ò. triflora, Linn. (sp.) Mant. Plant. p. 240 (1771). 
Linneus gives a clear and full description of this plant in the 
second portion of his ‘Mantissa Plantarum’: Caules palmares, 
copiosi, diffusi, adscendentes, teretes, subpubescentes: ramis 
alternis erectis. Folia lanceolato-subulata (juniperina), patentia, 
acuminata, ciliata, subtus pubescentia: floralia ovato-lanceolata, 
Subtus pilosa. Pedunculi terminales, plures, teretes, pubescentes, 
articulis caulinis longiores, triflori ; pedicellus intermedius 
aphyllus, laterales longiores ; bracteis duabus, ovatis, ciliatis, 
extus pubescentibus. Calyx ovatus, acutus, erectus, pubescens. 
Petala obovata, oblonga, ealyee duplo longiora, patentia, obtusa, 
alba, lineata. Stamina alba. Pistilium viride staminibus brevius. 
The following more or less intergrading forms of this variety 
are worked out from the material in the Vienna Herbarium, 
consisting of the specimens from Fenzl's own herbarium. They 
differ in minor details when placed side by side, but are rather 
difficult to separate satisfactorily by definition :— 
Lusus 1 (parviflorus). Humilis. Confertim et pulvinatim 
cespitosa, caudiculis lignescentibus. ^ Caulieuli 1-3-flori 
stricti 12-35 mm. Folia imbricato-congesta, erecta vel 
patula, anguste subulata. Calyx 3 mm.
