Nepenthes alata

***Nepenthes alata*** (; Latin: *alatus* "bersayap") adalah tumbuhan kantong semar yang endemik di Filipina.

*Nepenthes alata* telah lama diperlakukan sebagai spesies yang sangat polimorfik mencakup semua pulau-pulau besar kepulauan Filipina (dengan kemungkinan pengecualian Palawan). Di bawah batasan yang luas ini, *N. alata* dipahami memiliki berbagai ketinggian dari 0-1.900 m (0-6.234 kaki) di atas permukaan laut dan tercatat dari, antara lain, pulau Bohol, Camiguin, Cebu, Culion, Leyte, Luzon, Mindanao, Mindoro, Negros, Panay, Samar, dan Sibuyan. *Nepenthes alata* dalam arti luas ini (*[[sensu lato]]*) merupakan salah satu *[[Nepenthes]]* termudah dan paling populer untuk dibudidaya.

Pada tahun 2013, *N. alata* kembali dibatasi oleh Martin Cheek dan Matthew Jebb yang mencakup hanya populasi dari utara dan tengah Luzon dengan kantong berbulu mencolok (takson dikenal di kalangan hortikultura sebagai "*N. alata* berbulu"). *N.&nbsp;alata* *[[sensu stricto]]* Cheek dan Jebb memiliki penyebaran ketinggian di atas 550 m (1.800 kaki). Berdasarkan penafsiran ini, tumbuhan di selatan yang sebelumnya disebut spesies ini ternyata benar-benar mewakili *[[Nepenthes graciliflora|N. graciliflora]]* baru dikeluarkan (hortikultura "*N. alata* khas"; ditemukan di Bohol, Leyte, Luzon, Mindanao, Mindoro, Panay, Samar, dan Sibuyan) serta *[[Nepenthes negros|N. negros]]* baru dideskripsikan (Biliran dan Negros) dan *[[Nepenthes ramos|N. ramos]]* (Mindanao). *[[Nepenthes viridis]]* dari Dinagat dan Samar merupakan kerabat dekat lain, seperti *[[Nepenthes ceciliae|N.&nbsp;ceciliae]]* (Mindanao), *[[Nepenthes copelandii|N.&nbsp;copelandii]]* (Mindanao), *[[Nepenthes extincta|N.&nbsp;extincta]]* (Mindanao), *[[Nepenthes hamiguitanensis|N.&nbsp;hamiguitanensis]]* (Mindanao), *[[Nepenthes kitanglad|N.&nbsp;kitanglad]]* (Mindanao), *[[Nepenthes kurata|N.&nbsp;kurata]]* (Mindanao), *[[Nepenthes leyte|N.&nbsp;leyte]]* (Leyte), *[[Nepenthes mindanaoensis|N.&nbsp;mindanaoensis]]* (Dinagat dan Mindanao), *[[Nepenthes saranganiensis|N.&nbsp;saranganiensis]]* (Mindanao), dan *[[Nepenthes ultra|N.&nbsp;ultra]]* (Luzon). Bersama dengan spesies ini, membentuk apa yang disebut "kelompok *N. alata*", yang disatukan oleh sejumlah karakter morfologi, seperti tangkai bersayap, tutup dengan rabung pangkal pada permukaan bawah (sering dijabarkan sebagai alat pelengkap), dan kantong atas yang biasanya meluas di dekat dasar.

## Deskripsi
Rumus floral untuk bunga jantan adalah ✶ K4 A4+4+1* G0 (mungkin tidak terdapat benang sari apikal /*/) dan ✶ K4 A0 G(4) untuk bunga betina.

## Taksonomi
*Nepenthes alata* berkaitan erat dengan beberapa spesies lain, termasuk *[[Nepenthes copelandii|N. copelandii]]*, *[[Nepenthes mindanaoensis|N. mindanaoensis]]*, dan *[[Nepemthes saranganiensis|N. saranganiensis]]*. *[[Nepenthes eustachya]]* dari Sumatra pernah dianggap termasuk ke dalam variabilitas *N. alata*, tetapi didasarkan pada jenis spesimen salah tafsir, dua spesies ini tampaknya tidak terkait erat satu sama lain.
