TKIASSIC! FLORA OF BALI) TITLL. 
()hservations- 'V}\Q present figui'ed specimen of the frond of 
IHIIophyll'um pecten in the Trias of Bacclms Marsh seems to bear 
out Nhnvell Arber's conchision that P. (watifolivm, wliicli tliat author 
lias floured from the Middle .lurassic of Southland, New Zealand,^*' 
is distinct from the present s])ecies. Tlie Bacchus Marsli specimens 
have the ])innae rather lono, slender, and acuminate towards the 
tip. Unlike those of P. acMijoliimi, they are rather crowded and 
])arallel-sided for quite two-thirds of their lenoth. 
Dimensions of fiyured spemmeii.- Vi \dt\i of frond, 28 mm. ; length 
of frond, as floured, 66 mm. Lenoth of lon,^est pinna, 2 mm. 
No evidence was obtained from the present series of specimens 
of the floral elements with microsporophylls. It may be noted, 
however, that occasional ovoid bodies like small nuts, enclosed in 
siliceous mudstone, when broken ojien, show a distinct cortex and 
within a mass of little seed-like bodies (see posted). 
Previously known from the Jurassic of Knofand,

Lower Cretaceous of Creenland.

Description. Several specimens of large, apfiarently ovoid or 
subcylindrical fruits, contah'ing small seed-like bodies, are found 
in tiie jiresent series. From their more or less distorted lorm, 
they must have been of soft texture when buried in the sediment. 
There ap|)ears to have been, a fairly thick, spongy cortex, within 
which are crowded innumerable spherical bodies. Jhese fruits 
remitid one of the ovulate strobils of the Cycadoidea. The enclosed 
seeds closely resemble the megasporo])hylls seen in the figure of 
Cijcadeoidea {Hot melt ites) Gibson iana figured by Seward.'*" They 
measure about 1 mm. in diameter and are sul)spherical or 
])olygonal. What a])pears to be a central vascidar strand is present, 
as also the thick cortex shown in Seward's figure. JJie strobil 
measures 23 X 30 mm. ^
