FAMILY INDEX

FAMILY CODE: HYPOXI
FAMILY SCIENTIFIC: Hypoxidaceae
FAMILY AUTHORITY: R. Brown 1814
FAMILY COMMON: Stargrass Family
FAMILY SUMMARY: A family of about 9 genera and ca. 155 species, uerous or rhizomatous perennial herbs, subcosmopolitan (though not well distributed in the northern hemisphere of the Old World, and especially diverse in South Africa). The recognition of Hypoxidaceae at the family level is supported by a variety of authors, on morphologic and molecular grounds (Kocyan et al. 2011; Judd 2000).

COMMON NAME: Glossy-seed Stargrass
SYNONYMY: [= FNA, GW, K, RAB, S, Va, WH3, Z; > H. longii Fernald - C, F, G; > H. sessilis - C, F, G]
PHENOLOGY:
HABITAT: Wet pine savannas.
COMMENTS: Apr (-later, especially in response to fire); May (-later, especially in response to fire). NC south to s. FL, west to e. TX, s. AR, and se. OK. The potential recognition of H. longii needs additional assessment as its lumping is presumptive; see Weakley, Ludwig, and Townsend (2013) for discussion.
