Apostasia ramifera S. C. Chen & K. Y. Lang 1986 is a Chinese endemic and endangered orchid. Here, we report the complete chloroplast (cp) genome sequence and the cp genome features of A. ramifera. The cp genome was 157,518 bp in length with a typical quadripartite structure, which was comprised of one large single-copy region (LSC, 86,353 bp) and one small single-copy region (SSC, 16,445 bp) separated by two inverted repeat regions (IRs, 27,360 bp). The cp genome encoded 133 genes, which included 87 protein-coding genes, 38 tRNAs and eight rRNAs. The average GC content of the genome is 35.8%. The phylogenetic analysis showed that A. ramifera was sister with A. wallichii and then nested in the other Apostasia species.

Geodorum eulophioides Schltr., is a critically Endangered orchid (IUCN). In this study, we report the first complete chloroplast (cp) genome of G. eulophioides to provide the underlying information for genetic breeding and conservation studies of this species. The cp genome sequence of G. eulophioides is 149,466 bp in length, which contains one large single-copy region (LSC, 85,436 bp), one small single-copy region (SSC, 14,086 bp), and two inverted repeat regions (IRs, 24,972 bp). The cp genome encoded 177 genes, of which 106 were unique genes (78 protein-coding genes, 24 tRNAs, and 4 rRNAs). Phylogenetic analysis showed that G. eulophioides is closely related to the genera Eulophia.

A new orchid species, Cheirostylis wenshanensis (Orchidaceae; Cranichideae; Goodyerinae), from Yunnan Province, China, is described and illustrated based on morphological. This new species is similar to C. pingbianensis, but it differs by having a leaf-like flora bract at bottom, to 2.3 cm long; Inflorescence raceme with 5 flowers; The rest part of lateral sepal 2.8–3 mm, front of lip 5–6 × 5–6 mm, both with 1 pale green spot at base of lip lobes, without denticulate between lobes.
