Agave parryi

Agave parryi is a species of the genus Agave ( Agave ).

Description

Agave parryi growing singly or forming large, compact groups with stature heights of 20 to 30 cm and 30 to 80 in diameter. The green arranged variable, stiff or curved, lance-shaped leaves linealischen up with the sharp, gray to brown Enddorn are 20-30 cm long and 15-20 mm wide. The fibrous leaf margins are finely serrated irregular near the base.

The Rispige inflorescence is 3 to 5 m high. The yellow -colored flowers appear at the top of the inflorescence at the end of the branches and are 60 to 75 mm long.

The ovoid to elongated dreikammerigen capsule fruits are 35-50 mm long and 15-20 mm wide. Black, irregularly shaped seeds are 7-8 mm long and 5-6 mm wide.

The flowering period is from June to August.

Systematics and distribution

Agave parryi grows from Central Arizona and southwestern New Mexico in the United States to Mexico in the states of Chihuahua and Durango and on stony slopes in grasslands, in open woodlands in 1500-2500 m altitude. It is associated with a variety of cacti and succulents -.

The first description by George Engelmann was published in 1875. One of the numerous synonyms Agave parryi var applanata

We distinguish the following subspecies and variety:

  • Agave parryi subsp. parryi
  • Agave parryi subsp. neomexicana
  • Agave parryi var cousii
  • Agave parryi var huachucensis
  • Agave parryi var truncata

Agave parryi is a member of the group Parryanae with the largest area of ​​distribution within the group, which extends from central Arizona to Mexico. Remarkable are the single or compact, globular, group-forming plants with gray to green, stiff, smooth linealischen to egg-shaped upturned leaves with the sharp, needle-like Enddorn. The red-brown leaf margins are irregularly toothed. The Rispige, straight, 3 to 5 m high inflorescence forms in the upper half 12 to 15 irregularly long branches. The flowers are yellow to orange. The various subspecies and varieties differ in size, leaf and flower structure. Agave chrysantha and Agave hybrids with schottii are known. Agave havardiana is closely related, however differences in leaf structure can be seen.

The subspecies parryi subsp neomexicana and the variety cousii can survive down to minus 20 ° C in dry state periods of frost.
