Droguetia Gaudich.
[FZ]
Urticaceae, I. Friis. Flora Zambesiaca 9:6. 1991
- Morphology General Habit
- Slender annual or perennial herbs, occasionally subshrubs, with erect or prostrate stems, monoecious or apparently dioecious (by abortion of all bisexual inflorescences leaving only female flowers).
- Morphology General Cystoliths
- Cystoliths dot-like.
- Morphology Leaves
- Leaves alternate or opposite, petiolate, serrate; stipules lateral, free.
- Morphology Reproductive morphology Inflorescences
- Inflorescences of sessile clusters in the leaf axils; clusters either bisexual with few-many flowers surrounded by a common campanulate involucrum of fused bracts or inflorescence clusters of many very small involucres each with 1(2) female flowers (the involucres then appear as perianths).
- Morphology Reproductive morphology Inflorescences Bracts
- Bisexual involucres usually with many male flowers and 1 -few female flowers (occasionally all the flowers are male); bracts and flowers with long woolly hairs.
- Morphology Reproductive morphology Flowers
- Female flowers naked, pedicellate, consisting of an ovary covered with a woolly tomentum; stigma sessile, filiform; staminodes absent Entirely-female involucres are common on certain individuals, and then much smaller and with much fewer flowers than the bisexual involucres. Male flowers pedicellate, club-shaped; perianth 3-lobed, one lobe apiculate and provided with prominent bristles; stamen 1, inflexed in bud, later reflexed; rudimentary ovary absent.
- Morphology Reproductive morphology Fruits
- Achene enclosed in the persistent involucre, brown, shiny, often crowned by the persistent stigma.

- Morphology General Habit
- Annual or perennial herbs, occasionally subshrubs, with erect or prostrate stems, usually monoecious (or plants with only ♀ flowers by abortion of all bisexual inflorescences)
- Morphology Leaves
- Leaves opposite or alternate, petiolate; cystoliths punctiform; stipules lateral, free
- Morphology Reproductive morphology Flowers
- Flowers in sessile inflorescences, single or few–many together, surrounded by an involucre of fused bracts; inflorescences bisexual or unisexual by abortion (and then usually ♀), axillary and/or in terminal spikes (if each involucre contains only 1(–2) ♀ flowers, the number of involucres in each leaf-axil is usually high) Female flowers without perianth, consisting of a pistil only; style filiform Male flowers ± boat-shaped; perianth cylindrical to conical at the base, open along one side and with a ± erect tip, enclosing 1 at first inflexed, later reflexed stamen; rudimentary ovary absent
- sex Male
- Male flowers ± boat-shaped; perianth cylindrical to conical at the base, open along one side and with a ± erect tip, enclosing 1 at first inflexed, later reflexed stamen; rudimentary ovary absent
- sex Female
- Female flowers without perianth, consisting of a pistil only; style filiform
- Morphology Reproductive morphology Fruits
