The seagrass Halophila is characterized by a constant organization of its horizontal axes (rhizomes) and variation in the organization of differentiated lateral axes (erect shoots) that have diagnostic value. The lateral axis is shown to have positio

Over the years, workers have gathered data from various sources in the attempt to understand the evolutionary histories and relationships of the domesticated members of Cucurbita. We used allozyme data to address questions of genealogy, interspecific

Artabotrys hexapetalus is widely planted in the tropics and is known as "climbing ylang-ylang," an ornamental liana or woody climber. New natural sprouts, or water shoots, and those induced by the damage of Hurricane Andrew (24 August 1992) were coll

Many improvements have been made in the technique of epi-illumination light microscopy. These modifications have resulted in micrographs of better resolution and subsequently in greater flexibility in the study of floral and vegetative apices. The pr

Growth pouches were used to establish ectomycorrhizae of Pinus strobus using Pisolithus tinctorius as inoculum. An epi-illumination technique was used to follow changes in external morphology of short roots as they became colonized by hyphae and dich
