- A cauliflorous branch with both male spike-like strobiles (microsporangiate axes) which with both invisible peduncles borne within a cupular bract of swollen node, upper portion of bract broken, about 1.8 mm high, 4.2 mm wide, cauliflorous branch 2.3 mm long and 0.9 mm wide, spikes with numerous verticillate annular involucral collars, apex conical point. Large strobile with about 23 whorls of involucral collars in preservation, base slightly narrow and slightly broadish upward, apex somewhat broken, 6.8 mm long and 2.4 mm wide in widest part, margin entire and somewhat undulate. Microsporangiate units (male “flowers”) indiscernible within involucral collars, their number and arrangement unknown. Small strobile with about 17 whorls of involucral collars in preservation, base obtuse and apex partially broken, 5.5 mm long and 1.5 mm wide in preservation, margin entire and slightly undulate. Microsporangiate units within involucral collars indiscernible, their number and arrangement unknown.
