[R-sig-eco] plotting CCA results in vegan

Hello, I have two related questions:

1.) Is there a way to use ordipointlabel to jitter species names on a CCA plot AND get biplot arrows to be displayed as well? I tried


But biplot arrows came out as points instead (see attached file). 

2.) Can I combine the output of the above (assuming there's a way to do it) with ordihull, so that I have jittered species names, biplot arrows, and convex hulls around factor centroids all on the same figure??

A subset of my data is attached, and the model I'm using is this (with spp<-inv[22:37] and env<-inv[13:21]):


Thank you in advance.
