The monocotyledons have also their representatives amoni>;st these 

 ropes. There are two species, perhaps belonging to the Grasses, which I 

 have met with ; hut in neither case is the entire stem used. One spe- 

 cies is much larger than the other, their diameters being about two inches 

 and four inches respectively ; both are hollow, and are divided into strips. 



Specimens are found amongst these ropes which belong to other 

 Natural Orders, such as the Menispermacece, Guctacece, Asclepiadacece, 

 etc., but our knowledge of them is too limited to assign them to their 

 respective Orders. Most of my specimens have come from bales of 

 Santos Cotton. I am very anxious to get some from the Pacific coast, 

 wliere many species differing from Brazilian species must be found. 

 Gaudichaud mentions the neighbourhood of Guayaquil, in Ecuador, as 

 being particularly prolific in Lianas. 



A specimen was sent me from the Liverpool docks by Mr. Griffiths, 

 'whose structure is so puzzling that I know not whether to call it dico- 

 tyledonous or monocotyledouous. It consists of a central spongy 

 mass of woody tissue apparently without medullary sheath, pith, or 

 medullary rays, and arranged in the form of a pentagon formed of 

 semicircular lobes, the whole being surrounded with what appears to 

 be liber which has shrunk away from the very thick and hard external 

 bark, so as to leave the woody core isolated within it. The core con- 

 sists of woody fibres, but half its area is taken up with wide-mouthed 

 vessels.

A few months ago we noticed in this Journal (p. 125), the first 



half of the second volume of the above work, which, with that now 



beibre us, treats of the Lichen flora of these districts. Like the 



former half, the present one is illustrated with numerous engravings of 



typical species and their spores in the different families and genera. 



As it completes the enumeration and description of these apparently 



well-examined tracts, it enables us to understand more fully the cha-
