Final answer:
The archival collection does not explicitly mention who collected funds for flowers after Bruce's mother's passing, but typically such efforts are made by friends, family, or communities.
Step-by-step explanation:
The archival collection referenced in your question does not explicitly state who took up a collection for flowers following the death of Bruce's mother. However, it is typical in such circumstances for friends, family members, or communities to come together and contribute to such a collection as a gesture of sympathy and support. The provided information mentions cards of condolence and a draft letter thanking individuals for their kindness, which implies that there may have been a collective effort to provide such a token of remembrance. In literature, the act of bringing flowers to a grave, as mentioned in the archival collection, symbolizes respect and remembrance, a theme that can often be found in various narratives and character studies. Without the explicit mention of who organized the collection, one can only assume that it was likely one of these traditional groups.
