their male and female cones are however extremely dissimilar. The Diselma always grows erect, from 5-U net 
high, with a stem sometimes 16 inches in diameter; the trunk exudes mm . small, tormina 
and oblong, hardly broader than the branchlet, with a few (six to eight) stamens, which have a very small, broad 
triangular, not ciliated, coriaceous termination to the connectivum, and two very largo, diverging e 
cones are small and ternainal, and consist of four scales in opposite pairs : the outer, smaller, M 
inner each bear two erect ovules at their bases. When fully formed, these tones are -till scarcely a line across: 
the scales are erect, and shorter than the seeds; these I have only seen unripe, they ..
