Kimnachia
Kimnachia in Phytotaxa 327(1): 30. 2017 sec. Korotkova & al. 2017
- Type: Kimnachia ramulosa
Taxon standing
Category A. The genus is monophyletic based on a complete or very comprehensive phylogenetic study, and a phylogeny-based taxonomic synopsis was published.A
Notes
Phylogenetics: In their phylogenetic study of the Hylocereeae, Korotkova et al. (2017) found Pseudorhipsalis ramulosa outside the Pseudorhipsalis clade with high confidence and have therefore proposed to establish a new monotypic genus Kimnachia for P. ramulosa.B
Diagnosis
Plants shrubby with pendent stems, stems dimorphic, differentiated into primary and secondary stems, primary stems terete, secondary stems flattened and broadened in the apical part, margins of flattened stem segments crenate or obtusely serrate, stems often suffused purple, especially when exposed to sunlight. Areoles inconspicuous, lacking spines. Flowers actinomorphic, 1–2 per areole, small (ca. 10–15 mm in diameter), pericarpel with small scales, floral tube inconspicuous, ca. 2–4 mm long, green to reddish brown, perianth whitish/yellowish, fruit globose, whitish.
