Description
Appearance and leaf
Puya mirabilis grows as an evergreen, perennial herbaceous plant that reaches with inflorescence stature heights of 1 to 1.5 meters. She lives terrestrially and is somewhat xerophytic. Many leaves are in a rosette of leaves together without a tribe is formed. After semen and Kindel education the mother plant dies slowly.
The tough, parallel venation leaves are divided into leaf sheath and blade. The white to brownish, relatively thick, durable sheath is broad - ovate with finely toothed margins, with a length and a width of 3 to 4 inches. The leaf sheaths are preserved long and form a bulbous protective coating on the plant-based. The simple, early balding leaf blade is narrow - linear with long tapered at the top end with a length of 60 to 70 inches and a width at the Spreitenbasis of 1 to 1.5 inches. The leaf margin is rough, spiky cut. The lower leaf surface and the leaf surface is scaly pressed only on the lower half are gray.
Inflorescence and flower
For Puya species after a relatively few years inflorescence is formed. The upright, strong inflorescence stem has a length of 90 cm and a diameter of about 1 cm to a circular cross section. The initially green, but soon dried up bracts on the inflorescence stem are similar to the foliage leaves and spurred on the edge, the bottom long and beaten back and the upper erect and short, but are longer than the intervening intercepts. The upright, simple, so unbranched, loose grape-like inflorescence has a length of 30 to 50 centimeters and a diameter of 16 centimeters and some flowers. The early drying up, almost upright to spreading bracts are triangular, broadly ovate -elliptic with pointed upper end, acuminate with spiny margin and with a length of 3 to 4 centimeters shorter than the sepals, but longer than the pedicels. The 1.2 to 1.5 inches long flower stalk is initially almost upright and curves after pollination down.
The hermaphrodite flowers are in threes with a double perianth. The three green, gray scaly, relatively thick. leathery sepals are somewhat asymmetrical, about 5 to almost 6 inches long and about 1 inch wide and almost triangular with indistinct acute upper end. The three greenish- yellow, bare petals are about 10 inches long and about 2 inches wide and rotate the fading spiral one. The six free stamens have about 15 millimeters long, yellow anthers and are slightly shorter than the petals. Three carpels are fused into a semi superior ovaries.
Fruit and seeds
The capsule fruits contain many seeds. The small seeds are airworthy.
Occurrence
The home of Puya mirabilis are the Bolivian department of Cochabamba and Tarija and Argentine provinces of Salta and Tucumán. Puya mirabilis rocky slopes at altitudes between 750-2590 meters.
System
The first description was in 1906 under the name ( basionym ) Pitcairnia mirabilis by Carl Christian Mez in repertory specierum Novarum Regni Vegetabilis, volume 3, page 6 That with the collection number 2320 in the herbarium Berolinense deposited Holotypusmaterial was Karl Fiebrig ( 1869-1951 ) on February 4, 1904 collected at the Rio Bermejo in the province in the department of Tarija in Bolivia Arce. The new combination to Puya mirabilis ( Mez ) LBSm. was published in 1968 by Lyman B. Smith in Phytologia, Volume 16, Issue 6, p 461. Another synonyms for Puya mirabilis is Pitcairnia mirabilis var tucumana A.Cast. Because it differed from the nominate only by their natural height, but there are transitional forms in all sizes. The specific epithet mirabilis means "wonderful" and refers to the relatively large flowers.
Puya mirabilis belongs to the subgenus Puyopsis in the genus Puya.
Use
Puya mirabilis is one of the few Puya species that are cultivated in many botanical gardens and some private collections. The seeds germinate well, it is easy to maintain in bright places and also start to flower.
