Família: 

Bignoniaceae

Nome científico: 

Pithecoctenium crucigerum

Descrição Morfológica: 

Trepadeira lenhosa que chega a formar tronco (cipó) com 5 a 10 cm de diâmetro. Pode ser mantida sob a forma de arbusto através de podas. Suas folhas são opostas e compostas trifolioladas, sendo que muitos casos o terceiro folíolo ocorre na forma de uma gavinha. Os folíolos são ovados, glabros, com cerca de 15 cm de comprimento por 8 a 10 cm de largura.

Flores e Frutos: 

As flores tubulosas de cor branco-amarelada, com cerca de 5 a 7 cm de comprimento. Floresce principalmente na primavera e no verão. Os frutos são secos e deiscentes, com a parte externa coberta por espinhos grossos, o que lhe confere a denominação pente-de-macaco. Os frutos em geral amadurecem no final do verão. As sementes são aladas.

Características Ecológicas: 

Heliófita comum em clareiras e bordas de floresta formando, junto com outras lianas, redes de proteção à comunidade florestal. Em geral os indivíduos antigos se alastram pela copa das árvores.

Ocorrência Natural: 

Existem registros em diversas regiões do Brasil, mas é efetivamente comum de Minas Gerais até o Rio Grande do Sul. No Paraná ocorre na região planáltica, dentro das Florestas Ombrófila Mista e Estacional Semidecidual.

Usos: 

Se bem conduzida pode ser usada como planta ornamental, valorizando suas flores e folhas exuberantes. Pode também cumprir função importante na restauração vegetal de taludes íngremes, formando redes de retenção de umidade e matéria orgânica. Por fim, seus frutos são utilizados na confecção de artefatos artesanais como colares e móbiles.

Aspectos de Cultivo: 

A germinação ocorre poucos dias após a semeadura, sendo a taxa germinativa relativamente elevada.
