FDACS DPI Tri-Ology Volume 50, Number 5, September

DACS-P-00124 Volume 50, Number 5, September - October 2011 Printer-Friendly PDF Version 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.

This species is occasionally to the herbarium found in disturbed sites, scattered from Leon County through the peninsula to Miami-Dade County. It is native from the Caribbean and Southern Mexico to Bolivia. In Latin America, decoctions of this plant are used medicinally for topical infections, inflammation, sores, bug bites and other skin irritations. (Marion County; submitted by the general public; 13 September 2011.) (Duke et al. 2008; Howard 1989; Mabberley 2008.) Aristolochia maxima Jacq. (Dutchman's-pipe, Florida Dutchman's pipe), from a genus of 120 species from warm or tropical areas. Aristolochiaceae. This woody vine or liana can twine up to 20 m from its roots. The alternate, leathery, obovate leaves are 7-15 cm long with short petioles from 1-8 mm long. The leaf bases can be cordate or truncate, while the apex has a short, acuminate tip. Inflorescences can be solitary flowers or a fan-shaped cyme with brownish-purple funnel-shaped perianth, composed of three fused sepals. The flower shape, like the meerschaum pipe of Sherlock Holmes, inspires the common name. A chamber, the "utricle," encloses the reproductive structures of the flower and connects to a tube leading to the showy limb. The fruit is an ovoid capsule 10-15 cm long with numerous, flattened, triangular seeds. These elaborate flowers provide a home for the larvae of flies that breed within them, then leave to spread pollen. Other species in this genus use "pollination by deception." The flies confuse the flower with rotting meat, but are not rewarded
