Plate from a book. The upper photo shows the parts of the plant, including leaves, fruit, endocarp, and seed. The lower photo shows the seed cut in half to reveal the highly folded and contorted cotyledons.

The only photo I could find was this plate of Mangifera gedebe. In the lower image, that’s all folded cotyledons, not ruminate endosperm! It’s from The Mangoes: Their Botany, Nomenclature, Horticulture and Utilization by A.J.G.H. Kostermans (2012). #seed #cotyledon #Anacardiaceae #Botany

Photo of a seedling emerging among the leaflitter. The two opposite cotyledons are green, leafy and linear in shape. Two adult leaves (and one just emerging) show that the adult leaf morphology is pinnately compound.

As all gardeners know, cotyledons (the pair of seed "leaves") can look very different from the true, adult leaves of a plant. The cotyledons of this Operculicarya decaryi seedling are simple & linear, but the true leaves are pinnately compound. #seed #cotyledon #Anacardiaceae #Botany 🌾🧪🌱

Collage of two photos. The left photo shows a stem with petioles attached (leaf blades have been cut away). The right photo shows the same stem with petiole bases removed to reveal the axillary buds. Photos by Scott Zona CC BY-NC 4.0.

While looking at axillary buds, I noticed this strange phenomenon in Rhus glabra: The petiole base completely covers & conceals the axillary bud, which is revealed (and can grow) only when the leaf has fallen away. #Anacardiaceae #buds #Botany 🌾🧪🌱

My beautiful little cashew is flowering for the first time today. I love the entire Anacardiaceae family, but as far as fruit trees go this is definitely in my top 5.

While hiking in a natural area today I passed a young boy trying to uproot a small poison ivy plant, then giving up and rubbing his face and eyes. I told his mom that it was poison ivy but she gave me dagger eyes and just walked away. That kid is going to be in agony tomorrow. #botany #anacardiaceae

Poison ivy (Toxicodendron radicans) is widely feared, as it causes nasty rashes in many folks, but we are not the only animals interacting with this species. (It's not about us!) The flowers are great for pollinators, & songbirds eat the fruits (→disperse seeds). #Anacardiaceae #Botany 🌾🧪🌱

Here in the temperate zone, the showiness of Anacardiaceae is down to their autumn foliage. This is Rhus copallinum of eastern N. America. The autumnal foliage color is spectacular. #Anacardiaceae #Botany 🌾🧪🌱

Photo of leafy shoots. The tips of the shoots bear red, branched panicles of tiny flowers (or flower buds). Large white leaf-shaped bracts subtend the inflorescences like wreaths.

Close-up photo of a single inflorescence with its red branches and white or very pale pink bracts.

Anacardiaceae are not known for showy flowers. Anacardium braziliense (syn. A. spruceanum) brings the bling with showy bracts subtending the inflorescence (=pseudanthium). 📷1 by esa_bt CCBYNC4. 📷2 by mapoflife_rapidassessments CCBYNC4. #Anacardiaceae #tropicalbotany #Botany 🌾🧪🌱

Close-up photo of a cluster of mango flowers and buds. The flower has five petals (with a dark yellow spot at the base of each), a large nectar disc, and few fertile stamens. Photo by Scott Zona CC BY-NC 2.0.

The flowers of Anacardiaceae are typical for the order (Sapindales). Note the enlarged, donut-shaped nectar disc between the stamens and the gynoecium (pistil). This is the flower of a mango (Mangifera indica) cultivar that has fewer stamens than the wild type. #Anacardiaceae #Botany 🌾🧪🌱

Photo of the leafless branches of a tree against the sky. Clusters of brown, dry, winged fruits hang from the tips of the branches.

#Anacardiaceae fruits are wonderfully diverse in terms of structure & modes of seed dispersal. Amphipterygium (5 spp in seasonally dry forests of Mexico & Central Amer.) has wind-dispersed fruits. This is Amphipterygium adstringens (📷: comuneroschilac CCBYNC4) in the dry season. #Botany 🌾🧪🌱

Photo of a hand holding a leafy branch with a terminal cluster of fruits. The large, fleshy pedicels are yellow and attractive. The true fruits are the C-shaped nuts that are borne on the tips of the fleshy pedicels. The leaves are lanceolate and glaucous on their undersides. Photo by Scott Zona CC BY-NC 2.0.

Semecarpus is an Asian analog of the American Anacardium. Like its American cousin, it has fleshy, attractive pedicels subtending the fruit. Also like its cousin, it has dermatitis-causing chemicals in its tissues, but the seed dispersers are unaffected. #Anacardiaceae #TropicalBotany #Botany 🌾🧪🌱

Close-up photo of a leafy branch with a terminal cluster of three fruits. The large, fleshy pedicels are yellow and attractive. The true fruits are the C-shaped nuts that are borne on the tips of the fleshy pedicels. Photo by Scott Zona CC BY-NC 2.0.

The fruits of cashew (Anacardium occidentale) are unusual. The familiar nut is borne inside the hard-shelled fruit at the distal end of the fleshy, attractive, edible pedicel. I don’t know what disperses the seeds in nature. Primates? Bats? #Anacardiaceae #tropicalbotany #Botany 🌾🧪🌱

some other edible fruits in the #Anacardiaceae include Buchanania, which ranges from about India to northern Australia

This photo looks like a bowl of tomatoes, but these fruits are Spondias purpurea, a tree native to the tropical Americas. Some people love these fruits; I am not one of those people. The fruits are drupes (fleshy, with a seed-enclosing stone). #Anacardiaceae #tropicalbotany #Botany 🌾🧪🌱

#Anacardiaceae are a worldwide family of woody plants, some of which (cashews, mangoes) are economically important. HT to Susan Pell & Matt on the In Defense of Plants podcast for reminding me that, until now, I’ve never devoted a week to this family. 📷: mangoes #tropicalbotany #Botany 🌾🧪🌱

Pink peppercorn fruits matured on the tree

Peruvian Peppertree (Schinus molle, #Anacardiaceae, along with cashew & mango)... An ornamental in So. Calif, it's dioecious, and pink "peppercorn" fruits are blended w/ black pepper (Piperaceae). Known to be allergenic and somewhat poisonous depending on the dose. #NaturalHistory #Botany

Rains falling over Central Florida this evening, which means another cold snap. Looking after my Wild Plum (Harpephyllum caffrum) in the ground today.

Photo of leafy shoots bearing terminal panicles of small red fruits.

Brazilian pepper (Schinus terebinthifolia) flowers attract pollinators, & fruits feed migratory & resident birds. It is, however, a horrific weed that invades & smoothers native plants in some parts of the world, like my home state of Florida. #Goodplantbadplant #Anacardiaceae #Botany 🌾🧪

Photo of the branches of a mango tree and the long, dangling branches that bear the fruits.

Mangos are borne are long, whip-like (flagelliform) stalks. It has nothing to do with access by insect pollinators & everything to do with seed dispersal by #bats (of mango's wild ancestors & relations). Mangifera indica by Scot Nelson CC0 #Anacardiaceae #TropicalBotany #Botany #PlantScience 🌾

Day 70 of #JRBPVirtualTour! The infamous Pacific #poisonoak (#Toxicodendron #diversilobum), woody #vine or #shrub in the #sumac family, #Anacardiaceae. Common in #mesic #riparian zones to #xeric #chaparral habitats. Leaves are divided in three: “Leaves of Three, Leave Them Be”
