Harley, R.M. 2015. Physominthe (Hyptidineae, Lamiaceae), endemic to Brazil, with a new species, P. longicaulis, from Bahia. Kew Bulletin 70: 1. DOI https://doi.org/10.1007/s12225-014-9551-8

Morphology General Habit
Shrubs, subshrubs or herbs, weakly aromatic. Stems virgate, erect, upper internodes glabrous, pruinose, usually fistulose and inflated (strongly so in P vitifolia), nodes and lower stems often with long, rigid setose hairs
Morphology Leaves
Leaves lobed or unlobed, toothed
Morphology Reproductive morphology Flowers
Flowers very shortly pedicellate, small, subtended by reduced, linear, inconspicuous bracteoles
Morphology Reproductive morphology Flowers Calyx
Calyx ± actinomorphic, turbinate at anthesis, becoming campanulate to tubular in fruit
Morphology Reproductive morphology Flowers Gynoecium Style
Style deciduous with base overtopped by ovary
Morphology Reproductive morphology Flowers Gynoecium Stylopodium
Stylopodium absent
Morphology Reproductive morphology Fruits
Nutlets weakly trigonous and flattened, irregularly ribbed, mucilaginous when wet.
Morphology Reproductive morphology Inflorescences
Inflorescence branched with elongate branches, thyrsoid, lax, formed of pedunculate, subumbellate, few-flowered cymes, 3- to 9-flowered, from the axils of minute, subulate bracts
Morphology Stem
Details of possible function of stem swellings have been published elsewhere (Harley 1991)
Note
Similar, in its virgate habit with upper internodes inflated, glabrous and pruinose, to Hypenia, in which it was formerly included, and some species of Eriope, and differing from all species of both these genera in possessing flowers in pedunculate few-flowered cymes and lacking a pair of minute bracteoles at base of calyx. Chromosome numbers 2n = 22, 28 (2n = 20 in Eriope and 2n = 20, 12 in Hypenia). See Harley & Heywood (1992). The genus is endemic to eastern and north-eastern Brazil, and composed of two species restricted to upland cerrado, carrasco and caatinga areas, usually overlying sand, in Bahia, Minas Gerais, Goiás and São Paulo.

Native to:

Brazil Northeast, Brazil Southeast, Brazil West-Central
