Fasciation of th(.' stem in the Coiivolviilaccae has been several 

 times noted in the literature. I have seen it in Ipomoca fan- 

 durata and in the sweet potato, wiieie it ma\- almost be regarded 

 as a normal occurrence. 



Conard * has published detailed observations on the phenom- 

 enon. He attributes the first published notice to Macfarlane.t 

 apparentl}- not beini^ aware of the much earlier observation of 

 Fermond,;}; who describes a fasciation of one meter in length and 

 ten to twelve centimeters in width. 



Fine examples of fasciation were noticed in sprouts from the 

 stump of a tree of Mclia Azedaracli ten or fifteen feet in height 

 which had been winter-killed the preceding winter. Fasciation 

 has already been described for this s{)ecies. 



It is hardly necessar)- again to record branching of the spike 

 of Plantago lanccolata. 



Dudley § states that the spike of Planttigo Rugelii is frequently 

 fasciated at the tip and Gerard || records more or less branched 

 spikes. I have frequenth' noticed spikes which were fasciated or 

 in which the fasciation had extended to apical branching. 



Fasciation of the stem was noticed in a vigorous young plant 

 of Rhus typJdna. Penzig records fasciation in the twig of R. 

 glabra. 



The leaves of SUpJdiiin trifoliahiui are described as in whorls 

 of three or four. One bed of plants in the Missouri Botanical 

 Garden showed leaves arranged largely in whorls of five, those 

 of three and four being found much less frequently. Some of 

 the stems were markedly fasciated toward the tip. One stalk of 

 Silpldum intcgrifoluun with 3-whorled leaves was found at Mera- 

 mec Highlands. 



Fasciation in the stem is again noticed in Spinacia olcracca. 

 Marked fasciation of the stem o{ StcpluDiotis fioribuiida was noted 

 for me by Mr. G. E. McClure. Fasciation of the spike of \\r-
