Brazilian Orchids - Genero/Genera


Tribe:	Cymbidieae
Subtribe:	Oncidiniiae
Etymology:	From Greek = Onkos. Olof Swartz, in 1800, gave this name due to the small callus situated at the base of the lip which seams to be a wart, tumor, swelling, which in Greek is Onkos

Brazilian Species

Brazilian species by section, according to Sonderabdruck aus Schlechter, Die Orchideen, 3. auflage. Bd.1 and occurrence by states.
We list a greater number of species as, according to Brazilian researchers, other species which have not been considered in this work, would be also valid.
This list is not exhaustive. It does not include all Brazilian species assigned to the genus Oncidium but the great part of them.

The recent nomenclatorial changes proposed provoked the transference of some species to other genera however many of them are still known by their old nomenclature, it means, as Oncidium. As it happened with another transferred genera, there is no change in the registration of the hybrids because it would be impossible to change registers that have been doing since 100 years ago.
The formerly recognized Section Plurituberculata is now excluded from the genus and has been elevated to generic rank under the genus Lophiaris established by Raffinnesque in l838. This change has been based on morphologic characteristics and due to the fact that those species present in the index of chromosomes a clear divergence with the genus Oncidium (Karlheinz Senghas, , translated by Waldemar Scheliga in Orquidário, volume 12, nº4)

The formerly Section recognized asOncidium (or section Equitantia Lindl l850) has been excluded of this genus and has been elevated to generic rank under the genus, re-establishing the name of Tolumnia given by Rafinnesque in l836.
The formerly Section recognized as glanduligera has also been excluded from the genus Oncidium and subdivided into two other genus: Psychopsiella Lückel & Braem l982 and Psychopsis Rafin l838

Observation

(?) – to be confirmed.

01- barbaceniae 1. Lindl – Pabst considered as Section Oblongata and Garay & Stacy as Section Synsepala

02- Species contested by Senghas in his last work about Oncidium. Carlos Eduardo de Britto Pereira, (CEBP) agreeing with Pabst & Dungs e Garay & Stacy, believes that it is not the same species as Oncidium altissimum Sw. .

03- Garay & Stacy considered O. caldense as synonym of O. ramosum, CEBP agrees with Pabst & Dungs, he believes there are two valid species.

04- Species contested by some researches who are in doubt if it is a valid species or a synonym of O. hydrophilum

05- Garay & Stacy e Pabst & Dungs considered O. ottonis as synonym of O. concolor. To CEBP e Senghas, both species are valid.

06- CEBP suspects that O. fimbriatum and O. cornigerum could be the same species, may be different horticultural form.

07- CEBP considers very possible that O. cruciatum would be O. pubes.

08- To Carlos Eduardo, O. praetextum and O. gravesianum and what is called O. enderianum are the same species and Oncidium praetextum would be the valid name.

09- Pabst wrote O. enderanum. We do not know if he has some raison to do this or if it was just a type write mistake. However some researches such as Garay & Stacy, adopted this way of writing .

10- To Carlos Eduardo, O. euxanthinum and O. varicosum would be two different species.

11- O.ghillany possibly is a different species from O. spilopterum (see the interview)

12- Pabst considered O. mantini as a synonym of O. pectorale Carlos Eduardo considered both species as valid and O. duveeni as a synonym of O. mantini. Senghas considered O. duveniii as a valid species and did not mentioned mantini. O. mantini. According to Carlos Eduardo (agreeing with Rolfe) It can be a natural hybrid between O. forbesi and O. marshallianum.

13- O.pentescostele Rchb. f. – 13- O. pentescostele Rchb. f. - doubt species-possibly O. baueri

14- Carlos Eduardo considers O. montanum Barb. Rodr. and O. pirarense Rchb. F as two valid species. Pabst e Dungs as well as Garay & Stacy considered O. montanum as a synonym of O. pirarense

15- O. psyche Schltr – Garay and Stacy considered as synonym of O. micropogon. Pabst & Dungs considered as two different species.

16- Pabst & Dungs wrote O. rivieranum, Senghas and Garay & Stacy as O. riviereanum.

17- O.spilopterum Lindl - To Senghas e Garay & Stacy, is section Synsepala

18- X litum Rchb. f. – Senghas considered as species dubia.

19- Pabst & Dungs e Garay & Stacy considered O. pollettianum as synonym of O. gardneri however Carlos Eduardo de Britto Pereira considered as a valid species.

20- Pabst & Dungs e Garay & Stacy considered O. praestans as synonym of O. gardneri.
