===Distribution & Habitat:=== The Newcastle Range, in north-east Queensland.<br/> Habitat is open woodland amongst granite outcrops; decomposed granite soil. </div> </div> <div class="row"> <div class="small-0 large-6 columns"> ===Description:=== ''Cycas cairnsiana'' is listed by David Jones (1981) as 1 to 5m tall, and in some areas this could well be. However, observations around Petford, Chillagoe and again at Dimbulah, describe the plants up to 2m only, with quite a stout caudex, swelling toward the base. Heavy crowns of glaucous blue fronds arching bow like from the apex of the caudex. The pinnae forming a deep vee along the length of the rachis. The leaf coloration persists on both surfaces, and the naked petiole below the pinnae having small teeth. Leaf fronds in plants were 1.5m, but in very large specimens not at present seen but often reported, could easily reach 2m long. Male cones were 20cm long, ovoid, and golden brown. Female simple cones, initially ferruginous, pubescent and with a narrow petiole terminating in a small toothed head. Ovules two to a megasporophyll. These are green at first, then blue green and when finally pendant, a shiny brown. When the new centre fronds arise, they are a light blue uncoiling from a rusty coloured rachis, and are quite eye catching. This plant has strong recurving margins on all the pinnules. Being not nearly as frost tender as others of its kind across the Top End, this should respond well to cultivation in cooler areas. This statement is made regrettably as in this country cultivation for landscaping projects could well be our only means to save them from eventual extinction. </div> <div class="small-0 large-6 columns"> [[File:Cycas_cairnsiana02.jpg|frame|Figure 2.
