Trifoliate leaves with dark green, lanceolate leaflets. Small yellowish flowers in open panicles. Small tree.
In the second photo Myrmicaria ants are tending aphids on the inflorescence.
Giant yellow mulberry.Underatorey tree with a short trunk, with branches from near base. Crown spreading, 10m. Still roots often present. Bark thin, smooth,brown. Slash usually white with brown brown lines but occasionally red, turning darker. Leaves digital, red when young with 5-7 leaflets. Leaflets 25×9 cm but sometimes larger , coarsely toothed. Fruit hard, spherical, 3-8 cm diameter, with moderate number of closely- packed seeds.
A deciduous tree up to 30 m in height, with a spreading umbrella-based or rounded crown. The trunk is curved or crooked, dark light brown and vertically vissured. The slash is soft, white to yellow- brown, sometimes with darker lines, darkening rapidly to dark grey-black on exposure to the air. The leaves are alternate, simple, ovate to suborbocular, 6 to 20 cm long and 6 to 13 cm wide ( exceptionally up to 36 cm long and 18 cm wide). The leaf has an acute apex, acuneate to cordate and often assymmetrical base and an entire or shallowly crenate margin. The petiole is channelled and slender, 3 to 10 cm long, without stipules. The lamina is coriaceous, green and rough above , brownish-green with short hairs beneath bearing 3 to 5 veins from the base, palmately arranged and with 5 to 6 upper pairs of lateral veins conspicuous on both sides. The inflorescence is a terminal panicle of scorpiod cymes, 10 to 15 long, bearing hermaphrodite flowers, very conspicuous on top of trees, Sweet scented, on pedicels up to 1 cm long. Calyxes are brown and hairy, 1 cm long, tubular, with 10 to 12 well marked ridges. The corolla is white, 2cm long, funnel shaped with an undulate margin. The fruit is an ovoid drupe, yellowish brown, 1.5 cm long, in which a singe stone containing 4 to 6 seeds is embedded.
A deciduous tree up to 35 m in height, usually with a straight trunk armed with conical woody prickle-bearing protuberances up to 3 cm in length and a spreading crown. The bark is grey-brown, fairly smooth, with small, vertical fissures. The slash is yellow- brown and off-white, yellow near the wood fragrant, sometimes turning darker on exposure to the air. The young branches are glabrous and armed with reddish-brown, straighter or slightly curved pickles, which are 2 to 8 mm long. The leaves are in terminal clusters, alternate, imparipinnate, 25 to 100 cm long, with 7 to 27 leaflets. The rachis sometimes carries a few pickles. The petiole is 5 to 10 cm long, flattened above and swollen at the base. The leaflets are alternate to subopposite, elliptic- oblong to elliptic, 13 to 20 cm long and 3 to 6 cm wide, with an accuminate obtuse apex, an unequal base and an entire margin. The lamina is coriaceous, glabrous, with numerous but small and almost inconspicuous gland dots. The midrib is prominent beneath , sometimes bearing sparse prickles, with 8 to 14 pairs of lateral nerves. The lamina is fragrant when crashed and carried on a petiolule to 1.5 cm long. The inflorescence is a terminal or axillary panicle, 20 to 34 cm long, bearing many small, white, bisexual Flowers, which are clustered, sessile or shortly pedicellate. The male flowers have 5 stamens, while the female flowers have 5 stamen-like structures. The fruit is reddish, splitting open to release one black to purple shiny seed. The seed is 3.5 to 6 mm in diameter and tastes of peppermint.
Occurs along riverine sections of Ragati river and other rivers coming off Mt. Kenya. Seemingly found close to rivers, not on higher ground between water courses.
