It produces flowers and fruits throughout the year except in August and September.   Conservation status The assessment was based on 16 collections representing 11 localities and resulted in an EOO of 642 km 2, an AOO of 44 km 2, and eight subpopulations representing six locations, of which three occur within protected areas (Andavakoera-Andrafiamena-Ambohipiraka and Ankarana). Areas not benefiting any form of protection exhibit continuing decline in habitat quality, EOO, AOO and number of mature individuals resulting from conversion of forested land into agricultural fields and pastures, and wood harvesting. Therefore,  N. longipedicellatais assigned a preliminary status of “Vulnerable” [VU B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v)].   Notes   Noronhia longipedicellatacan be recognized by its coriaceous, obovate leaf blades with barely visible venation, long pedicels, and orange-purplish flowers.   Additional specimens examined   MADAGASCAR. Prov. Antsiranana: Ambilobe, AnkaranaRS, 13°01’26”S 49°05’33”E,  32-143 m,  16.IV.1996,  Andrianantoanina& Bezara964( K, MO, P);  ibid. loc., [ 12°49’S 49°01’E],  6.X.1990,  Bardot-Vaucoulon104( P);  Andrafiamena, Anjahankely, 12°55’38”S 49°17’34”E,  510 m,  12.XI.2010,  Gautier5415( G, K, MO, P, TEF);  Marivorahona, Betsimiranja, 12°56’27”S 49°07’21”E,  136 m,  17. I.2009, Hong-Wa 564( MO, P, TAN);  ibid. loc., forêt d’Ambilomagodra, 13°01’24”S 49°08’07”E,  58 m,  30. I.2009, Hong-Wa et al. 592( MO, P, TAN);  Anivorano-Nord, Andrafiabe, Mt Antsahabe, 12°54’59”S 49°17’38”E,  502 m,  3.VII.2010, Hong-Wa 715( MO, TAN);  Marivorahona, Betsimiranjana, Ankarana, 12°57’32”S 49°07’12”E,  132 m,  8.XII.2006,  Ranaivojaonaet al. 1665( CNARP, MO, P, TAN);  Mosorolava, Ampombiantambo, 12°41’24”S 48°56’59”E,  75 m,  27.IX.2007,  Ratovosonet al. 1381( CNARP, MO, P, TAN);  ibid. loc., forêt d’Antsoroby, 12°40’29”S 48°58’52”E,  23.IX.2007,  Razafitsalamaet al. 1231( CNARP, MO, P, TAN);  PK 95sur la route de Diégo-Suarezà Ambilobe,  13.IV.1954,  Service Forestier9725( P, TEF). 4023240829 M de l'Ankarana Prov. 154 154 1 Antsiranana holotype 4023241023 [605,1277,652,679] 1937-12 S 250 -12.9 d'Ampasimbengy 1292 49.133335 154 154 1 Antsiranana holotype 4023240664 1938-01 I, P Humbert 154 154 P00573412, P00573413 1 Antsiranana holotype 4023241062 1996-04-16 K, MO, P Andrianantoanina & Bezara Madagascar Prov. 88 -13.023889 Ankarana 21 49.0925 Ambilobe 155 155 1 Antsiranana 4023240742 1990-10-06 P Bardot-Vaucoulon Madagascar Prov. 88 -12.816667 Ankarana 1292 49.016666 Ambilobe 155 155 1 Antsiranana 4023240790 2010-11-12 G, K, MO, P, TEF Gautier Madagascar 510 -12.927222 Anjahankely 21 49.292778 Andrafiamena 155 155 1 4023240716 2009-01-17 I, MO, P, TAN Madagascar 136 -12.940833 Betsimiranja 21 49.122498 Marivorahona 155 155 1 4023240425 2009-01-30 I, MO, P, TAN Madagascar 58 -13.023334 d'Ambilomagodra 21 49.13528 Marivorahona 155 155 1 4023241254 2010-07-03 MO, TAN Madagascar Anivorano-Nord 502 -12.9163885 Mt Antsahabe 21 49.293888 Andrafiabe 155 155 1 4023241389 2006-12-08 CNARP, MO, P, TAN Ranaivojaona Madagascar Marivorahona 132 -12.958889 Ankarana 21 49.12 Betsimiranjana 155 155 1 4023240575 2007-09-27 CNARP, MO, P, TAN Ratovoson Madagascar 75 -12.690001 Ampombiantambo 21 48.949722 Mosorolava 155 155 1 4023241456 2007-09-23 CNARP, MO, P, TAN Razafitsalama Madagascar 75 -12.674723 d'Antsoroby 21 48.981113 Mosorolava 155 155 1 4023241486 1954-04-13 P, TEF de Diego-Suarez & Service Forestier Madagascar Ambilobe 155 155 PK 95 1
