Summary
‘Spot’ characters are features that occur in relatively few families, thus rendering their identification simpler than tracing them through the actual key. Note that the appearance of a family name under a particular character does not mean that all members of that family show the feature in question.

51 Rafflesiaceae, 157 Cynomoriaceae, 168a Monotropaceae, 206 Orobanchaceae, 239a Burmanniaceae.
Plants clearly parasitic on the above-ground parts of other plants, with chlorophyll (excluding hemi-parasites)
14 Santalaceae, 15 Loranthaceae, 15a Viscaceae, 36 Lauraceae, 189 Convolvulaceae, 192 Lennoaceae.
Plants with bulbs
