There is no mention of the direction of prickles on the leaf edges in Stace (2010), but in my old 1962 edition of Clapham, Tutin and Warburg, the prickles are described as forwardly directed.
Good to know that one source does say the prickles are forward pointing which also ties in with the other photos I've looked at on I-Spot!
