Hornstedtia reticosa VAL. n. sp. (Tab. 10, fig. 6—10). 



Rhizoma supraterraneum, baud alte elevatum. Caulis + 3-metralis. Squa- 

 mae basales caulem et apicem rhizomatis vaginantes transverse exsculpto-reti- 

 cuiatae, septis valde irregularibus angulatis et dentatis labyrinthoideo-confluen- 

 tës, partibus exsculptis transverse elongatis. Folia oblonga, brevi-acuminata 

 (500X100) basi in petiolum brevem (5—10 mm.) decurrentia, glabra, mar- 

 gine sericeo-ciliata, fuscescentia. Ligula parva (5 — 10 mm.), margine et apice 

 longissime lanuginoso-villosa. Vaginae squamis basalibus similiter sed multo 

 tenuius reticosae septa multo tenuiora et minus prominentia, exsculptiones pro- 

 fusiores striis longitudinaiibus magis conspicuis, vactu scabriuscuîae. Spicae 

 breviter (60 mm.) pedunculatae fusiformes, cum pedunculo 200 mm. longae. 

 Torus planus. Bracteae pedunculares et invoiucrantes externae ovatae et 

 ovato-oblongae, summae 90 mm. longae, apice late rotundato, subtruncato 

 et subemarginato, muçrone minuto terminali piloso fere per totam super- 

 ficiem marginibus 3 mm, latis rubris exceptis indumento brevissimo denso 

 sublaevi vestitae, hie inde poris exsculptis minutis rotundis et transverse 

 oblongis nunc sparsissime nunc densius, imprimis versus apicem conspersae. 

 Bracteae florales elongato-oblongae 100 mm. X 20 longus, apice biden- 

 tatus, dentibus sub apicem acutum spinulosis. Corollae tubus (?) mm. Limbus 

 bilabiatus ringens. Corollae lobus dorsalis late canaliculatus et basi leviter 

 inflatus 28 mm. longus, lobi anteriores basi labello subadnatae, illo paulem 

 4 mm. breviores. Labellum subgeneris. Stamen subgeneris 30 mm. longum. 

 Stylodia semicylindrica crassa 7 mm. long'a. Staminodiorum rudimenta nulla. 



The flowers resemble those of 77. scyphifera and more especially 

 those of H, paludosa, but the staminodial rudiments are wanting and the 

 flowers are much larger, the limb 1.5 times as long. 



The Padang specimens are a little different by the indûment of the 

 leaves and ligula, the midrib being villous and the small ligula not as 

 densely villous and in one specimen being glabrous. Many more species 

 of this genus vary in a same way.
