Item type:Publication, Specialization for Tachinid fly pollination in the phenologically divergent varieties of the orchid Neotinea ustulata(Frontiers Media S.A., 2021-06-16)Despite increased focus on elucidating the various reproductive strategies employed by orchids, we still have only a rather limited understanding of deceptive pollination systems that are not bee- or wasp-mediated. In Europe, the orchid Neotinea ustulata has been known to consist of two phenologically divergent varieties, neither of which provide rewards to its pollinators. However, detailed studies of their reproductive biology have been lacking. Our study aimed to characterize and understand the floral traits (i.e., morphology, color, and scent chemistry) and reproductive biology of N. ustulata. We found that the two varieties differ in all their floral traits; furthermore, while Neotinea ustulata var. ustulata appears to be pollinated by both bees (e.g., Anthophora, Bombus) and flies (e.g., Dilophus, Tachina), var. aestivalis is pollinated almost entirely by flies (i.e., Nowickia, Tachina). Tachinids were also found to be much more effective than bees in removing pollinaria, and we show experimentally that they use the characteristic dark inflorescence top as a cue for approaching inflorescences. Our results thus suggest that while both N. ustulata varieties rely on tachinids for pollination, they differ in their degree of specialization. Further studies are, however, needed to fully understand the reproductive strategy of N. ustulata varieties. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A new species of Telipogon (Orchidaceae: Oncidiinae) from the eastern Andes of Ecuador(Magnolia Press, 2021-08-09)N/A - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A new species of Telipogon (Oncidiinae) from Bolivia(Jardin Botanico Lankester, 2024-01-01)Telipogon minutus, from the Carrasco National Park in the Bolivian Yungas, is proposed as a ne species. Plants of T. minutus, which reach up to 4 cm in height, are the smallest known Bolivian Telipogon. The new species is characterized by its oblong to ovate labellum, which is weakly sub-auriculate and retuse at the base, with a semi-circular stigma, a column with two lateral lobes and a mammillary protuberance at the apex, and two tufts of setae with trifurcate apices. A description, figures, and a distributional map of the new taxon are provided, along with a discussion of the differences between the new species and morphologically similar Telipogon species. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Telipogon cruentilabrum (Orchidaceae: Oncidiinae): a new species from mid-western Ecuador, long misidentified as T. dendriticus(Magnolia Press, 2025)Telipogon cruentilabrum, from the cloud montane forest of mid-western Ecuador, is proposed as a new species. Plants of T. cruentilabrum are characterized by the yellow flowers with dark yellow longitudinal veins and tortuous, occasionally branched transversal lines; petals and lip with heavily undulate blades and irregularly reflexed margins; petals with a dark red-brown, swollen base; lip with a conspicuous radial, red-purple basal stain; a large, dark purple-red, elevated callus; anther profusely surrounded by three tufts of red-purple setae; and the stigma wide, sub-trapezoid, dark purple. This species has long been misidentified as T. dendriticus. Although in the holotype no callus is observed on the lip, and in its description and subsequent citations a callus is never mentioned. We provide here a detailed description, figures, distributional map and comparison with its morphological most similar species, T. tamboensis, and also include arguments to discriminate it from T. dendriticus.3
