e the sinus terminating the dorsal suture is totally naked; it is this which should bear the stigma if Lindley's view were correct. 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 Violarieae. 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. Pedicelli apice articulat. Folii petiol. basi articulat. Stipulae minimae stipellae. In Jonesia, there are no petals. Humboldtia comes near Tamarindus, 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 connection 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. _Olacineae_. Certainly in habit, corolla, etc. Olacineae are allied to Aurantiaceae, but they are nearer akin to Santalaceae. The processes are indubitably modified stamina, with a great tendency to irregularity; 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 Santalaceae they approach in processes, valvate corolla, and placentation, also to Loranthaceae. 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
