Question: Which plant has more species, Microcachrys or Dichroa?

Context paragraphs:
Dichroa: Dichroa is a genus of 12 species of flowering plants in the family Hydrangeaceae, native to eastern and southeastern Asia.  They are deciduous shrubs growing to 1-3 m tall, with their leaves arranged in opposite pairs.  The flowers are produced in a broad inflorescence similar to that of the related genus "Hydrangea".  The fruit is a glossy metallic purple-blue berry.

Diselma: Diselma archeri (Dwarf Pine) or (Cheshunt pine) is a species of plant of the family Cupressaceae and the sole species in the genus Diselma.  It is endemic to the alpine regions of Tasmania's southwest and Central Highlands, on the western coast ranges and Lake St. Clair.  It is a monotypic genus restricted to high altitude rainforest and moist alpine heathland.  Its distribution mirrors very closely that of other endemic Tasmanian conifers "Microcachrys tetragona" and "Pherosphaera hookeriana".

Microcachrys: Microcachrys tetragona (Creeping Pine or Creeping Strawberry Pine) is a species of dioecious conifer belonging to the podocarp family (Podocarpaceae).  It is the sole species of the genus Microcachrys.  The plant is endemic to western Tasmania, where it is a low shrub growing to 1 m tall at high altitudes.  Its leaves are scale-like, arranged (unusually for the Podocarpaceae) in opposite decussate pairs, superficially resembling those of the unrelated "Diselma archeri" (Cupressaceae).  It shares the common name Creeping pine with several other plants.  Females produce tiny, red, edible berries in summer.
