Upon a very Rare and Special Ramification of Yucca 

 Aloifolia L. By ANTONIO PRESTANDREA, of Messina. 

 Messina, 1845, p. 8. Such ramifications are by no 

 means rare, especially in warm climates. I have fre- 

 quently observed the ramification of the scape of Agave 

 Americana below the inflorescence, in Messina. 



A Monstrosity of Primula Sinensis, in which a cup- 

 shaped body upon which the naked placenta was situated, 

 occurred upon the style, is very remarkable. Babington, 

 Ann. of Nat. Hist., xiii, p. 464. Dr. Dickie describes 

 several monstrosities in Gentiana campestris, ibid, xv, 87. 



Monstrosities in Digitalis purpurea through several 

 generations, observed by Vrolik. Flora, 1844, i. 



Professor von Schlechtendal's Remarks upon a Mon- 

 strosity of the Capsule of Papaver Somniferum, are also 

 extremely interesting. Bot. Zeit., 1845, p. 6.
