S. alata "areolata"

Ciao, come da titolo cerco questa pianta, chiunque ne abbia una, o una divisione mi faccia sapere. Posso scambiare con altre sarre o pagarla.

E che pianta sarebbe la S. alata "areolata"?? hai qualche foto oppure qualche indicazione o un codice di una pianta che hai visto da qualche parte??
Areolata è un ibrido leuco x alata se non mi sbaglio e potrebbero esserne a decine differenti fra di loro, sopratutto nelle collezioni inglesi.

Areoles are commonly known in S. Ieucophylla, S. psittacina and S.minor and have been noticed by Case and Case (1976) in S.alabamensis ssp. alabamensis and in S. rubra ssp. Jonesii and S. rubra ssp. rubra by Schnell (1977,1990). The Cases (1974) notes that the areoles in S. alabamensis ssp. alabamensis are " . . . the consequence of the extreme tissue expansion characteristic of the summer pitchers. They are not structurally quite the same as in the truly areolate species." Areoles on S.alata in Texas and western Louisiana are similar to those in S.alabamensis ssp. alabamensis, although not confined to summer leaves but produced on leaves throughout the season. A comparative picture of pressed fall leaves of S. alata and S. alabamensis ssp. alabamensis from cultivated material demonstrates the similarity of the areoles in both species (Figure 6).

Hybridization often occurs between S. alata, S. psittacina and S.Ieucophylla in Alabama and Mississippi where the pitcher plant species ranges overlap. One of the results of this overlap in range is introgressed S. alata with areoles. Whether any of these areolate plants are pure genetic forms and not introgressed hybrids must await further analysis. Introgression, however, appears unlikely to be a factor in the presence of areoles in the Texas and western Louisiana range of S.alata since McDaniel (1966) noted that particular components found in introgressed S.alata were not found in areas where hybridization is improbable. Hybridization between S.alata and any other sarracenia is highly improbable in Texas and western Louisiana since no other pitcher plant now naturally grows in these areas. Thus it appears the presence of areoles in Texas and western Louisiana plants is an inherent feature of the species and not the result of recent introgression with areolate species of sarracenia. Ancient introgression between S.alata and areolate sarracenia cannot be eliminated as a factor in present-day S. alata without chemical, paleobotanical and phytogeographic evidence.

It should be emphasized that the occurrence of areoles in plants of Texas and western Louisiana S. alata stations is a feature which may be enhanced by environmental conditions. Burning of a S.alata bog in Beauregard Parish in 1989 demonstrated this point. A site for S.alata in Beauregard Parish, Louisiana was visited in both June of 1988 and 1989. Although areolate pitchers were sought in 1988, none were seen. Many pitchers were damaged by an Exyra larvae infestation which could have obscured the presence of windows. Areoles were observed in great numbers of plants in June 1989 several months after a fire. Apparently the improved growing conditions provided by fire and suppression of Exyra larvae aided the production of areoles. It should be noted that this bog in Beauregard Parish, Louisiana possess a large, naturally open area. This area in June of 1988 was not noted to contain any obvious areolate plants but did contain them in 1989. The effect of fire, even on an open area, may have been enough to produce areoles. Conceivably the suppression of Exyra larvae by fire played a role in reducing insect damage to pitchers and enhancing areole production.

Pipeline hillside seepage bogs in Jasper County, Texas also illustrate environmental conditions enhancing areole production. Areoles were observed in a Jasper County, Texas pipeline hillside seepage bog in both 1988 and 1989. The site is maintained in a very open condition by annual mowing of the pipeline right-of-way. These annual mowing provide open habitat and allow dense stands of S. alata to develop. Fire would naturally maintain the hillside seepage bog in an open condition, but in this instance the pipeline has substituted as a disturbance factor. Mechanical clearing by bushhogs simulates the effect of fire by inhibiting the growth of woody plants. The suppression of woody plants allows herbaceous types to flourish. Thus, disturbance of hillside seepage bogs may enhance areole production in S. alata by providing open growing conditions.

Cmq sono forme di alata tipiche del Texas in particolare

ciao!!!

guarda qui: areolata

Due anni fa Furio mi ha venduto una S. x 'areolata' (S. leuco bianca x S. alata "giant"-----questo è quanto riportato sul cartellino), ma purtroppo si è ammalata e sono riuscito a salvarne solo 3 cm di rizoma.....speriamo si salvi, ma dato il periodo la vedo dura.

L'ibrido S. x areolata è una cosa diversa dalla S. alata "areolata", che pare sia una alata non ibridata.

Ok, buono a sapersi...infatti dalle foto non mi sembrava per niente la mia.

Hai ffz.
