Hey Folks,
The March issue has been mailed. Any comments on the content? The cool article on CP in the UK (December 2006) will be hard to beat, but maybe you'll find things of interest here!
Cheers
Barry

My CPN arrived here in the UK this morning too. Nice to see Pings on the cover and a nice article by Oliver Gluch on P. chilensis inside. I've read most but I'm saving the technical paper on Drosera structures and phylogeny until my next bout of insomnia - I'm sure it will be therapeutic! Only joking!  Vic |

got mine today in Canada. Intesrestingly, I'm doing a survey of the importance of mycorrhizae association in terrestrials orchids for one of my course and this question came to my head: "And what about CP? Can their coarse, often scarce roots system supplied by such association?"
Well, one week later, i got a partial answer to my question! very interesting! ;D
Love that P. chilensis in bloom too!

Hello,
Just some comments on the article about mycorrhizal state of D. peltata:
There are only very few herbaceous plants that form an ectomycorrhizal association (EM). Generally, this type of mycorrhizae is restricted to trees. Exceptions of herbs with EM are a few Cistaceae, Rosaceae and Polygonaceae, in all of them with herbaceous perennial plants, that have a persistent rhizome and strongly developed, thick roots which can support ectomycorrhizae. The listing of Stylidium amoung plants with EM is resulting from the fact, that some triggerplants form a mycorrhizal association with so called "dark septate hyphae", a mycorrhizal type that still is not understood well (but clearly distinct from EM). Most herbaceaous plants (with thin roots) form an endomycorrhizal assiociation (this means that the fungal partner's hyphae are penetrating the root cells of the host plant), a so called arbuscular mycorrhiza (AM).
Thus I really doubt that any species of Drosera can from an ectomycorrhizal association.
The cited paper of Fuchs & Haselwandter refers to AM only, thus is no support for the author's hypothesis.
The identification of the fungus partner is doubtfull as well. If I got it right, they identified a Suillus luteus as mycorrhizal partner from spores found in nearby soil. Well, almost all members of Boletaceae (or Suillaceae), where Suillus belongs to, have more or less elliptical brownish hyaline spores. Nevertheless, the site was close to a pine forest, and Suillus prefers mycorrhiza with Pinus trees.
All the best,
Andreas

i still havent gotten mine I've found it is quite natural for there to be a few weeks spread between the first person and last person in the USA to get their issue. There's even more dispersion for members in the rest of the world. All I can say is to sit on your hands for a week or so. You should get it soon. B |

Hello all,
First
Good work to all involved in the March issue (36:1)!
After reading Barry Rice's article (great article Barry) about hybrid trapping mechanisms and looking at some of my Dionaea, I have started to wonder if many carnivorous plants became carnivorous more to avert insect damage, than to supplement nutrients?
There are numerous examples in nature of plants that have developed defense mechanisms, and are not carnivorous at all, I know.
My Dionaea developing multiple traps per leaf because of mealybug damage, is very much like swatting flies with a hammer, (a better analogy would be to use two or three hammers because one did not work) but over time some additional mutation could become successful for protection for this genus against small pest insects.
Just wanted to let you know your article got my imagination going! Thanks!
Steven Stewart
