Ferns and lycophyte specimens in the BRIT herbarium. Many herbaria in the world are represented by curators and research communities that are very familiar with the character and content of their collections, but very few of these have access to accurate numbers and specimen inventories. Digitization funding is a game changer that will provide us with the means to better preserve the collections we hold in public trust. A digitized specimen is a tool that allows access to scientific vouchers and observations that span hundreds of years – an essential component to research that deals with past environmental change and future models. The Philecology Herbarium at the Botanical Research Institute is one of 36 herbaria and museums throughout the U.S. representing the Pteridopytes Collections Co...

There are many plant species bearing the iconic clover look in the Dallas-Fort Worth Metroplex. The true lucky clover is believed to be the white clover of the legume family - Trifolium repens . Although Trifolium is derived from the Latin words tres (three) and folium (leaf), a unique genetic mutation causes some plants to grow an additional leaflet! A simple Google search will tell you the likelihood of a four-leaf clover is 1 in 10,000. However, it was not until 2017 that a study was conducted by enthusiasts to see if this number was accurate. They found the frequency to really be 1 in 5,076 ! This is not the only surprise this species brings to the table. Some of these plants across the world not only grow one extra leaflet, but sometimes up to 8 leaflets. There is even a Guinness Worl...

The BRIT Philecology Herbarium is composed of a melting pot of several orphaned collections across the south and southeast. In addition to those large collections, we also receive specimens through active exchange programs with more than one hundred herbaria across the world. Each of our large collections - BRIT/SMU (Southern Methodist University), VDB (Vanderbilt), and NLU (University of Louisiana at Monroe) - complete one another by filling in geographical and taxonomic gaps of their holdings. Sea hearts ( Entada) These heart-shaped seeds were found in a wood collection acquired from Houston Public Museum. The seeds come from plants in the genus Entada in the legume family (Fabaceae). These plants are typically woody vines, or lianas, that establish themselves along beaches and rivers. T...

The BRIT herbarium has acquired a unique collection of wood specimens (a xylarium) that curators have been organizing over the past few months to make it accessible to researchers and the public. These specimens come in all shapes, cuts, sizes, and varieties of woody plants from across the world! Seven of these specimens that bore no labels or data were brought to curators’ attention and were a complete mystery until more investigating and research was done. The mystery specimens were uncovered to be host roots for Dactylanthus taylorrii – a fully flowering parasitic plant found only in New Zealand. This “wood rose” attaches itself to the roots of trees and shrubs and warps the bark into a rose-like appearance. Read more about the xylarium and this curious specimen...

On Sunday, February 25th, BRIT staff had the pleasure of hosting members of the Southwestern Fern Society, our local chapter of the American Fern Society, for a volunteer day. Six volunteers worked hard to organize and sort ferns and lycophytes from the recently acquired University of Louisiana at Monroe’s (NLU) herbarium collection. Ferns and lycophytes (once referred to as “fern allies”) are two special groups of plants that do not have flowers or seeds but rather reproduce by spores. Happy volunteers and BRIT staff hold "golden tickets" found among the collections. Tickets were exchanged for fun prizes! NLU Collections Assistants Miranda Madrid and Ashley Bordelon and BRIT Research Botanist Dr. Alejandra Vasco led the group on a tour of BRIT’s plant preservation studio, digitization stu...

One of the first steps in curating the NLU collection is ensuring its security. Herbarium specimens are vulnerable to damage from light, bugs, rodents, dust, and water. The metal cabinets used to store herbarium specimens are designed to protect from these damaging elements conveniently and easily – but only if they are in good shape and sealed airtight. Each cabinet of the 328 total we received from the university was inspected to confirm that it was performing its job. Of the 336, there were 156 cabinets with seals that appeared damaged or deteriorated. We decided to make a plan to fix this problem before moving forward with the curation process. Adhesive turned out to be a lot trickier to remove than anticipated! Trying to just peel it off with fingers was frustrating and, frankly, woul...

Mistletoe brings to mind a be-ribboned bouquet hung beneath doorways to catch unsuspecting party-goers in a kissing trap, but the evergreen plant has a long history in Western holiday tradition. The original mistletoe of Greek and Celtic traditions, Viscum album , was a symbol of masculinity, vitality, health, and fertility, and its usage as a treatment for barrenness in human and animals is reportedly very ancient. The majority of mistletoes are obligate hemi-parasites, meaning they cannot live without a host but do engage in some photosynthesis with their foliage. The connection between mistletoe and the Winter Solstice was likely made as the species remains evergreen and bears fruit throughout winter, creating festive decoration is the coldest of winter wonderlands.

The R. Dale Thomas Collection (NLU) officially completed its journey to BRIT in August 2017. However, this was only the beginning! Follow the NLU rescue team for the next year as they work to make this priceless collection secure and accessible to researchers and the public. Prior to its move to BRIT, the R. Dale Thomas Collection (NLU) was housed at the University of Louisiana at Monroe. The herbarium acronym NLU comes from the University’s previous name—Northeast Louisiana University—when Dr. R. Dale Thomas took the collection from 250 specimens to over 400,000. Today, the NLU herbarium contains an estimated 472,000 specimens of vascular and nonvascular plants collected across the globe. The NLU collection has strengths in Louisiana flora and in the daisy family, Asteraceae. Left: The he...
