The gumnuts are small, 4 to 6 mm long and 5 to 8 mm in diameter, with several exserted valves ( sharp wooden points emerging out of the top of the gumnut ).
32.
Female flowers are sitting within 2 opposite bracteoles, they consist of a hyaline perianth of 1 5 distinct, entire or lobed tepals, and an ovary with 2 filiform, slightly exserted stigmas.
33.
The cones are 10 16 cm long and 4 cm broad, with about 150 scales, each scale with an exserted bract and two winged seeds; they disintegrate when mature to release the seeds.
34.
The multiplicate columella and lack of a siphonal notch place it near " Cystiscus ", but the pyriform shape, exserted spire, denticulate lip, and fine axial costae render it distinct.
35.
The cones are 10 20 cm long and 4 5 cm broad, with about 150 200 scales, each scale with an exserted bract and two winged seeds; they disintegrate when mature to release the seeds.
36.
Corolla creamy yellow; tube 4-5.5 mm not exserted; upper lip 23-2.5 mm; lower lip 2.2-3.5 mm, the middle lobe shallowly notched.
37.
The flowers have numerous exserted ( i . e . protruding ) stamens ( > 2x as many as the corolla lobes ), and their filaments are sometimes connate at their base ( forming a short stemonozone ).
38.
There are five stamens, inserted on the base of the corolla, alternate with its lobes, exserted; filaments slender; anthers bright yellow, oblong, introrse, versatile, two-celled; cells opening longitudinally.
39.
Identification of the different species is based on the size and arrangement of the leaves, the size and shape of the cones, and whether the bract scales of the cones are long and exserted, or short and hidden inside the cone.
40.
The cones are dark purple-blue, 6 12 cm long and 3 & ndash; 4.5 cm broad, with numerous small scales and exserted bracts; they break up when mature at 6 8 months old to release the winged seeds.
