Inquiries concerning the latex within plants
I've been very interested in latex in some plants.
I'd like to know more on that,especially,why some family of plants have more chance to have latex?For example,the compositae family, and what's interesting here is that those having latex are those belonging to the Cichorioideae subfamily,in which all the petals are ligule,while in the other subfamily,the asteroideae,in which the fistulae are present,there's no latex!
Has the presence of latex here anything to do with the presence of fistulae?
There are other aspects about latex I'm wondering.
This is my first post,any comments will be appreciated!
