Hello colleagues! im actually revising some Peruvian Stelis (Orchidaceae) and I encounter with a confusing issue. Maybe someone here could help me. On his latest work, Luer described S. miranda a newly species from Colombia. His notes mention its resemble with three Bolivian species: S. antennata, S. saltatrix and S. ballatrix. Here comes the problem! I was unable to find any reference to the last two species mentioned. Apparently S. saltatrix or S. ballatrix non-exist either on Tropicos or IPNI. Does anyone know where this two species were published?
Thanks!!!
Can you please send the protologue of S. miranda Luer. What is the full generic name?
In IPNI the following species is given:
Orchidaceae Pleurothallis miranda Luer -- Phytologia 46(6): 369. 1980 (IK) but the generic name is Pleurothallis.
Stelis miranda Luer & R.Escobar, sp. nov. TYPE:
COLOMBIA: Norte de Santander: Páramo de Jurisdicciones,
3150 m, 30 April 1982, C. Luer, J. Luer & R. Escobar 7633
(Holotype: SEL). Fig. 25.
This very small, caespitose species is distinguished by
narrowly elliptical leaves; a long, filamentous peduncle
with a series long-pedunculate flowers; single-veined petals
abruptly contracted into slender tails; and an ovate, concave
lip with a basal callus that is bifurcated above the middle.
This unusual species is similar to three, small Bolivian
species distinguished by a filamentous peduncle and rachis,
and long-pedicellate flowers: Stelis antennata Garay, Stelis
ballatrix Luer & R.Vásquez and Stelis saltatrix Luer &
R.Vásquez. Stelis miranda differs from all of them by a
smaller habit with narrowly elliptical leaves, single-veined
petals abruptly contracted into filamentous tips, and a
concave lip with a bifid callus.
Kindly see page 208 in the PDF of the attached publication.
I think for the details of the two species you can contact the first author of the names:
Carlyle A. Luer
Also see this attachment. The two species likely be in this publication.
If you get the protologues kindly inform IPNI for inclusion in their database.
The Stelis of Bolivia review monograph is in press at the moment and will be published in Selbyana. You can check the illustrations and descriptions when it is published. Cheers
It is gratifying to know that you are working on native species little known in our country and I am pleasantly surprised that there are specialists like Dr. Luer who works in these orchids in the neotropic. Right now there is a monograph in progress. We can not discount the possibility of discovering new species. If there are subtle differences between these two species you could use molecular tools, such as there are cryptic species that could be solved through this tool and have more information to solve this issue.
good luck
