Common Name The Knife-Shaped Leaf Angraecum
Flower Size 1.4" [3.5 cm]
Found in Kenya, Tanzania, Malawi, Mozambique, Zambia, Zimbabwe and Natal South Africa in dry evergreen forests and bushlands from sea level to 1800 [350 to 650] meters as a small sized, erect to pendant, hot to warm growing epiphyte with straight to curved, slightly 2 edged stems carrying 2 ranked, ligulate, falcate, very unequally bilobed apically, yellowish to pinkish green, sometimes dotted darker leaves that blooms in the fall and winter on a intervallatae [one per node], sometimes to 4, 1" [2.5 cm] long, single flowered inflorescence with lanceolate, acute floral bracts and carrying sometimes non-resupinate flowers.
"This species is clearly related to A stoltzii and it also shows affinity to A. erectum . From A stolzii it differs in the less elongated stem with much shorter internodes, the larger flowers and the relatively long slender spur which is only slightly thickened in the distal part. A erectum also has longer and more laxly leafy stems, but the flowers are even larger and white in colour, while the leaves are more distinctly bilobed at the apex. The leaves of A cultriformis are usually tinged with bronze or yellow bronze." Summerhayes 1958 The leaves in A. cultriform
