THEOPHRASTACEAE THEOPHRASTA FAMILY

Anita F. Cholewa

Perennial herb [shrub, tree], [generally glandular-hairy]. Leaf: simple, alternate but generally clustered at stem tips, petioled, stipules 0, margins entire [spiny-toothed]. Inflorescence: generally terminal, [rarely flowers 1 in axils]. Flower: bisexual [unisexual, plants dioecious], radial, parts generally in 5s, generally with glandular dots, lines, or pits; sepals free or united at base; corolla united at base, lobes spreading; stamens epipetalous, opposite corolla lobes, anthers forming cone as flower opens, then spreading; staminodes 5, alternate stamens, epipetalous, scale-, petal-, or stamen-like; ovary partly inferior, 1-chambered, placenta free-central or basal, style 1, stigma head-like. Fruit: capsule [generally dry berry or drupe]. Seed: 1–many, generally yellow to orange-red.
7–9 genera, ± 100 species: generally tropical America. [Caris & Smets 2004 Amer J Bot 91:627–643] Incl in Primulaceae in TJM (1993). —Scientific Editor: Thomas J. Rosatti.
Unabridged note: Incl in Primulaceae in TJM (1993). The partially inferior ovary as well as aspects of staminode anatomy are unusual for Primulaceae. Recent research (Källersjö et al. 2000 Amer J Bot 87:1325–1341) has shown that Samolus is a sister-taxon to Theophrastaceae, providing evidence for its removal from Primulaceae.

SAMOLUS
Erect, glabrous. Leaf: cauline or basal and cauline, alternate. Inflorescence: raceme, terminal and axillary. Flower: corolla > calyx, white. Fruit: spheric, valves 5, opposite calyx lobes.
± 10 species: ± worldwide. (Celtic: from curative properties)

S. parviflorus Raf. SEASIDE BROOKWEED
NATIVE
Stem: 1.5–4 dm. Leaf: 2–5 cm; blade lance-oblong to obovate, generally tapered to winged petiole, tip obtuse to rounded. Inflorescence: pedicels ascending to spreading, 1–2 cm, with 1 bractlet ± near middle. Flower: calyx 1–2 mm, lobes triangular; corolla ± 1.5 mm across. Fruit: ± 2.5 mm wide.
2n=26. Moist sites; generally < 1300 m. Great Central Valley, Central Western California, South Coast, n Channel Islands, Western Transverse Ranges, San Bernardino Mountains, Peninsular Ranges; to British Columbia, eastern North America, South America. [Samolus floribundus Kunth] Samolus ebracteatus Kunth (leaves crowded near stem bases; bractlets, staminodes 0), from Baja California and Clark Co., Nevada, expected in extreme southeastern California. Spring–summer [Online Interchange]
