Your top picture is opposite of what I sent. Euphorbia lactea is the smaller piece and is harder. Has some sharp spines, although small. Stapelia Gigantea (Starfish Flower) is softer to the touch. It may take a year or so for it to get large enough to bloom. Also mine bloom in the late summer while they are outside. I have never noticed any smell but I never tried to get a whiff. I never saw any flies around it and I never got any seed pods from them. I am going to get a Stapelia Grandiflora this spring. It looks exactly alike only the flower is redder. Hetty knows more about them than me. I am new on these.
