of appendages to the lateral divisions, whilst the inner divisions, opposite, 

 seemed lost or suppressed in the web edging the space occurring in the 

 mid-rib and dividing the sections of the blade, This webbed space is 

 10^ inches long. Beyond this the cjuinary modification again occurs in 

 the venation, producing an expansion of the blade that gives the palmate 

 character to this section of the leaf. Measurements were made of the 

 various parts, but are here omitted for the obvious reason stated before. 



At the 1st node a leaf of similar form and construction to the basic 

 leaves, was given off, but of less dimensions. 



At the 2nd node the first part of the leaf-stalk was represented by a 

 broad expansion of yellowish green and ribbed webbing that was rigid 

 and stem-like externally, clasping the stem below ; above, dividing into 

 three stalklets or petiolets supporting leaf-blades. Instead of the 

 cylindrical form of leaf-stalks below, these were prismatic. 



At the 3rd node a sort of extended stipula was formed, from the tip 

 of which extended short stalklets supporting much diminished leaves. 

 The central stalklet was IJ inch, the laterals f of an inch. 



Axillary groioths. 



A miniature leaf in the axil of one of the basic leaves has been 

 mentioned. In the axil of the first and second leafstalks an abortive or 

 sessile leaflet was observed, that in the second was hid in the stipular for- 

 mation. From the axil of the third there sprang the first umbel, the stalk 

 of which was 22 inches; at 13 inches from the base of the stalk, a foliated 

 stipular process divided into two parts, was found ; the foliated part appear- 

 ing on the upper edges, and representing a miniature leaf. In each part 

 a stalked flower-bud, complete in all details, in one instance enveloped in 

 a two-fold bract, and in the other a trifld bract, was revealed. At two 

 inches above this another stipiilar process appeared, enclosing in a bifid case 

 of the same colour a slightly stalked umbel-form. At the 4th Node appeared 

 a triple foliate stipule, each portion showing a different degree of leafiness 

 and size, but all in a much diminished degree compared with the stipule 

 at No. 3 node. From the axil of each of the three sprang the stalk of 

 an umbel. The stalk varied in length and thickness, in relative propor- 

 tion to the stipules. The three stipules were whorled one Avithin the 

 other. At distances on the three-flower stalks, varying from 11 inches 

 to 10§ inches, the peduncles themselves varying from I85 to 17^ inches ; 

 there were placed stipules enclosing sessile umbel buds which were 

 enveloped in secondary stipules ; the outer stipules had more or less 

 of leafiness at the tips, the inner ones weie very slightly so, and had 

 minute stalks. Two of these stipular bodies were bifid and one trifid, and 

 each division contained an umbel surrounded by secondary stipules. 

 These umbels, had they developed further, Avould have formed a third 

 series of blossoms. They were particularly interesting as analogues of 

 leaf-formation. 



The Inflorescence and Seed. 



The terminal umbel bloomed first, and the four lateral ones followed
