Orchidaceae

Belongs within: Petrosaviidae.Contains: Cypripedioideae, Monandrae. The Orchidaceae, orchids, are a diverse and distinctive group of plants in which the flowers commonly have the lower petal differentiated into a distinctive lip. Pollination often involves complex specialisations, attracting pollinators using visual and/or odour cues rather than by offering a nectar reward. Most studies agree that the Indo-Australian… Continue reading Orchidaceae

Cypripedioideae

Belongs within: Orchidaceae. The Cypripedioideae, slipper orchids, are a group of orchids distinguished by flowers bearing a slipper-shaped labellum, as well as loss of the dorsal median stamen, type III–IV endothecial thickenings, and a smooth pollen tectum (Freudenstein & Rasmussen 1999). A slipper of the lip Published 7 March 2019 The world of flowering plants… Continue reading Cypripedioideae

Orchidinae

Belongs within: Orchidoideae. The Orchidinae are a group of terrestrial orchids found primarily in the Northern Hemisphere, particularly around the Mediterranean and eastern Asia. Members include the bee orchids of the genus Ophrys whose flowers mimic large Hymenoptera and attract males of the mimicked species to act as pollinators via pseudocopulation. Platanthera, the butterfly orchids… Continue reading Orchidinae

Caladenia

Belongs within: Orchidoideae. Caladenia is a genus of terrestrial orchids found primarily in Australia with outlying species in Malaysia, New Caledonia and New Zealand (Moore & Edgar 1970). Characters (from Moore & Edgar 1970): Plants terrestrial, with pilose or glandular hairs; tubers more or less globose, new ones produced more or less within leaf-sheaths. Leaf… Continue reading Caladenia

Orchidoideae

Belongs within: Monandrae.Contains: Caladenia, Cranichideae, Thelymitra, Acianthinae, Pterostylis, Diuridinae, Prasophyllinae, Orchidinae, Habenariinae. The Orchidoideae are a clade of terrestrial orchids united by spiral phyllotaxy, together with the presence of polygonal epidermal cells, and intercellular spaces in the testa (Freudenstein & Rasmussen 1999, as Orchidoideae + Spiranthoideae).

Spiranthinae

Belongs within: Cranichideae. The Spiranthinae are a mostly Neotropical group of terrestrial orchids, characterised by basal leaves, flowers with the margins of the labellum adherent to the sides of the column and pollinium tetrads differentiated into a body and stalk, and seeds with elevated transverse anticlinal cell walls and ridges on external periclinal walls (Salazar… Continue reading Spiranthinae

Cranichideae

Belongs within: Orchidoideae.Contains: Spiranthinae. The Cranichideae are a group of orchids characterised by the presence of specialised amyloplasts in the roots called spiranthosomes, together with distinguishable subsidiary cells in the leaf epidermis and type III/type IV thickenings in the anther endothecium (Freudenstein & Rasmussen 1999). <==Cranichideae [Spiranthoideae] | i. s.: Pachyplectron [Pachyplectroninae]A86 |–GomphichisRG07 `–+–+–AltensteiniaRG07 |… Continue reading Cranichideae

Thelymitra

Belongs within: Orchidoideae. Thelymitra, sun orchids, is a mostly Australasian genus of terrestrial orchids bearing regular flowers with petals similar to sepals. Characters (from Moore & Edgar 1970): Plants terrestrial, glabrous; tubers ovoid, new one produced at base of parent plant. Leaf solitary, sheathing at base, linear to lanceolate, often thick and fleshy; cauline bracts… Continue reading Thelymitra

Pterostylis

Belongs within: Orchidoideae. Pterostylis, the greenhood orchids, is an Australasian genus of terrestrial orchids in which the dorsal sepal is curved forwards to form a distinctive hood over the flower. Characters (from Moore & Edgar 1970): Plant terrestrial, usually glabrous; tubers ovoid to globose, produced close to or at some distance from parent plant. Leaves several,… Continue reading Pterostylis
