UTK Herbarium - TENNさんのイラストまとめ

The Lythraceae also includes economically important species like Punica granatum (pomegranate); Trapa bicornis, T. natans, & T. rossica (water caltrop; buffalo nut, etc.); & Lawsonia inermis (henna tree).

What family do you think of when the holiday season comes around?! I bet all of you immediately thought of the Lythraceae & absolutely NO ONE thought of the Euphorbiaceae, right?! Phew!
Get ready for another round of #FamilyoftheWeek, but double the fun w/ ~2 weeks planned!

The other genera in the Agavaceae (or subfamily Agavoideae) growing in #Tennessee are all herbs & have leaves w/out threadlike fibers coming off the margins. The genus Manfreda (false aloe, rattlesnake master) has been lumped w/ the genus Agave by some sources. #FamilyoftheWeek

As you can probably already tell, the genus Agave is another member in this [sub]family, it just doesn’t grow in TN unless it’s cultivated… OR if you lump the genus Manfreda in with it. Check back all week to learn about these plants & how they’ve been treated! 💚

The genus Rhus (sumac) is represented in #Tennessee by 4 species. These all have odd-pinnate leaves, like Toxicodendron spp., but produce bright red, glandular pubescent fruits & do not produce urushiol, the rash-causing irritant Toxicodendron spp. produce. #FamilyoftheWeek

It’s another #FamilyoftheWeek & this time we’re covering the Anacardiaceae (cashew family)! This family includes other tasty members, like pistachios & mangos 😍, & very NOT tasty members like poison ivy. 😖

Bignonia is represented in TN by 1 species, B. capreolata (crossvine). The compound leaves have 2 leaflets & a terminal branched tendril. You can find this all over the state in swampy forests, bottomlands, & thickets. It’s even on the cover of Guide to the Vascular Plants of TN!

The members of the Bignoniaceae that grow as vines in #Tennessee are the genera Bignonia (crossvine) & Campsis (trumpet creeper). Both have compound leaves, but the number of leaflets & the presence/absence of tendrils are the key characters to tell them apart. #FamilyoftheWeek

The members of this family found in TN grow as either woody vines (lianas) w/ opposite, compound leaves & yellow or red flowers or as trees w/ simple, entire leaves & white to yellow flowers. Tomorrow we’ll begin w/ the vines!

Geranium maculatum (wild or spotted geranium) is the only perennial of this genus we have in #Tennessee & it grows from a rhizome. The pedicels have non-glandular hairs. It’s native to TN & grows in mesic woods & roadsides across the state.
