Used a TGA image map with an alpha channel.  The code for the texture is:

#declare txt_uv_orange_flower=texture {
  pigment {image_map {tga "uv_orange_flower.tga" once interpolate 2}}
 finish {ambient 0.1 diffuse 1 phong 0}
 normal {bump_map {tga "uv_orange_flower.tga" once interpolate 2
bump_size -10}}
}

Just tried changing the image type to PNG with an alpha channel (saved from
Paint Shop Pro v7.04 if you're interested), but still no better.

Ho hum.
