TAMARIND US, OLACINEiE, ETC. 



The true place of Moringa seems to be near Xanthophyllum with 

 which genus it has some remarkable points of resemblance, witness 

 the papilionaceous corolla ; unilocular stamina, their situation, ovary, 

 placentation, and lastly glandulation. 



To this Lindley has made an approximation by placing the order 

 near Violarieee. Its chief difference from Polygaleae, is habit, foliation, 

 and the perigynous insertion of corolla and stamina, and consequent 

 union of the sepals. As in Xanthophyllum there is no albumen. 



(An additional Xanthop. which until to-day I have always taken 

 for a Leguminosa. ) 



Tamarindus cal 4 partitus, sepals 2, superiorib. connatis. Pet. 3, 

 vexillo, sepalo postico composit ; opposit ; stamen tria ; sepalis 3, 

 inferior opposita. Stylus aestivation deflexus. PI. 3 — Fig. 4. 



Pedicelli apice articulat. Folii petiol. basi articulat. Stipulse mini- 

 ma? stipellse. 



In Jonesia, there are no petals. Humboldtia comes near Tamarin- 

 dus, through H. Brunonis, which agrees in calyx and petals. 



Thorns of Prionites, what are they ? They are axillary, and yet buds 

 are produced between them and the axis. They have no connec- 

 tion with the leaves. Were it not for the buds above alluded to, I 

 should say that they were abortive branches (bearing one pair of 

 leaves) reduced to spines. 



Olacinece. Certainly in habit, corolla, etc. Olacinese are allied to 

 Aurantiacese, but they are nearer akin to Santalacese. The processes 

 are indubitably modified stamina, with a great tendency to irregu- 

 larity ; in one species from Tagoung only three fertile, and five sterile 

 stamina were observed : the three fertile generally, but not invariably, 

 alternate with the petals. 



To Santalacese they approach in processes, valvate corolla, and 

 placentation, also to Loranthacese. 



Eight stamina thus accounted for ; when two opposed to petals, 

 belong to outer series — also single one. 



In Punica, the structure of the ovaria is highly curious. We find 

 the bottom of the tube is occupied by two cells, partially filled 

 with ovula, which are attached both to the axis and to the base, as 

 well as to the lower part of the outer paries of each cell; so far, 

 it does not depart from the order, for in Aplexus the placentation is 

 tolerably similar. 



Above these two, are 4-5 cells, filled with ovula, which are 



attached entirely to the outer wall of each cell, but the placentae
