If you mean the font on the front cover, that's ITC Souvenir Demi (1970) [Daylight Fonts · Fonts In Use · Identifont]:

Natural history of the insects of India. 1842. Cover detail.

Hanahaki as an expression of grief.

“Grief, I’ve learned, is really just love. It’s all the love you want to give, but cannot. All that unspent love gathers up in the corners of your eyes, the lump in your throat, and in that hollow part of your chest. Grief is just love with no place to go.” ― Jamie Anderson

The loss of a loved one triggering debilitating bouts of Hanahaki because the love is no longer able to be reciprocal, because the person is gone.

Perhaps the societal ideal of flowers at a funeral is even tied to Hanahaki in a setting like this. Pulling the flowers of grief from your body to leave behind at the person's grave as an aspect of mourning and moving on.
