2 Four new species of Lepanthes Sw. from Costa Rica Carlyle A. Luer MD & Johan Hermans Figs 4 1 and 42. Lepanth es clareae Luer & Herm ans sp. nov. Abstract Although the flora of Costa Rica has bee n studied intensively by seve ral institutions and resea rchers for the past century and a half, new species of the pleurothallid ge nus l epanthe s are continu ally being reco gnized. Prior to the prese nt four new spec ies disco v ered rece ntly by Joh an Herman s and his wife Dr Clare Herm ans, approximately 60 species of Lepanthe s were known from that small, Central American countr y. Three of the new specie s are des cribed from plant s that have flowered in cultivation by the Hermans in Crews Hill. Another of these new species has also been discovered by Steve and Karen Ingram of Bishop, California. The following species are member s of subsection Lepanthes distinguished by congested racemes shorter than the leaf. 3mm 2mm ~ w 5 cm..,., Lepanthes amplectens Luer & Hermans, sp. nov.

7 Elena near the Monte, erde Re:-.nve, alt. l, 00m, flowe red in culti, ation 12 Jan I c- C H er111a11 s.!5 77 (K. MO). This species is distinguished bv the large habit with black sheat hs of stout ramicauls. The flowe r is held from the distichous race me by a long ovary. The sepals are yellow, broad ly ovate and shortly acumin ate. The petals are red, tran sverse and ob tuse. Most distinctive is the thick. protruding body of the lip with broad co nnect ives that bear smaller blades to either side of the column. The small, bifid appendix is borne externally on the foiwa rd surface of the protruding bod y. Lepantbes Jerrellia e is similar to the widely distributed, Central American L. disticba (A. Rich. & Galeotti ) Garay & R. E. Schult, but the latter is distinguished by the large, protub erant. body of the lip. Lepanthes hermansii Luer, sp. nov.

Photogra phy by Johan Hermans Etymology : Named in honour o f Jo han Herm ans o f Crews Hill, Middl e sex, England, co-discoverer o f thi s species. Thi s species is distin guished by the medium -sized habit with ellipti cal leaves borne by ramicauls with close, glabro us sheath s; a co ngested, lo ngpedi cellate raceme; and tri angular, acute, carin ace, denti culace sepals. Th e lobes of th e petals are obliqu ely tri angular, the lower lob smaller and diverging. Th e oblong blade of the lip are shorter than the column, the apices produced by the prolonged tip s of the connectives. Th e body is sho rt with a broad sinu s with out an appendix. Lepanthes hemwn sii with the obliqu ely tri angular lobes of the petals is simil ar co Cosca Rican L. glicenstei11ii Luer, but th e latt er is di stin guished by entir e sepals and ch presence of an append ix.
