Comparison of Seed Morphology and Seed Coat Chemistry in (Orchidaceae) Species.

Orchidaceae is the largest flowering plant family in the world and holds significant importance in terms of biological diversity. Many of the species are found in endemic regions, serving as important indicators for the conservation of biological diversity. Therefore, research on the morphology, seed and embryo structures, chemical composition, and taxonomy of orchids is crucial for species conservation, habitat restoration, and the sustainability of natural habitats.

2-Amino-4-nitro-phenol-1-(2,4,6-trihy-droxy-phen-yl)ethanone (1/1).

In the title compound, C(6)H(6)N(2)O(3)·C(8)H(8)O(4), the 2-amino-4-nitro-phenol (ANP) and 1-(2,4,6-trihy-droxy-phen-yl)ethanone (THA) mol-ecules are both nearly planar, with r.m.s.
