Cocculus.] PLOHA INDICA. 191 



Our specimens of the stem of Cocr?i/?i.i lorria nrc all small ; one, evidently seve- 

 ral years old, and one-fourth of an inch in diameter, is eom[act, woody, and cylin- 

 drical, with only one zone of wood-wedges. These are separated by very narrow 

 medullary rays, and extend nearly from the pith to the circumference ; they are very 

 much more numerous and closely placed than in C. lauiifuUns, but their compo- 

 nent tissues entirely correspond with those of that plant. 'Older stems may present 

 other concentric zones of wood. 



The stem of C. villosus attains a considerable diameter, but onr specimens are 

 only small branches of the same size and apparent age as those of C. Leaba. The 

 tissues of these only differ from those of the above-named plant and of C. laurifoHus 

 in the outer portion of the pith, which is contiguous to the wedges of wood, becoming 

 smaller and denser, and the cells elongating vertically into woody tubes, with blunt 

 superimposed ends. This is a very common form of pith in Menisperms, varying 

 in proportion to the more strictly cellular pith in different species and individuals. 



In Coccuhis macrocarpus the young shoots have the same structure as those of 

 C villosus, the outer pith-cells next the wood being elongated, woody, and dense. 

 In a shoot nearly half an inch thick there are two zones of wood-wedges analogous to 

 those of G. laurifolius, as described by Decaisne, while an old trunk, more than two 

 inches in diameter, from Chittagong, believed to belong to this species, has a succes- 

 sion of concentric zones of wood-wedges, irregularly arranged around an excentrie 

 axis ; the number of zones on one semi-diameter being eight or ten, and on the other 

 about twenty, owing to occasional union or suppression. The wedges of each zone 

 are separated by thin medullary plates, which do not run in straight lines from the 

 centre to the circumference.

A specimen, in leaf only, collected in the Khasia hills, is very like this species, but 

 cannot in that state be identified with any certainty. A specimen collected in south 

 China by Seemanu has also very similar foliage.
