Leaf: opposite, sessile or petioled, pairs generally unequal; blade generally entire. Inflorescence: generally forked; spike, head-like cluster, or umbel, flowers rarely 1, bracts forming a calyx-like involucre or not. Flower: bisexual, generally +- radial (bilateral), sometimes cleistogamous in some genera; perianth of 1 whorl, generally petal-like, bell- to trumpet-shaped, base hardened, tightly surrounding ovary in fruit, lobes 3--5, generally notched to +- lobed; stamens 1--many; ovary superior (appearing inferior due to hardened perianth base), style 1. Fruit: achene in hardened perianth base; round to +- flat; smooth, angled, ribbed, or winged; glabrous, hairy, or glandular. Genera In Family: 30 genera, 350 species: warm regions, especially America; some ornamental (Bougainvillea; Mirabilis, four o'clock). eFlora Treatment Author: Andy Murdock, except as noted Scientific Editor: Thomas J.

Common Name: SAND-VERBENA Habit: Annual, perennial herb, generally glandular. Stem: prostrate to ascending, generally +- red. Leaf: generally fleshy, petioled. Inflorescence: head or umbel; flowers maturing outer before inner or +- simultaneously; receptacle conic, +- smooth; bracts 5--10. Flower: perianth salverform to trumpet-shaped, generally fragrant, lobes 4--5; stamens 4--5, included; stigma linear, included. Fruit: body fusiform; wings (0)2--5, lobe-like, prominent, opaque, thick, not continuous above fruit body. Etymology: (Greek: graceful) Note: Closely related to Tripterocalyx; relationships among species Abronia gracilis Benth. (Mexico), Abronia maritima, Abronia umbellata, and Abronia villosa need study; hybrids involve Abronia latifolia, Abronia maritima, Abronia umbellata; Abronia gracilis included in TJM (1993) based on misidentifications. eFlora Treatment Author: Andy Murdock Reference: Galloway 2003 FNANM 4:61--69

2. County and Jepson Region polygons can be turned off and on using the check boxes.
(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
MAP LEGEND View all CCH records 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.
