Diapensiaceae (Link) Lindley is a small family of flowering plants, classified as a crown group, which includes 15 species in 6 genera. [2] The genera include Berneuxia Decne. (1 species),[3] Diapensia L. (5 species)[4], Galax Sims (1 species),[3] Pyxidanthera Michx. (2 species)[5], Shortia Torr. & A.Gray (4 species)[6], and Schizocodon Siebold & Zucc. (2 species)[7]. Members of this family have little economic importance. However, some members are cultivated by florist. [8]

Taxonomy

Past literature classified Diapensiaceae as an old family. [9] The name Diapensia was given to Diapensia lapponica by Linnaeus, previously, it was the Greek name of Sanicle. [10][11] The family, including only Diapensia lapponica, was named by Heinrich Friedrich Link in 1829. [12] Regarding the interrelationships in Diapensiaceae, debate still remains regarding the recognition of Schizocodon, separate from Shortia. However, recent molecular studies support the split of the two genera. [13] Additionally, recognition of species within the genera has been debated. Within the genera Pyxidanthera, two species have previously been recognized. Recent morphology and molecular work found that the two species do not have different morphology and gene flow exists between them. [14]


Overtime, various relationship among Diapensiaceae and other angiosperm families have been proposed. Previously, it has been placed with the order Rosales [15], as well as in the Cornales.[16] Diapensiaceae was also placed in an order of its own in the Cronquist system and by Takhtajan. [17] Recent studies have placed Diapensiaceae as part of the Ericales clade, belonging to the “styracoids” (Diapensiaceae, Styracaceae, Symplocaceae).[18] It is estimated that Diapensiaceae diverged from Sytracaceae about 93 million years ago. [19] The family is thought to have originated in the Northern Hemisphere.[20]


Distribution

Diapensiaceae family members are mostly found in North America and Eastern Asia. [8]

Genera Distribution[21]
Berneuxia Tibet, southern China, and Burma
Diapensia Mostly mountains in southern Asia, Diapensia lapponica is circumboreal
Galax Eastern United States
Pyxidanthera Eastern United States
Shortia Eastern United States, China, and Taiwan
Schizocodon Japan

Characteristics

Diapensiaceae family members are mostly herbs or shrublets. Flowers have radial symmetry, are hypogynous, and have most parts arranged in 5. The ovary is made of three fused carpels. They have both ectotrophic and endotrophic mycorrhiza associations. [3]

Genera Life Form Leaf Shape Flowers
Berneuxia Perennial herb linear and petiolate Distinct scape
Diapensia Cushion-like shrublet linear and lanceolate to oblanceolate and sessile Solitary
Galax Perennial herb reniform to orbicular and petiolate Raceme
Pyxidanthera Cushion-like shrublet linear and lanceolate to oblanceolate and sessile Solitary
Shortia/Schizocodon Perennial herb reniform to orbicular and petiolate Solitary or Raceme
