Each of these branches is a raceme, with the individual flowers arranged in pairs called exserted extending beyond the flower's tube form and one contained within the flower; all known examples of " P . atriplicifolia " in cultivation have exserted styles.

Those native to northern regions have small cones ( 1 3 cm ) with short bracts, with more southerly species tending to have longer cones ( 3 9 cm ), often with exserted bracts, with the longest cones and bracts produced by the southernmost species, in the Himalayas.
43.
Two species, " Benthamiella azorella " and " Benthamiella spegazziniana ", were at one time placed in a separate genus " Saccardophytum ", on the basis of two rather than five exserted stamens ( i . e . stamens appearing outside the flower tube ).
44.
It is a medium-sized evergreen cones are 4.5 7 cm ( rarely to 9.5 cm ) long and 2 3 cm broad, green or purplish ripening grey-brown, and often very resinous; the tips of the bract scales are slightly exserted between the seed scales.
45.
The cones are glaucous purple, maturing grey-brown, 6 15 cm long and 4 6 cm broad, with about 150 200 scales, each scale with a bract of which the apical 3 8 mm is exserted on the closed cone, and two winged seeds; they disintegrate when mature to release the seeds.
46.
The cones are erect, ovoid-conic, 4-7.5 cm long, with 50-100 seed scales, each seed scale with a long exserted and reflexed basal bract; they are dark purple when immature, turning dark brown and opening to release the seeds when mature, 5 7 months after pollination.
47.
"Salvia tiliifolia " grows up to tall, with broadly ovate and petiolate leaves, long and wide, that are slightly pubescent, with veins deeply recessed on the upper surface and exserted on the lower, with the margins finely and regularly crenate, bearing a strong resemblance to those of the " Tilia " or Linden tree.
48.
Another species, bristlecone hemlock, first described as " Tsuga longibracteata ", is now treated in a distinct genus " Nothotsuga "; it differs from " Tsuga " in the erect ( not pendulous ) cones with exserted bracts, and male cones clustered in umbels, in these features more closely allied to the genus " Keteleeria ".
49.
The Vietnamese population, with a disjunct range on Fansipan ( at 3, 143 m the highest mountain in Vietnam ), is distinct in paler red-brown shoots and the cones having shorter bracts ( not exserted ), and is separated as a subspecies " Abies delavayi " subsp . " fansipanensis " ( Q . P . Xiang ) Rushforth ( syn . " Abies fansipanensis"
50.
The 1-3 inflorescences are terminal, and peduncles 2.5-6 cm; the spathe is green, mucronate, 2-3.5 cm; the spadix is pale yellow to orange, constricted near the base, often exserted, stipe of about 4 mm; ovary is unilocular and uni-ovulate; fruiting spadix terminating in the male portion; berries red, roughly spherical, 10-12 x 8 mm.
