 be the result of identical responses to the same stimuli"
 (1973:153). Careful study of glosses of Tzeltal plant names in
 Berlin et al. (1974), however, shows this not to be entirely the
 case. Example #88 from Table 4 (Berlin et al. 1973:159), ifil?ak
 in Tzeltal, is glossed as 'itchy vine' in Berlin et al. (1974:374).
 They stated "The sap derived from the leaves is a well-known
 skin irritant, hence the plant's name" (Berlin et al 1974:374). As
 such, the similarity between Tzeltal and Tzotzil names for this
 species could be a result of "identical responses to the same
 stimuli" and, by this criterion, should have been excluded from
 comparison. Other examples include #29, V'is te (Berlin et al.
 1973:156), a thorny plant elsewhere glossed as 'spine tree' (Berlin
 et al. 1974:191) and #41, tus?'ak, the word for wild onion,
 elsewhere glossed as 'stink grass' (Berlin et al. 1974:458). In fact,
 our analysis explicitly includes such names, as long as the
 referents are of neotropical origin.
