e 68 Benson. — ■ Telangium Scotti, a new Species of 
Is shown in one case in Fig. 9, which is from a slide kindly lent by Professor 
Weiss from the Collection of the Manchester Museum, Owens College. 
Thirdly, the character of the tissue. The tissue of the lower part 
of the synangium has much in common with the familiar sterile pinnae of 
Lyginodendron. We have a well-developed epidermis, a definite hypoderm, 
and lacunar tissue which is indistinguishable from the corresponding tissue 
of the sterile pinna. The vascular strand of the pedicel is composed of 
trachei'des of very narrow lumen, and thus resembles those of the petiole of 
Lyginodendron . The preservation of the tissue is unfortunately not good 
enough to show the form of the strand clearly. The group of trachei'des 
which is preserved (Fig. 4 c) may be the whole, but it is possible that 
another corresponding group may have occupied the other arm of a V- 
shaped strand, but has become opaque owing to the minuteness of the 
lumen of the tracheides. 
Fourthly, correspondence between the spores of Telangium Scotti 
and the pollen-grains germinating in the pollen-chamber of Lageno- 
stoma Lomaxi and ovoides. Ripe spores occur in five of the synangia 
already to hand, and have been measured by Prof. Oliver and myself. As 
already pointed out they agree with considerable exactness in form and in 
the character of the wall with the pollen-grains in the pollen-chamber of 
Lagenostoma, but the latter slightly exceed them in size. This comparison, 
already found of value in the magnificent work of Renault on Cordaianthus , 
is of great interest. The spores of Telangium average 5*5 [x in their 
longer and 37 /x in their shorter dimension. The spores when they 
are germinating, apparently in the very act of yielding antherozoids like 
those of Cycads and Ginkgo , measure 7 x 5 /x. The wall of both is thick 
and has thinner areolae, and thus may be described as reticulate, v. Fig. 6. 
Fifthly, correspondence of Telangium Scotti in certain morpho- 
logical characters with the seed Lagenostoma. The seed Lagenostoma 
(the three species of which were first named and partially described by 
Williamson) has since received a searching investigation at the hands 
of Prof. F. W. Oliver 1 . The connexion of one species, L. Lomaxi , with 
Lyginodendron has recently been announced 2 by him and Dr. Scott. To 
quote from their account of this species: f In the most general relations of 
its organization the seed approaches the Gymnosperm type in that the 
integument and nucellus are distinct from one another in the apical 
region only, whilst the body of the seed which contains the large single 
macrospore shows complete fusion of the integument and nucellar tissues. 
But in other respects the seed is remarkable. The integument, which 
is a simple shell where fused with the nucellus, becomes massive and com-
