Tiquilia palmeri


Higher Taxonomy
Family: EhretiaceaeView Description 
Habit: Perennial herb to shrub [tree], hairy to glabrous. Leaf: simple, alternate, entire to crenate [dissected], petiolate; stipules 0. Inflorescence: axillary [terminal] cymes or flowers 1, sometimes congested. Flower: bisexual [unisexual, plants dioecious], generally radial; calyx lobes 5, fused or free to base; corolla lobes 5, fused, generally rotate or bell-shaped to urn-shaped; stamens 5, epipetalous, generally exserted; ovary superior, generally subtended by disk-like nectary, chambers 1--4, style terminal, 2-branched, stigma club-shaped or head-shaped. Fruit: generally separating into two 2-seeded drupe-like units, four 1-seeded drupe-like units, or four nutlets.
Genera In Family: 7 genera, +- 150 species; worldwide distribution, especially in tropics and subtropics. Note: Included in Boraginaceae in TJM2 and some other treatments (Angiosperm Phylogeny Group IV 2016 Bot J Linn Soc 181:1--20) but treated as separate family by Boraginales Working Group (Luebert et al. 2016). Lennoaceae nested within Ehretiaceae in some molecular phylogenetic analyses.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
