers thick, 15 mm long (ovary included). Sepals 8-10 mm long, oblong, obtuse, attenuate. Petals smaller, oblique, lateral lobes of the labellum unobtrusive, median lobe 3 times larger, acute and curved in front; base densely villous and provided with 3 calluses, the median of which is much more projecting and elongated to the spur: spur short, saccate-obconnical (2 x 2 mm), bristly inside. Ovary 6-7 mm long. Capsule sessile, subcylindrical (30-50 x 7-10 mm), with 6 slightly projecting ribs.
Habitat:
It grows on trunks and main branches of trees or on rocks below them in deciduous woods usually in arid, hot, low-lying areas or in riverine forests or in coastal bush country to elevations of sea level to 1000 meters.
Flower time:
Flowering almost all year.
Cultivation:
Acampe pachyglossa is not difficult to grow. It is best to mounted the plant without substrate, the roots can develop freely on cork or larger, possibly cracked. Stand in the bright and warmest part of the tempered house. The necessary longer dry season corresponds to the long winter at some attitudes. From spring to the later summer, water frequently - regular spraying. If you do not need to reduce the watering during the relative rest period completely but limit itself with spraying so far that the leaves are not too strong shrink. Slight wilting symptoms do not hurt - may even be an indicator for next year's flowering - with the onset of growth in spring this apparent decline in vitality quickly compensated. While in nature despite fixed dry periods no developmental and arrhythmia is noted falls. The flowering time in local culture mostly in the summer months. When the inflorescence approach, usually in the spring, then it takes about 3 months to get up open the flowers.
Unfortunately, this species, in contrast to Acampe praemorsa, shows only one low branching tendency, which reduces the possibility of their vegetative propagation. Side shoots should be divided for the purpose of division only when their leaves almost the length of those at the main drive have reached. Fertilizers are unnecessary. Increased fertilizers show the same phenomenon as too warm and permanently moist culture: The leaves lose their roughness and firmness but will at the same time more susceptible to pests, and also affects such a culture the willingness to flower. Self-immolations are possible and lead to fertile seeds.
Notes:
Acampe pachyglossa is close to, and may be conspecific with, Acampe praemorsa (Roxb.) Blatt. & McCann, a native of India and Sri Lanka.
Distribution:
S. Somalia to S. Africa, W. Indian Ocean

Acampe Lindley Fol. Orch. Acampe. 1. 1853.
Synonyms:
Sarcanthus Lindl., Bot. Reg. 10: t. 817 (1824).
Description:
Plants epiphytic or lithophytic, monopodial. Stem simple or branched, stout, leafy. Leaves distichous, conduplicate, coriaceous, apex emarginate or 2-lobed. Inflorescence axillary, stout, racemose, corymbose, or paniculate; floral bracts inconspicuous, scale-like, persistent. Flowers non-resupinate, small, fleshy,fragile. Sepals and petals similar, flat to curved; lateral sepals adnate to the spur (when present). Lip saccate or with a short spur, adnate to the column, immobile, rigid, variously lobed, fleshy, papillose,tuberculate or warty, sometimes dentate; spur lacking any internal tongue or median septum. Column short, fleshy, glabrous or papillose; stelidia 2, tooth-like; foot absent; anther ovate, apiculate; pollinia 4, globose, united in 2 pairs; caudicle thick, linear; viscidium small, oval; stigma transverse, concave; rostellum short, emarginate.
Notes:
The genus Acampe was proposed in 1853 by John Lindley in his Folia Orchidacea. Although Garay (1972) pointed out that Lindley's earlier name Sarcanthus (Lindl. 1824, non 1826, typified by Epidendrum praemorsum Roxb.) had priority, the name Acampe has now been conserved. The complex and confusing history of this genus has been reviewed by Seidenfaden (1977C).
Type: non desianatus.
Etymology:
From the Greek acamptos (stiff) in reference to the brittle flowers.
Distribution:
The genus comprises about 10 (possibly fewer) species distributed in SE Asia, tropical and subtropical Africa, Madagascar and the islands of the western Indian Ocean.
Cultivation:
Easily maintained in cultivation provided the plants are kept in a warm and humid environment and in bright light. They can be grown in a pot or basket with open, free-draining compost, or mounted on a piece of hardwood or cork oak bark.
