It is true that Maximowicz had only a fruiting specimen before 
him when he described Plagiorhegma, and, in failing to discover 
any pom io stamens, he came to the erroneous conclusion that 
the flow were unisexual. But I can see no reason 
for the stsiienioat that the flowers were abnormal. Maxi- 
mowicz’s figure is an excellent one and depicts P. dubia 
just a = type te taba and as the plant grows in the Rock 
Garden ew. Subsequently flowering specimens were gathered 
in N iain ‘tae: China b aa ohn Ross, and were received at Kew in 
1877, an additional specimen n being received from the Petrograd 
herbarium in 1910. On dissecting these I find good ang 
in the flowers, as well as in the leaves and fruits as noted by
