flowers like those of C. alorifolium, only streaked and stained 
with very deep crimson. The species is readily distinguished 
by having a sac at the base of the lip.

For a living specimen of this beautiful and most curious 
herbaceous plant I am indebted to Mr. Toward, Gardener to 
H.R.H. the Duchess of Gloucester at Bagshot. It is in its 
present state a foot and half high, with corymbose panicles 
of pink flowers, resembling those of a Cleome. It will be 
speedily figured in this work, when I shall endeavour to shew 
that it is an anomalous form of Capparidacee rather than of 
Sapindacee, to which order the learned Dr. Endlicher has 
referred it. 5 
CIRCULATION OF THE BLOOD IN PLANTS. 
Some years ago, Professor Schultz, of Berlin, called the 
attention of Botanists to the existence in plants of motion 
in a particular fluid, called by him latex, analogous to the 
blood of animals, through a system of vessels previously un- 
examined. Ata later period he brought the subject before 
the Academy of Sciences of Paris, and his memoir upon the 
subject received the Montyon prize. Notwithstanding the 
exact manner in which Professor Schultz described this new 
circulating system, and the great importance of the facts he 
narrated, the question has attracted but little attention till 
lately, the common opinion among vegetable physiologists in 
this country having been, that there was some mistake in 
observations which had been made. 
There can, however, be no doubt upon the. subject, now 
that the circulation has been seen by so many persons in 
England, and the interest belonging to the inquiry is so 
great as to induce me to give the following abstract of a 
paper recently published upon this subject by Professor 
Schultz in the Annales des Sciences, vol. 10. p. 327, new 
series. 
After adverting to the advanced state of the engravings 
with which the Academy of Sciences intend to accompany 
the original memoir, the printing of which was about to 
commence in September last, the author observes, that some 
persons have confounded the motion of cyclosis in the vessels 
dispersed through the cellular tissue. beyond the focus of
