Nepenthes. 6 [ 



Nota. Species haec nova mihi solum nota est e speciminibus a cl. Teysmann lectis. 

 Descriptionem dedi secundum exemplaria mihi a cl. Treub sub nom. »N. Rafflesiana Jacke 

 missa, a qua species facile dignoscenda est foliis angustis attenuatis, nervatura, colio aseidii 

 nullo, forma et latitudine peristomii, et operculi struetura glandulosa.

 lata, membranacca v. subherbacea, petiolata; petiolus 5 — 10 cm longus, tenuis, alis 

 angustis, ad Y 2 — 2 /3 amplexicaulis, basi non v. ± decurrens; lamina lafticeolata, basi 

 et apice gradatim attenuata, glabra, nervi longitudinales in paria 5 rarius 4 dispositi, 

 omnes a basi folii Orientes, par intimum 5 — 8 mm, par secundum 8 — 12 mm, par 

 tertium 10,5 — 15mm, par quartum 13 — 18mm, par quintum 15 — 21 mm a costa 

 remotum, nervi transversi ascendentes paralleli ± sinuosi, 4 — 5 mm separati; cirrhus 

 35 — 45 cm longus gracilis versus basim aseidii recurvatum ampliatus; aseidia 12 — 

 2 cm longa X 2 — 2,5 cm lata, membranacea, sparse stellato-pubescentia et brunneo- 

 punetata, sub peristomio tomentosa, dimorphia; aseidia inferiora subeylindrica, vix v. 

 =b a basi ad os angustata, alae ventrales basi ampliatae, os versus gradatim angustatae, 

 ciliatae; aseidia superiora infundibuliformia a basi os versus gradatim ampliata, dein 

 leviter contraeta, alae ventrales ad nervös prominentes reduetae, os circulare obliquum 

 postice in Collum angustum 2 — 3 cm altum elevatum; peristomium 5 — 12 mm latum, 

 antice cylindricum aequale, aliquanto angustum margine interiore pectinatum, postice 

 sursum in collum forma jugorum duorum latorum convergentiüm pectinatorum amplia- 

 tum; operculum 3,5 — 4 X 2,5 — 3 cm latum membranaceum, cordato-triangulare, in 

 medio valde binervium nervis minoribus lateralibus, extus glabrum, intus glandulis fere 

 aequalibus dispersis obsitum; calcar 10 — 12 mm longum, gracile, attenuatum; aseidium 

 intus per dimidium superius v. profundius glaueum, opacum et deducens, inferne nitidum 

 glandulosum et detinens. Flores et fruetus ignoti.

Sumatra?: (Korthals!, speeimen in Herb. Kew. nomine — fide Blume — 

 N. Rafflesiana designatum, et sub nomine JV". Rafflesiana var. glaberrima Hook. f. in DC. 

 Prodr. descriptum). 



Nota. Species' haec adhuc confusa est cum N. Rafflesiana, cui similis est petiolo longo 

 et peristomio elongato pectinato. Differt nervis foliorum, cirrho longo gracili, aseidiis angustis 

 elongatis, operculo cordato glandulis diffusis, superficie deducente profunda. In Herb. Kew. sunt 

 exemplaria separata, in Herb. Mus. Brit. et in Herb. Harv. singula. Haec omnia cum N. Raf- 

 flesiana var. glaberrima Hook. f. congruere videntur.
