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. 



70. DIPLOPELTIS Hugelii. Endl. enum. p. 13. 



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 Capparidaceae rather than of 

 Sapindacese, to which order the learned Dr. Endlicher has 

 referred it. 



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. At a later period he brought the subject before 

 the Academy of Sciences of Paris, and his memoir upon the 

 subject received the Monty on 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
