    Here's an interesting bit of trivia regarding Rafflesiaceae - they've recently been shown to be a clade in the Euphorbiaceae. (This probably doesn't mean jack to most of you, but swords and I both collect Euphorbs.)
    I just looked to see if those results also applied to Hydnora, because I thought it was related to Rafflesia, but it's not. I was surprised to find that it's in the Piperales, along with ginger and Indian pepper - apparently Aristolochia is the most closely related sibling genus.

    According to Rafflesia of the World they are/were classed in the same super-order I shall paraphrase page 4:

    "In terms of taxonomic position Takhtajan placed the super-order Rafflesianae (containing Rafflesiaceae and Hydnoraceae) between the sub-classes Magnoliidae and Ranunculidae. ...(description of years of botanical mischief up and down the order ladder)... Thorne places the super-order Rafflesiliflorae near the more primitive dicotyledons in the super-order Annoniflorae, which includes the Order Annonales and the family Aristolochiaceae."

    And again they are paired up in a list of parasitic plant families on page 6:
    entry # 3. Rafflesiaceae & Hydnoraceae

    Unfortunately that's the last mention of Hydnora in the book. Perhaps they aren't as related as they appear to me in this text.

    Bad book, I shall make it sit in the corner!

    Everything is explainable. The seemingly unexplainable is but a result of our insufficient knowledge.- Hans Brewer
