Cyrtopodium polyphyllum

[Bud]

According to the tag it’s a Cyrtopodium paranaense; but when I googled it:
IOSPE says it’s a:
Cyrtopodium polyphyllum
The genus Cyrtopodium comprises about 42 species distributed from southern Florida all the way to northern Argentina. Cyrtopodium polyphyllum occurs on rocks or in sandy soils, in resting vegetation along the Brazilian coast. It flowers during the wet season (small wonder when I started watering it liberally in the warmer months it started to bloom) its inflorescences produce a high number of supinate yellow flowers. Cyrtopodium polyphyllum offers no rewards to its pollinators, but mimics the yellow, reward-producing flowers of nearby growing Stigmaphyllon arenicola (oil) and Crotalaria vitellina (nectar) individuals. Several species of bee visit flowers of Cyrtopodium polyphyllum, but only two species of Centris (Centris tarsata and Centris labrosa) act as pollinators. I am not a bee but I have learned how to manually self pollinate it.
This orchid is also called the “cow’s horn” currently indoors at the centerpiece table but it will go back outside the fire escape for the duration of the summer.
