Which plant has more species, Barklya or Ajuga?
Barklya Barklya is a genus of Australian trees in the legume family, Fabaceae. It belongs to the subfamily Caesalpinioideae. The sole species is Barklya syringifolia, commonly known as the leather jacket or crown of gold tree. It grows in rainforest to 18 metres tall. Recorded from Queensland and New South Wales in vine forest and softwood scrub. It is often used as an ornamental. It may be extinct in New South Wales.
Cornus alba Cornus alba (red-barked, white or Siberian dogwood) is a species of flowering plant in the family Cornaceae, native to Siberia, northern China and Korea. It is a large surculose shrub that can be grown as a small tree. As a popular ornamental used in landscaping its notable features include the red stems in fall (autumn) through late winter, the brightest winter bark of any cornus; and the variegated foliage in some cultivars, such as "C. alba" 'elegantissima', in which the discreet flat whitish flower clusters are almost lost in the variegated texture and dappled light. "C. alba" can grow to 3 m high, but variegated forms are less vigorous. For the brightest winter bark, young shoots are encouraged by cutting to the ground some older stems at the end of the winter, before leaves are open.
