the predominant, though not invariable, structure in End- 
licher’s class Thymelee. 
“ Owing to its possessing this peculiar structure, the genus 
Viburnum appears more nearly related to these orders and to 
Loranthacee than might at first sight be suspected. Zoran- 
thacee and Caprifoliacee have long been associated as nearly 
related orders, though apparently with little propriety, as the 
former is assuredly more justly referable to the 7, hymeleous 
group than to either Araliacee or Caprifoliacee, with which it 
is now associated. The intervention, however, of Viburnum, 
with the flowers and habit of the one, and the ovary and fruit 
of the other, teıfds materially to strengthen the previously 
existing, but remote relationship.” 
An examination of various Viburnums shews that Dr. 
Wight’s statement of the true structure of the genus is quite 
correct. Wecan say that in V. oxycoccus, Opulus, dentatum, 
Lantana, cotinifolium, davuricum, Lentago, pyrifolium, and 
carolinianum, the ovary is uniformly one-celled, with a single 
pendulous anatropal ovule, although there are from two to 
three stigmas. This circumstance confirms in a remarkable 
manner the near relation that certainly exists between the 
Cinchonal and Asaral alliances, which in fact differ in little 
except the dichlamydeous monopetalous flowers of the one 
and the monochlamydeous flowers of the other.
