Two flowers had contracted an adhesion by the outer surface 

 of one lobe of the perianth of each : the flowers were both com- 

 plete. A slender scape, bearing a simple, terminal flower, sprung 

 from the plant bearing the above.

Noting a tendency in this variety of the potato to form sub- 

 terranean branches and tubers without throwing up aerial stems. 

 This anomaly usually occurs in winter, and M. Decaisne attri- 

 butes it to defective warmth and hght.

The entire inflorescence was transformed into successively 

 super-imposed whorls of sepals and carpellary leaves. Towards 

 the summit of the stem were four or five concentric circles of free 

 oval-lanceolate sepals — apparently resulting from the superior 

 and lateral sepals of several flowers. Immediately within these, 

 without the interposition of petals or stamens, were numerous 

 distiuct carpels, mostly of normal structure, and enclosing ovules. 

 The interior were iisually more or less open, and passing into 

 simple leaves. Upon the margin of the open carpels were imper- 

 fectly developed ovules. Above the carpellary whorl was a second 

 series of leaflets, less coloured and petaloid than the lowermost ; 

 then a second circle of carpels, most of which were imperfect. 

 Above these, and terminating the axis, was a compact mass of 

 small linear greenish leaflets.
