Tabernaemontana donnell-smithii is an evergreen tree in the dogbane family

type locality is San Felipe, Retalhuleu in Guatemala.^[4] Tabernaemontana donnell-smithii is similar to Tabernaemontana glabra, except that its leaves and flowers are smaller and its fruit is larger.^[5]

Tabernaemontana donnell-smithii lives in a variety of habitats, including various types of forest, the forest edge, and pastures.^[5] It grows up to 20 metres (66 ft) tall, although the height is partially dependent on the habitat.^[5] Trees living in secondary growth areas, forest edges and pastures are generally shorter but broader than those in forests.^[5] The flowers are yellow, and may appear at different times of the year depending on the location.^[5] Foster and McDiarmid found that the slow growing fruit is about 7 to 10 centimetres (2.8 to 3.9 in) long and weighs an average of about 143 grams (5.0 oz).^[5] The fruit is enclosed in a woody husk which represents more than three-quarters of the fruit's weight.^[5] When the fruit is open, a slit forms in the husk permitting access to the arils, each of which covers a seed.^[5]

The fruit of Tabernaemontana donnell-smithii is eaten by birds such as

germinate, both by removing the arils from the seeds and also by scarifying the seeds.^[3]^[5]

The bark contains the

alkaloids tabernanthine and voacamine.^[4] The seeds contain the alkaloids coronaridine and tabersonine.^[4]
