Operculicarya hyphaenoides
IntermediateOperculicarya hyphaenoides
A south-western Madagascan Operculicarya with several thick, warty trunks from one base and finely divided, densely hairy pinnate leaves. Its rounded, squarish leaflets and overall hairiness set it apart from O. pachypus and O. decaryi.
About
Operculicarya hyphaenoides is a deciduous shrub or small tree of the cashew family (Anacardiaceae) endemic to Toliara province in south-western Madagascar. It grows in subarid thicket on limestone from sea level to about 500 m, notably around Lake Tsimanampetsotsa; it is known from five locations with an area of occupancy of about 54 km². Nomadic grazing, commercial logging and wildfire destroy its habitat, and the IUCN Red List category is Endangered. Several thick, gnarled trunks rise from a common base to 1.5 m, occasionally 3 m, and up to 40 cm across, with bumpy, warty bark; its bonsai-like look appeals to collectors. Leaves, three to five per short shoot, are odd-pinnate with 11-20 pairs of rounded-rectangular leaflets about 4 mm long and 2 mm wide with truncate tips, and are densely hairy throughout. They fall in drought, and the tiny flowers are dark red. O. pachypus and O. decaryi resemble each other more closely; this species is told apart by its hairy foliage and leaflet shape. In Japan it is the most traded Operculicarya after pachypus and decaryi, with seedlings sold by specialist nurseries and on online auction sites.

Growing Tips
Light & Placement
Grow in a warm spot in full sun to light shade. It is fairly easy both indoors and outdoors.
Watering
In leaf it needs regular water like any tree, and in a well-drained mix it takes plenty in hot summers. Indoors keep it on the dry side to avoid rot, and reduce water in winter dormancy.
Temperature & Overwintering
From spring to autumn nights of 15°C or more and days of 25-45°C suit it; in winter keep nights above 10°C and days above 18°C. It needs a dry, cool season to flower.
Soil & Repotting
Use a gritty, porous mix at least half inorganic, with excellent drainage. Repot about every three years.
Propagation
Propagate by seed, cuttings or root pieces. Soak seed in warm water for 24 hours before sowing; it germinates erratically over about six months. Seed-grown plants develop better-looking roots.
Pests & Cautions
As an endangered species with a small range, choose nursery-raised seedlings over wild-collected plants to reduce pressure on wild populations.
