Hoover's Downingia

Downingia bella

Downingia bella, also known as Hoover's calicoflower or Hoover's Downingia, is a member of the Bellflower Family (Campanulaceae). The genus is named after A. J. Downing (1815-1852) a noted American horticulturist and landscape architect. This native annual herb is endemic to California and found in valley grassland communities. Its habitat is wetlands, generally vernal pools between 4600 and 5250 feet (1400 to 1600m). As approximately 90% of vernal pools in California have been lost, D. bella is uncommon. The range of D. bella is scattered from locations in Riverside County to areas in the Great Central Valley. Like all Downingia, the stem is decumbent to erect with leaves that are along the stem and often fall before the plant flowers. The flowers are sessile and in a spike inflorescence with individual flowers having a corolla length of 10 to 12 mm. The corolla is glabrous and has 2 distinct lips, the upper with 2 lobes and lower with 3 lobes. The upper lobes are narrowly triangular or elliptic in shape while the lower lobes are obtuse and abruptly toothed. The corolla is blue with the lower lip having a central white field which then has two yellow spots (can be joined) in its middle. At the throat D. bella has 2 raised nipples that generally have 3 alternating purple spots. The 5 fused stamens have anthers that are included in the corolla tube and are angled less than 45 degrees to filaments. The inferior ovary is pedicel-like and is 2 chambered. The fruits of D. bella are between 16 to 18 mm with tough lateral walls that are tardily dehiscent despite no noticeable translucent lines. The seeds within the fruit are longitudinally striate. Some areas in northern Sutter County have D. bella with a minute corolla horn similar to D. ornatissima. Wikimedia Commons has media related to Downingia bella.

Upright Burhead

Echinodorus berteroi

Echinodorus berteroi (upright burhead or cellophane sword) is an aquatic plant species in the Alismataceae It is native to the southern and central parts of the United States, as well as Central America, the West Indies, and South America as far south as Argentina. Submersed leaves often modified into phyllodes, 10 - 45 cm long x 0. 5 - 4 cm wide, linear to narrowly elliptical, of very variable shape and size, light-green, membraneously transparent, network between the veins often lighter or darker, thus the submersed leaves often appearing mosaic-like coloured. Emerse leaves long-petioled, 5 - 55 cm long, blades light-green, cordate, 5 - 12 cm long x 3 - 5 cm wide, in terrestrial dwarf forms the blades are ovate, truncate at the base, 2 - 5 cm long x 1 - 2 cm wide. In the blades there are very clear pellucid lines 1 - 5 mm (exceptionally up to 11 mm) long. Stem upright, inflorescence compound, branched in lower whorls. In terrestrial forms stem only 6 - 10 cm long. Corolla white, about 1. 5 cm in diameter, stamens 12, achenes numerous in echinate head, nutlets grey-brown, 2. 5 - 3. 5 mm long x 1 - 1. 3 mm wide, broadly keeled, with 2 winged ribs alternating with 3 non-winged ribs; facial gland single, close to the beak, indistinct or quite absent. Mature specimens may have between 10 - 30 leaves. most of them differing in shape and size. Prefers a larger tank with a deep, rich substrate and good light. It is easy to grow but will soon outgrow the average aquarium. Can be divided, or in submerse plants, adventitious plantlets will form on the infloresence and can be divided and planted out. Seed will be set in emerse plants, and can be planted out in shallow trays with sand and shallow warm water. Prefers soft, rather acid water. Sub-tropical to tropical temperatures. It doesn't seem to thrive in hard water. Will grow in and by the pond in warmer regions, but must be protected from frost.
