brown on the side most exposed to light, in the two lower internodes. 

 Thirty ridges were counted around the base, and 23 in the upper three 

 internodes, tliey gradually became finer above and the grooves between 

 them narrower ;ind shallower. From the position of the plant the stem 

 early actpiired an obli(iuc direction towards the open spare where there 

 was more light, it also formed a long upward curve in the lower part. 

 By the weight of the advancing growth and formation of the inflorescence, 

 the deflection became greater, so that a person of moderate height could 

 reach the terminal umbel that should have been placed 9 feet from the 

 surface. 



Leaves. 



There were two apparently opposite base leaves, the others being set, 

 alternately, on the stem. They were all large and coarse with a wide 

 expanse of the blade, which was deeply cut into segments, assuming a 

 pinnate form, being irregularly serrate on the margin. The lower leaves 

 wcK pctiolate, the stalk grasping the stem by amplexicaul dilation that 

 extended round the node in a partial and an obli(jue sheath In the 

 U])pi'r leaves the blade sprang from this expanded portion, which had a 

 tendency in some instances to become more stipulate and foliaceous. The 

 h'af stalk divided in three lesser ones or petioles, a central and two 

 latcial ones, from which the blades expanded. The main nerves of the 

 bhide had the same tendency to triple division, producing opposite lobes 

 iin either side of the expansion ; the next division was alternate and then 

 the nerves became reticulate. The leaves were dark green above, light 

 green beneath. The central division of the blade, both in the primary 

 and sub-divisions, was the largest, and less pointed in form. The 

 divisions of the blade in the larger leaves were marked by a space along 

 tlie mid-rib which was winged on either side. The further observations 

 on particular leaves have been condensed to save space. The two base 

 /raves, though apparently arising from the same level, were not exactly 

 onposite. The measurements varied considerably ; this was partly due to 

 injury and obstructed growth in one uf them. Arising out of the axil of 

 the one which might be considered the lowest, appeared an attenuated 

 small and more pointed leaf. By the triple sub-division of the leaf-stalk 

 these basic leaves presented three separate sections, right, left, aud central, 

 all formed upon the same plan of venation with certain modifications 

 adapted to the position and size or importance of the part. The central 

 form-d the largest aud most important section. The n'^ht and hit 

 sections were similarly constructed. In the outer sub-division of each 

 suction it was noticeable that a subsidiary lobe was formed and a moilifica- 

 lion of the venation occurred to produce it ; the ternary division assumed 

 a quinary one, by two of its secondary veins approximating the sizes of 

 the primary, and passing obliquely backwards from their origin. The 

 central section Avas more expanded, taking a somewhat palmate form ; the 

 segmentation, indentation, and division of the parts, were more pronounced. 

 I'lie quinary ramification, already alludetl to, was more marked and 

 decided, and produced two lobes so reversed as to assume the appearance
