[ES] Se presentaron 14 recolecciones de distintas Gagea del Hb. Jaca al III Congreso de Óptima en Madrid, intentando despertar el interés hacia un género tan interesante de nuestra flora. Las Arenaria aggregata-querioides, presentan incompatibilidad genética en su contacto entre Jánovas-Ainsa (Huesca), por lo que deben considerarse dos especies distintas, modificando el criterio expuesto en 1948 por nuestro gran botánico P. Font Quer. Se describen dos taxa nuevos: Gagea lutea subsp. orosiae P. Monts. y Teucrium pyrenaicum subsp. guarensis P. Monts., pertenecientes a la flora de las Sierras exteriores pirenaicas. Ampliamos la Arenaria querioides Willk. con subsp. querioides, subsp. cantabrica (F. Q.) P. Monts. stat. nov. & comb. nov., subsp. cavanillesiana (F. Q. & Rivas Goday) P. Monts. stat. nov. & comb. nov., subsp. racemosa (F. Q.) P. Monts. comb. nov. y subsp. oscensis (Pau) P. Monts. stat. nov. & comb. nov. También parece oportuno considerar A. leptoclados subsp. minutiflora (Lóseos) P. Monts. stat. nov. & comb. nov. como taxon muy característico del Bajo Ebro.
[EN] Some problems on Spanish Gagea are pointed out in this paper, so as on the genus Arenaria, mainly A. querioides, of Central Spain and allied taxa, which need a taxonomical revision. Gagea lutea subsp. orosiae P. Monts. and Teucrium pyrenaicum subsp. guarensis P. Monts. are proposed as new taxa. Modifications on Arenaria querioides Willk., subsp. querioides, subsp. cantabrica (F. Q.) P. Monts. stat. & comb. nov., subsp. cavanillesiana (F. Q. & Rivas Goday) P. Monts. stat. &*'comb. nov., subsp. racemosa (F. Q.) P. Monts. comb. nov. and subsp. oscensis (Pau) P. Monts. stat. & comb. nov., are made. Arenaria leptoclados subsp. minutiflora (Loseos) P. Monts. stat. & comb. nov. is proposed as new subspecies typical of Ebro Valley. All the material used for this paper is from JACA Herbarium.
