32G BENTHAM ON MIMOSE^. 



It may possibly be the rudiment of a terminal pinna or leaf- 

 let ; but as there is no evidence beyond its position, to show 

 that it is so, I have been unwilling to give it any other name 

 than seta terminalis, 



4. Between the pinnse of each pair, in some species of 

 Mimosa, there is on the common petiole, a tubercle or seta 

 often similar to the seta terminalis of the same leaf, occa- 

 sionally longer and even thornlike. This also has sometimes 

 been described as a gland, at others as a prickle ; but is 

 always very diflferent in appearance, as well from the petiolar 

 glands, as from the other prickles of the petiole. The regu- 

 larity of insertion of these organs, when they appear, gives 

 them some importance ; yet, as there is nothing to show their 

 real nature, I have not noticed them by any special name, 

 but called them setcG or tuberculii according to their appear- 

 ance. 



5. Near the base of the partial petioles of many species, 

 especially of the genus 3fi)nosa, are a pair of small setiform 

 or foliaceous appendages, to which, from their situation, I have 

 applied the name of stipellcey as being in many respects 

 analogous to the stipellm of the Cccsalpinieai. These also 

 are sometimes described, as glands. 



A strange mistake has occurred (as has I believe been 

 already pointed out by Endlicher), in giving the name of 

 repliim to the thickened sutural margins of the pod of Mimo- 

 sa, Entada, and Schranckia, which persist after the remain- 

 der of the valves have detached themselves and fallen out. 

 The word is found in Vitruvius, and was thus applied by 

 botanists on the supposition that that writer meant by it the 

 architrave or frame of a door ; but it has been shown that it 

 was rather the leaf of the door that was so called. At any 

 rate, it appears to me that the term is unnecessary, the word 

 marrfo, of which the meaning is clear, answering the purpose 

 perfectly well.
