Translating lsystem rules to Houdini lilac

[Drunkenpanda 0]

Hello,

I’ve been trying to create a lilac flower l system.
And after some looking around I found a system describing it in
The Algorithmic Beauty of Plants
http://algorithmicbotany.org/papers/abop/abop.pdf
 

I am however unable to properly translate it into Houdini

Below is what I get when I basically copy and paste it and that looks nothing like the picture in paper.

92 Chapter 3. Developmental models
n=10, δ = 60◦
#include K /* flower shape specification */
ω : A∼K
p1 : A : * → [-/∼K][+/∼K]I(0)/(90)A
p2 : I(t) : !(t=2) → FI(t+1)
p3 : I(t) : t=2 → I(t+1)[-FFA][+FFA]
