Notes on the Genus Justicia in Bolivia

In preparation for a full, annotated checklist and keys of Bolivian Acanthaceae major taxonomic notes on 28 species of Justida from Bolivia are presented together with incidental comments on numerous other species. Many of these species occur in the neighbouring countries of Peru, Brazil, Paraguay and Argentina. Information is placed in the systematic sequence presented by Graham (1988) and discussion is made with reference to the sections recognised there. 21 new species are described (Justicia adhaerens, J. arcuata,J. beckii,J. chapareënsis, J. chuquisacensis, J. dryadum, J. israelvargasii, J. kessleri,J. lutensis, J. megalantha, J. mesetarum, J. obovata, J. pluriformis, J. praetermissa, J. rhomboidea, J. squalida, J. steinbachiorum, J. umbricola, J. vernalis, J. yungensis and J. yuyoënsis), a new name (J. rubriflora) is coined for Jacobinia glaziovii, two new combinations are made (J. albadenia and J. tenuistachys), subspecies are recognised and described for J. aequilabris, J. boliviana, J. kuntzei and J. tocantina, a.nd J. lilloi is shown to be an extreme variant of J. thunbergioides. The paper is illustrated with line drawings, SEM photos of pollen and a table.
