Etymology:— ” umidicola ”, from Latin, inhabits in wet places; “ jorgenseanus ” in homage to Jörgensen a botanical explorer in Argentina who collected the type specimen; “ catamarcensis ” a Latin version of the province where the type was collected; “ divorsus ” from Latin “ diversus ” used by Smith for his interpretation of the eccentric arrangement of leaflets in the petiole, a character perhaps due to growth after grazing damage. “ tucumanensis “ is a Latin version of the province where the type was collected.
Phenology:— Following the records of the collected specimens and observation on the field the plants regrow from the caudex in early spring and start blooming in Summer (January) that extends to middle February where the plants are with flowers in apical branches and fruits on the basal branches. Fruiting extends to March-April.
Distribution, Habitat and Red List of Endemic Species Category:— It is a variety distribute on the intermontane valleys and on a small portion of the High Montane Ecosystem of NOA provinces of Jujuy, Salta, Catamarca and Tucumán. In Córdoba it was collected in the summits of the Sierras de Comechingones belonging to the cordons of the Sierras Grandes included within the Departments of Calamuchita to the northeast, San Javier to the west and Río Cuarto to the South (Fig. 4 D). It grows on steep slopes in wet valleys and stream banks between grass and other small herbaceous vegetation in sunny and moist places. In the vascular plants of Sierra de Famatina (La Rioja) this species as L. umidicola was cited as life form chamaephyte and status native in Puna Altoandina (Barboza et al. (2016). The first collection record was in 1879 in La Rioja and the last in 1998 in Salta. Although it has a wide range of distribution in relation to the other varieties, more than 23 years have passed without any record of herbarium collection, in areas of frequent botanical expeditions. The lack of recent herbarium specimens could be related to the loss of population in places affected by climatic variabilities severe droughts, such as those indicated in L. burkartianus, or by wild herbivorous predators or domestic horses that have been seen grazing in the Enchanted Valley in Salta. Therefore, droughts and herbivores make it more difficult for plants to recover after losing vegetative and reproductive organs. This variety as specie level (L. umidicola) was assigned in 2010 the conservation status of Category 3 (PlanEAr, 2021), however considering all the negative factors that are affecting the area of distribution, this author assigned the variety, for first time, to Category 4 following the scale of PlanEAr and VU (Vulnerable) under the IUCN status.
Comments:— The description L. jorgenseanus was based solely on the holotype specimen Jörgensen 1122 at DS, as was explained above the Jörgensen collection with the number 1122 or without numbers were distributed by the curators of LIL to different herbaria with specimens bellowing to different taxa. Consequently, only the specimens at DS and at LIL should be considered holotype and isotype of L. jorgenseanus. One specimen at BA collected on the same place and with the same collector number but on 3 Feb. 1916 could be a cotype of L. jorgenseanus which is a synonym of L. austrorientalis var. umidicola. The other specimens Jörgensen 1122 or Jörgensen wthou/# at GH, MO and US that were cited by Smith as paratypes of L. lilloanus are treated here as representatives of L. hieronymi.
The holotype of L. schickendantzii from B herbarium was lost on the WWII fire, the isotype at CORD is a young plant with the inflorescence not elongated, however C. P. Smith (Sp. Lup. 352, 1944) described the characteristics of the fruit. Considering that, usually the institute that donate specimens always keep the best samples for the own collection it is very improbable that the specimen at B were a mature plant with flowers and fruits, consequently, Smith probably described the pod from the paratype Hieronymus 645 at K that is bearing flowers and fruits.
“La Queñoa”, which was indicated as a place of collection L. tucumanensis by Rodríguez in 1912, does not appear as a town or place on past and current maps of Tucumán. It is possible that queñoa means an area where grows Polylepis australis Bitter, a native tree from the Mountain Forest of Tucumán above 2000 m s.n.m. whose common name is queñoa.
Seed samples of this variety under the name L. umidicola was part of analyses of sterol and fatty acid patterns (Fuentes & Planchuelo, 1999) crude protein, crude oil, fatty acid and seed flour thermic properties (Differential Scanning Calorimetry). Moreover, leaves and photosynthetic stems were analyzed for flavonoid profiles (Fuentes & Planchuelo, 2006). Also, this variety was part of a phylogenetic study on representative species of Old World and New World by nucleotide sequences from rbcL and ITS 1+2 gene, (Merino et al., 2000) and molecular evolution of Lupinus (Wink et al., 2000).
