A past ‘Explains the Name’ column focused on the word ‘foli’ which is Latin for leaf. Today’s column focuses on the Greek word for leaf: ‘phyll’ (or phyl or phyllum).
(Perhaps you’re familiar with filo or phyllo dough - thin leaves of dough)
Below please notice that in the first word of the plant name (the genus) or in the second word of the plant name (the specific epithet) there is the word phyl, phylla, or phyllum, meaning leaf or leaves.
Baptisia alba macrophylla (White Wild Indigo) ‘macro’ in Greek means ‘large’: large leaves
Dasistoma macrophylla (Mullein Foxglove)
Eurybia macrophylla (Big-leaved Aster)
Physalis heterophylla (Clammy Ground Cherry) ‘hetero’ is Greek for different: the shape and edges of the leaves are irregular or different
Chaerophyllum procumbens (Wild Chervil) chairo is Greek for ‘to please’ therefore meaning the plant has pleasant foliage.
Mitella diphylla (Bishop's Cap) ‘di’ comes from Greek meaning two: A single pair of two leaves is on the stem below the flower
Stylophorum diphyllum (Celandine Poppy)
Arisaema triphyllum (Jack-in-the-Pulpit) ‘tri’ comes from the Greek meaning three: this plant has three leaves
Symphyotrichum urophyllum (White Arrowleaf Aster also known as Tail-leaved aster) ‘uro’ comes from Greek meaning ‘tail’
Caulophyllum thalictroides (Blue Cohosh) ‘caulo’ is Greek for stalk or stem
Hydrophyllum virginianum (Virginia Waterleaf) ‘hydro’ is Greek for water
Podophyllum peltatum (Mayapple) ‘podo’ comes from Greek meaning foot. The shape of the leaf resembles a foot or perhaps a duck’s foot.

September 23rd 2021 - Allison Sacerdote-Valet
7:00-8:30 PM - "Direct Effects of an Invasive buckthorn Metabolite on Amphibian Embryo Survival and Development" a Zoom presentation.
Please join us as we zoom in and welcome back Allison Sacerdote-Valet, Curator of Herpetology at Chicago Academy of Sciences/Peggy Notebaert Nature Museum as she gives her presentation, "Direct Effects of an Invasive buckthorn Metabolite on Amphibian Embryo Survival and Development"
Most people know Dr. Sacerdote-Velat as one of the leading authorities on Green Snakes but did you know she is one of the foremost authorities on buckthorn? Please join us for this most informative talk on Prospect Height's public enemy # 1, buckthorn! Dr. Sacerdote-Velat will tell you just how bad this guy is and why we all want to remove it!
European buckthorn (Rhamnus cathartica), exhibits aggressive growth in amphibian breeding sites and releases the secondary metabolite, emodin, into soil and water. Emodin is known to have several deleterious, bioactive properties in mammals and birds, but its effects on amphibians had not been previously assessed.
