DPI's Bureau of Entomology, Nematology and Plant Pathology (the botany section is included in this bureau) produces TRI-OLOGY six times a year, covering two months of activity in each issue. The report includes detection activities from nursery plant inspections, routine and emergency program surveys, and requests for identification of plants and pests from the public. Samples are also occasionally sent from other states or countries for identification or diagnosis.

Highlights Following are a few of the notable entries from this volume of TRI-OLOGY. These entries Section Reports are reports of interesting plants or unusual pests, some of which may be problematic. See Section Reports for complete information. Botany

The corollas are deep rose-purple to pinkish purple with five pubescent lobes that have ciliate margins. The upper lobes are reflexed, and the throat is marked with dark purple spots and two yellow lines. The fruit is a more or less spherical capsule with reticulate seeds. Agalinis species are larval hosts of the common buckeye butterfly, Junonia coenia Hübner. In the fall, when their brightly colored flowers attract human attention to roadsides or natural areas where the plants are found, closer inspection can reveal numerous buckeye caterpillars hard at work, eating the dark green or reddish leaves.

The stem of this shrub or small tree, usually 5-10 m tall, has dark brown outer bark and pinkish inner bark. Twigs, young leaves and flower pedicels are covered with rusty brown hairs. The leaves are opposite, evergreen, ovate to elliptic, 8-15 cm long, 4-7 cm wide and variable in the shape of tip and base. The inflorescence is a raceme, equaling or longer than the leaves and many flowered. The five-petaled corollas are yellow, turning dull red with age, and about 1.5-2 cm across. The fruits are drupes, 8-12 mm in diameter, dull yellow or tinged with orange. This fruit is much prized, especially in Brazil, where it is sold fresh, as a juice or in ice cream and called "muruci." In other areas where it grows, the fruit has been compared to a bland apple. The species is popular as an ornamental as well Buckeye butterfly larva on Agalinis sp.

Dr. University of Florida David Fairchild brought seeds from Panama to Florida in 1899 for the United States Department of Agriculture, and the tree continues to be occasionally cultivated as an ornamental. Although the grain of the wood is described as roey (interlocked, irregular or wavy), the tree is sometimes used for construction in South America. Medicinal uses of the plant include treatments for respiratory ailments and digestive problems including dysentery, as well as the ubiquitous remedy for snakebite. This species is native to the West Indies, Mexico and northern South America. (Indian River County; B2012-567; Kenneth L. Hibbard; 18 October 2012 and Orange County; B2012-598; Ricardo E.

Chrysopogon aciculatus (Retz.) Trin. (golden false beardgrass), from a genus of about 44 species (now including Vetiveria), native to warm areas of the Old World, but with one species, C. pauciflorus, native to Florida. Gramineae. This perennial grass grows by stolons that spread quickly over the soil or become buried shallowly in the soil. Overlapping scales or old leaf sheaths cover the stolons. Leafy, sterile, short shoots may grow from the stolons as well as fertile stems 15-25 cm tall with leaf sheaths that can have pale stripes of green and white or darker and lighter green or with hints of purple. The leaf blades are 2-8 cm long, 3-5 mm wide, with scabrous margins. The reddish-purple inflorescence is a panicle, 3-6 cm long. Branches of the panicle are whorled and held stiffly upward.

(golden false beardgrass) inflorescence spikelet clusters are 6-8 mm long and break from the pedicel (flower stalk) Photograph courtesy of Forest and Kim Starr along a diagonal ridge that becomes a sharp, bearded barb about 3-7 mm long, covered with golden brown hairs. The seed or grain is about 2 mm long. The barb remains attached to the seed to aid in its spread in fur or on clothing. The grass is usually found in sunny, dry, exposed areas such as roadsides, lawns and pastures. It is native to tropical India and China, and parts of the Pacific region, but has been widely introduced in other tropical areas of Asia, Australia and the Pacific. This grass was found in Homestead by Keith Bradley of the Institute for Regional Conservation. A sample was provided for confirmation of the species identification of this federally listed noxious weed. See the DPI Pest Alert for additional information.

Maladera castanea, the Asiatic garden beetle, a new Florida State Record. The Asiatic garden beetle was collected in northeastern Florida in May 2012. The larva (a white grub) of this scarab beetle is known as a turf pest, and adults are known to feed on tender foliage and flowers. Occasionally, their populations reach a size large enough to become a nuisance at lights. This species has been present in the northeastern United States since the 1920s and has been moving slowly southward. Conditions of its collection in Florida indicate it is now established.

In view of the popularity of this rose series, plant health specialists everywhere should be on the alert for similar problems in their areas. (Dr. Timothy S. Schubert.)
