Unless you know exactly what PHYSICAL CONTACT level the Author thinks that the plant might have, then it is best to leave the PHYSICAL CONTACT set to [Unspecified].

(PHYSICAL CONTACT level is mainly an informational parameter rather than one on which to base a search. If the Author doesn't know how hazardous the plant is to touch, he has left the PHYSICAL CONTACT blank, rather than put it at 'lowish'. i.e. The 'Lowish' rating is not the default setting for a plant that is presumed safe to touch). Indeed, the 'Lowish' rating is in fact the rating the Author has used for plants which present a laceration or puncture risk).

Alternatively, if you really would like to know which plants the Author thinks have a, for instance, severe PHYSICAL CONTACT rating, then click on contact?severe and a list will be produced.
