Latouria Dendrobiums

P. J. Cribb’s November 1982 treatment of the Latouria section of Dendrobium genus in “A revision of Dendrobium sect. Latouria (Orchidaceae)” considered forty-eight species of Dendrobium sect. Latouria. Various authors recognise between forty-eight and seventy-eight species in the Latouria section of Dendrobium. The species and varieties of the Dendrobium macrophyllum complex remain the subject of on going taxonomic studies and articles.

The Dendrobium sect. Latouria species could include (but may not be limited to) the following (in alphabetical order):

Dendrobium aberrans	Dendrobium acutisepalum	Dendrobium alexandrae
Dendrobium amphigenyum	Dendrobium armeniacum	Dendrobium atroviolaceum
Dendrobium bifalce	Dendrobium biloculare	Dendrobium convolutum
Dendrobium crassilobium	Dendrobium cruttwellii	Dendrobium curvimentum
Dendrobium dendrocolloides	Dendrobium diceras	Dendrobium engae
Dendrobium euryanthum	Dendrobium eximium	Dendrobium finisterrae
Dendrobium forbesii	Dendrobium hodgkinsonii	Dendrobium informe
Dendrobium johnsoniae	Dendrobium kauldorumii	Dendrobium laurensii
Dendrobium leucohybos	Dendrobium macrophyllum	Dendrobium mayandyi
Dendrobium mooreanum	Dendrobium normanbyense	Dendrobium otaguroanum
Dendrobium pachystele	Dendrobium pleurodes	Dendrobium polysema
Dendrobium psyche	Dendrobium punamense	Dendrobium rariflorum
Dendrobium rhodostictum	Dendrobium rhomboglossum	Dendrobium rigidifolium
Dendrobium ruginosum	Dendrobium ruttenii	Dendrobium setigerum
Dendrobium shiraishii	Dendrobium simplex	Dendrobium spectabile
Dendrobium subquadratum	Dendrobium tapiniense	Dendrobium terrestre
Dendrobium torricellense	Dendrobium uncipes	Dendrobium verrucosa
Dendrobium violascens	Dendrobium wisselense	Dendrobium woodsii

Of the above species three are not natural to the Australasian Native Orchid Society accepted region. These being Dendrobium laurensii (Moluccas, Halmaheira only), Dendrobium setigerum ( Philippines : Luzon only) and Dendrobium violascens (Moluccass, Ternate only).

Forty-five of these species grow on the island of New Guinea from sea level to the montane forests. Most are epiphytes but some (especially those from the montane forests) are terrestrials growing on Sphagnum and in marshy ground. The majority of species in cultivation or used in hybridizing grow from sea level to 1950 m and usually from areas of year-round rainfall.

The following twenty-four species have currently been included in the parentage of hybrids:

Dendrobium aberrans	Dendrobium alexandrae	Dendrobium amphigenyum
Dendrobium atroviolaceum	Dendrobium bifalce	Dendrobium convolutum
Dendrobium cruttwellii	Dendrobium engae	Dendrobium eximium
Dendrobium finisterrae	Dendrobium forbesii	Dendrobium johnsoniae
Dendrobium kauldorumii	Dendrobium macrophyllum	Dendrobium mayandyi
Dendrobium otaguroanum	Dendrobium polysema	Dendrobium punamense
Dendrobium rhodostictum	Dendrobium rigidifolium	Dendrobium shiraishii
Dendrobium spectabile	Dendrobium tapiniense	Dendrobium terrestre

The following four of these species have only been utilised for intersectional hybridising (not with other members of Dendrobium sect. Latouria):

Dendrobium amphigenyum	Dendrobium kauldorumii
Dendrobium mayandyi	Dendrobium otaguroanum
