I have frequently been indebted for the safety of his friend’s

156. SCHIZONOTUS tomentosus. (Spiræa Lindleyana, Wallich cat. no. 703.) 
A handsome and new hardy shrub, from the cold northern 
provinces of India, introduced by the East India Company, 
and recently raised in the Garden of the Horticultural Society. 
It has the habit of Spirza sorbifolia, but has downy leaves, 
and the flowers, with which I am unacquainted, appear from 
the fruit-bearing specimens, to be produced in very large 
panicles. 
The genus Scuizonotus was merely mentioned in Dr. 
Wallich’s catalogue, as one which I proposed to form upon 
this species and Spiræa sorbifolia. It has since been regarded 
by Meisner (tab. gen. diagnost. p. 103), as a section of Spiræa, 
without his being aware of the character on which I conceive 
the genus to be established. I may therefore take this op- 
portunity of stating that, as the name (Splitback) indicates, 
the character is taken from the remarkable cohesion of the 
carpels into a 5-celled capsule, whose cells split open at the 
back for the escape of the seeds. This is I conceive a cha- 
racter of importance enough to eliminate from Spiræa the 
two remarkable looking shrubs in which it occurs. 
157. CATASETUM deltoideum. Bot. Reg. fol. 1896. (Myanthus.) 
In a former volume of this work it has been related how 
the species of Orchidaceous plant which was called Myanthus 
barbatus, with a revolute bearded lip, and a column with 
two feelers, changes by a marvellous metamorphosis, into what 
was also called Monachanthus viridis, thus proving not only 
that the supposed genera Myanthus and Monachanthus are 
the same, but that they are mere forms of Catasetum itself. 
A new case of this kind of variation, previously unheard of 
and unsuspected in the Vegetable Kingdom, has been ob- 
served by Mr. Dunsford, who has brought me a-scape of 
Catasetum deltoideum, figured at fol. 1896 of this work, in a 
similar state of alteration. The scape itself has become three 
times as stout as usual, the length of the raceme is much re- 
duced, the sepals and petals retain their form and colour; but 
the labellum, instead of being arrow-headed, flat, deep purple, 
toothed .at the base, and placed in front of the flower, has 
become of exactly the same form as that of Monachanthus
