Conservation
Endangered (EN), B1 a,b (i,ii,iii,iv); extent of occurrence = 1672 km2. Despite its rather wide extent of occurence, the known populations are found in areas of Atlantic forest near expanding towns or, in the case of the Represa do Grama, near aluminium mining. In Rio de Janeiro, it is protected within the Parque Nacional da Floresta da Tijuca and in the Reserva Biológica do Tinguá.
Distribution
Southeastern Brazil, Minas Gerais and Rio de Janeiro states.

Morphology Leaves Petiole
Petiole 13.5 - 46 cm long
Morphology Leaves Prophyll
Prophyll 18-25.5 x 4-5 cm, narrowly triangular, pale green

Note
Sakuragui & Mayo (2005) give a more detailed treatment of the nomenclature and taxonomy of this species. Philodendron hastatum shows wide morphological variation, particularly in leaf shape. Despite this, the leaf characters are useful for distinguishing the species, in particular the extrorse lobes of the posterior divisions and the very elongated anterior division. This latter feature brings it close to P. curvilobum, but this species, unlike P. hastatum, has a long-cuspidate leaf apex.
Phenology
Flowers from August to December. Immature berries were found in December.
Type
Cultivated plant at Berlin Botanic Garden (Bf). Neotype: specimen of original provenance, "Hort. Schoenb. in Hb. Schott 1859" (K! ), determined as Philodendron hastatum K. Koch in H. W. Schott's handwriting, and annotated: "Philodendron hastatum K. Koch, specimen compared to the type in Koch's herbarium by N. E. Brown 1878" (K).
