<i>Elatine </i>L. (Elatinaceae Dumortier; waterworts) is a cosmopolitan genus of about 25 aquatic plant species in the order Malpighiales. The genus is interesting taxonomically for two main reasons. First, no systematic studies have been made on the genus using recently available molecular techniques. Second, two species from this genus (<i>E. triandra </i>Schkhuhr and <i>E. ambigua</i> Wight) have been reported as invasive in recent decades. There, also, are indications of polyploidy in the invasive species, which make the genus particularly interesting from both ecological and systematic standpoints. Botanists disagree on the delimitation of several <i>Elatine</i> species. For example, descriptions provided for <i>E. americana </i>and <i>E. minima </i>in various floras often can be applied to either species. This problem results in a high degree of overlap for morphological characters used in such regional floristic treatments. In order to better distinguish each <i>Elatine</i> species, we assembled a data matrix of 37 morphological characters scored from more than 10 specimens per species. We analyzed the data using phenetic techniques (such as neighbor-joining) to search for potential discontinuities among taxa. In addition, we obtained new morphological characters using scanning electron microscopy (SEM) to examine the fine structure of <i>Elatine</i> seeds. Seed analysis using SEM indicated that several differences in seed surface morphology were potentially useful taxonomically, i.e.: length to width ratio, degree of seed curvature, and number of seed surface pits. These characters are promising for clarifying the taxonomy and systematic relationships of the genus at or above the species level.

Biology/Physics Building Room 130, 9:00am to ~ 4:00pm



The EEB Graduate Student Symposium is an all day event where graduate students present their research to other graduate students and faculty. Any EEB graduate student can present: BSMS, masters, PhD, old and new students. New graduate students usually present research ideas or preliminary data, while those more ‘seasoned’ students present their most recent results, often in preparation for upcoming spring and summer meetings.

Title: Advances in understanding systematics and ecology of the mysterious aquatic plants: Elatine L. (waterworts)

Elatine L. (Elatinaceae Dumortier; waterworts) is a cosmopolitan genus of about 25 aquatic plant species in the order Malpighiales. The genus is interesting taxonomically for two main reasons. First, no systematic studies have been made on the genus using recently available molecular techniques. Second, two species from this genus (E. triandra Schkhuhr and E. ambigua Wight) have been reported as invasive in recent decades. There, also, are indications of polyploidy in the invasive species, which make the genus particularly interesting from both ecological and systematic standpoints. Botanists disagree on the delimitation of several Elatine species. For example, descriptions provided for E. americana and E. minima in various floras often can be applied to either species. This problem results in a high degree of overlap for morphological characters used in such regional floristic treatments. In order to better distinguish each Elatine species, we assembled a data matrix of 37 morphological characters scored from more than 10 specimens per species. We analyzed the data using phenetic techniques (such as neighbor-joining) to search for potential discontinuities among taxa. In addition, we obtained new morphological characters using scanning electron microscopy (SEM) to examine the fine structure of Elatine seeds. Seed analysis using SEM indicated that several differences in seed surface morphology were potentially useful taxonomically, i.e.: length to width ratio, degree of seed curvature, and number of seed surface pits. These characters are promising for clarifying the taxonomy and systematic relationships of the genus at or above the species level.
