I know that in botany there is a wide classification for plants that can survive in hot deserts (semi-arid or arid) and harsh climates such as 4-season countries with a tendency to droughts each year (such as Palestine).
This classification, as I understand it, is thermophilic plants (hot loving).

But there is also the classification thermophilic plants which are also halophilic (salt loving), i.e. can survive and even flourish in extremely low and salty ground? Examples of such plants are found in the Ein Feshkha reserve near the Dead Sea in Israel and other similar Thypa and other plants reserves near the Dead Sea (current) shorelines in Israel, Palestine and Jordan.

Is there term for thermophilic-halophilic plants and if so, what is it?

Well, at least in other biological contexts, such organisms are often simply referred to as being thermohalophiles (or as being thermohalophilic).

Examples of the use of these words:

Bacteria:

  • Mavromatis, K., Ivanova, N., Anderson, I., Lykidis, A., Hooper, S.D., Sun, H., Kunin, V., Lapidus, A., Hugenholtz, P., Patel, B. and Kyrpides, N.C., 2009. Genome analysis of the anaerobic thermohalophilic bacterium Halothermothrix orenii. PLoS One, 4(1).

  • Denger, K., Warthmann, R., Ludwig, W. and Schink, B., 2002. Anaerophaga thermohalophila gen. nov., sp. nov., a moderately thermohalophilic, strictly anaerobic fermentative bacterium. International journal of systematic and evolutionary microbiology, 52(1), pp.173-178.

  • Pereira, M.M., Antunes, A.M., Nunes, O.C., da Costa, M.S. and Teixeira, M., 1994. A membrane‐bound HIPIP type center in the thermohalophile Rhodothermus marinus. FEBS letters, 352(3), pp.327-330.

Biochemistry:

  • Amoozegar, M.A., Salehghamari, E., Khajeh, K., Kabiri, M. and Naddaf, S., 2008. Production of an extracellular thermohalophilic lipase from a moderately halophilic bacterium, Salinivibrio sp. strain SA‐2. Journal of basic microbiology, 48(3), pp.160-167.

I'll note that I haven't found evidence of plants being referred to in this specific manner, but read the example papers below for use of the related phrases "thermohalophyte vegetation" and "thermohalophytes", respectively:

  • Accogli, R., Nutricati, E., Famà, L., Medagli, P., Manno, D., De Bellis, L., Marchiori, S. and Colasante, M., 2008. Iris revoluta Colas., natural hybrid origin species: characterization and preservation problems. Plant Biosystems, 142(1), pp.162-165.

  • Vekhov, N.V., 1996. Thermal and freshwater springs of the Chukchi Peninsula: Unique subarctic ecosystems. Part ii. flora. Polar Geography, 20(3), pp.209-220.

Is this word-blending approach the best or most appropriate? Couldn't say, but there is certainly prior precedence for combining the habit adjectives into "thermohalo-".
