Discussion:This species has generally been misidentifled as T. formosa (Cham. & Schl.) Schum. The latter is a species of southern and central Brazil and Paraguay. Tocoyena neglecta diff'ers from T. formosa in the pointed elongated corolla-buds instead of ellipsoidal obtuse or rounded buds of T. formosa, in the acute or subacute instead of rounded corolla-lobes in anthesis, the moderately hirtellous calyx, the surface of which is visible between the hairs instead of densely velutinous and not visible as in T. formosa, and in the much longer and broader corolla-lobes. Much of the confusion between these two taxa is due to the similarity of pubescence on the lower surface of the leaf-blades, which is of a velvety tomentum with a reticulate tertiary venation, but the two taxa are amply distinct in the other characters given above.
