Gymnocalyciinae
''Gymnocalycium'', commonly called chin cactus, is a genus of about 70 South American species of cactus. The genus name ''Gymnocalycium'' (from Greek, "naked calyx") refers to the flower buds bearing no hair or spines. In a 2023 classification of the tribe Cereeae, it was placed as the only genus in the subtribe Gymnocalyciinae, having formerly been placed in the subtribe Rebutiinae. Description The species of the genus ''Gymnocalycium'' are low-growing, usually solitary or sometimes small cushion-forming plants with globose, depressed-globular to short-cylindrical stems. The 4 to 15 (rarely more) ribs are usually broadly rounded, often sinuous, occasionally warty, and often have a "chin" just below the areoles. The thorns are very variable. The diurnal, funnel- or bell-shaped flowers appear at or near the apex. They are white or pink, sometimes yellow or bright red. The flower cup and the corolla are covered with a few large, broad and obtuse scales that have membranous edges. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cereeae
Cereeae is a tribe of cacti belonging to the subfamily Cactoideae containing about 50 genera, divided in 2023 among six subtribes. Description Cereeae are tree-like or shrubby, sometimes climbing plants. Their mostly elongated to spherical, ribbed and thorny shoots are not articulated. The flowers, which usually appear on the side of the shoot, open during the day or at night. Their pericarpels usually have a few scales or are completely glabrous. The fleshy, berry-like, bursting or non-bursting fruits often have a blackening adherent flower remnant. The small to large seeds are oval. The hilum and micropyle of the seeds are fused, one appendage is absent. Taxonomy Phylogeny In classifications before the use of molecular phylogenetic methods, Cereeae was one of nine tribes into which the subfamily Cactoideae was divided. Molecular studies found that these traditional tribes were not monophyletic. A broader circumscription of Cereeae, including Browningieae and Trichocereeae and ...
