Morphological Notes. S. B. Parish (Erythea, i, 45-47; E. L. 
Greene, |. c. 52). 
Description of lateral flowering in Agave Americana, and re- 
marks on the nature of the petiolar glands in Armeniaca vulgaris, 
which, it is suggested, represent the petiolules of reduced leaflets. 
Nematophycus Storriei, nov. sp. C. A. Barber (Ann. Bot. vi.. 329- 
338, Pl. XIX. XX). 
The plant originally described by Dawson as Prototaxites, from 
the Devonian rocks of Canada, and afterwards studied and re- 
named by Carruthers as Mematophycus, on account of its evident 
algal affinities, were made the subject of close microscopic exami- 
nation by the author, in connection with specimens of Pachytheca. 
Asa matter of interest it may be here noted that these genera, 
and Chara, are almost the only fossil algze in which well defined 
structure is apparent, and the first two were long suspected to be 
merely parts of the same plants. The specimens of Wematophycus 
upon which the new species is founded, were obtained from the 
Tymawr quarry at Cardiff, Wales, in rocks ofthe Wenlock (Upper 
Silurian)* age, associated with remains previously indentified as 
Pachytheca. 
In addition to the full description of the new species a descrip- 
tion is given, for the purposes of comparison, of V. Logani (Daw.) 
Carruthers, and in the plates both species are made the subjects of 
numerous studies in longitudinal and transverse sections.

This is a large work designed to encourage the growing of de- 
sirable plants adapted to the northern conditions. Full lists,in the 
notes for each sort, are given for deciduous trees, evergreen trees, 
shrubs, vines and climbing plants, herbaceous plants followed by 
tables of hardiness.
