03AB9E7CDE47192CFF74FF5AFAB9560E.taxon	description	Description: — Herbs up to 14 cm tall. Underground part represented by creeping vermiform roots. Flowers terminal and solitary or in terminal few-flowered monochasial inflorescence (more precisely, a thyrsoid with a single cyme), surrounded by involucre of usually 3 bracts (sometimes 2 bracts in lateral flowers), actinomorphic. Flowers usually coloured with white combined with dark to blackish blue / brown / green, with orange stamen appendages and sometimes certain other flower parts. Hypanthium inner surface without transverse bars, sometimes foveolate (described as “ fenestrated ” by Nuraliev et al. 2020, 2021) or irregularly reticulate. Annulus usually dome-shaped to erect, fleshy. Outer tepals present, distinct (never vanishingly small), unappendaged. Inner tepals postgenitally fused into a fleshy mitre, unappendaged or with small protuberance-like appendages up to ca. 1.5 mm high at mitre top (appressed to each other to form an apical mucro); mitre without foveae or with three foveae on upper surface. Mitre with valvate tepal aestivation. Stamens laminar, with long supraconnectives, fused postgenitally into a stamen tube. Supraconnective with adaxial skirt-like or wing-like appendage, with rounded or emarginate apex usually bearing several (up to 10) papillae. Interstaminal glands present (unverified for T. aurantiaca). Thecae surrounded by rows of glandular hairs. Placentas parietal, becoming column-like by detachment from ovary wall (unverified for T. aurantiaca); stylar column bearing 3 free styles; styles upright, usually rectangular. At fruit maturation, hypanthium abscising circumscissily. Fruit cup-shaped (a pyxidium), dehiscing apically by withering; pedicel sometimes moderately elongating during fruit maturation.	en	Nuraliev, Maxim S., Sennikov, Alexander N.

03AB9E7CDE47192CFF74FF5AFAB9560E.taxon	etymology	Etymology: — The name of the section is a plural form of the epithet of its type species, T. mirabilis. Thismia mirabilis is the first species of the section that has become known to science. Notes: — The description follows the terminology suggested by Nuraliev et al. (2021), along with their findings on morphology of one of the species belonging to this section, T. mucronata. Several species of Thismia sect. Mirabiles were observed to perform an unusual change of flower coloration immediately after immersion of the plants into alcohol: all the dark parts of the flower become intensively orange to red (Larsen 1965, Nuraliev et al. 2014, Phonepaseuth et al. 2024). Here we provide for the first time an illustration of this phenomenon (Fig. 1). This feature likely indicates the presence of a remarkable biochemical character in Thismiaceae. It has never been reported for any other representatives of the family, and its occurrence throughout Thismiaceae is still to be explored. The available images suggest a similar colour change in T. bryndonei Tsukaya, Suetsugu & Suleiman (2017: 135, Fig. 1 E – G).	en	Nuraliev, Maxim S., Sennikov, Alexander N.

03AB9E7CDE46192AFF74F8DBFC5956CF.taxon	distribution	Distribution: — India (Andaman and Nicobar Islands Union Territory). Notes: — Thismia aurantiaca differs remarkably from the other members of Thismia sect. Mirabiles in the flower coloration. While the flowers of the other seven species are coloured with white combined with bluish / brownish / greenish black, T. aurantiaca has white with orange (to light brown) flowers, lacking any blackish hues. Furthermore, the annulus of T. aurantiaca is unusually short (ring-like, in contrast to the dome-shaped to vertically elongate one in the other species). The sectional placement of T. aurantiaca remains therefore somewhat tentative, and is to be verified through the inclusion of the species into molecular phylogenetic analyses.	en	Nuraliev, Maxim S., Sennikov, Alexander N.
