Crime Pays but Botany Doesn't

Original Article

Hacker News Discussion

📝 Discussion Summary (Click to expand)

1. Latin as the historic language of science

“Latin was used across the board in ‘traditional’ sciences in northern Europe at that time … his professional publications were in Latin.” — kriro

2. Modern plant‑identification tools and community apps

“I can strongly recommend the mobile app Flora Incognita… It’s made by a German university, free, no ads, and doesn’t collect personal data.” — iammjm

3. Guerrilla gardening & critique of conventional landscaping

“Add a water feature … it encourages variant microclimates which encourages biodiversity.” — contingencies (≈ “Slowly killing my lawn… Red bud trees will soon forest my property.” — razster)

These three threads capture the most common opinions in the discussion: the cultural‑linguistic debate over Latin taxonomy, the rise of open‑source plant ID apps, and the push for alternative, ecologically‑mindful landscaping practices.

🚀 Project Ideas

FloraOpen: Open‑Source Offline Plant Identifier

Summary

  • A privacy‑first mobile app that runs a lightweight ML model on‑device to identify plants from photos, with no tracking or account required.
  • Core value: delivers accurate, instant plant IDs while respecting user privacy and enabling contribution to open citizen‑science datasets.

Details

Key Value
Target Audience Hikers, gardeners, students, and citizen scientists who want a free, open‑source plant ID tool
Core Feature On‑device image classification using a TensorFlow Lite model; optional upload of observations to GBIF/iNaturalist with explicit consent
Tech Stack Kotlin/Android, Swift/iOS, TensorFlow Lite, Room DB, optional sync via Firebase (opt‑only)
Difficulty Medium
Monetization Hobby

Notes

  • HN users lamented that Flora Incognita and PlantNet are not open source and unavailable on F‑Droid (calmsolitude, rapnie) and praised privacy‑focused apps (iammjm).
  • An open‑source, offline identifier would satisfy the demand for a transparent, community‑driven botany tool and spark discussion about model training with crowd‑sourced data.

BotanicForensics: Collaborative Pollen & Plant Evidence Hub

Summary

  • A web platform for uploading, tagging, and analyzing pollen grains, seed fragments, or plant residues found at crime scenes or ecological surveys.
  • Core value: creates a searchable, crowdsourced reference library that aids forensic investigators, researchers, and guerrilla gardeners in plant‑based investigations.

Details

Key Value
Target Audience Forensic labs, law‑enforcement officers, ecology researchers, hobbyist investigators, and “criminal botany” enthusiasts
Core Feature Image upload with metadata (location, date, context), AI‑assisted pollen/grain classification, and community verification
Tech Stack React/TypeScript frontend, Node.js/Express backend, PostgreSQL + PostGIS for spatial queries, TensorFlow.js for client‑side inference
Difficulty High
Monetization Revenue-ready: subscription tiers for professional labs (e.g., $20/mo per seat)

Notes

  • Commenters highlighted the niche of “criminal botany” and forensic pollen analysis (HPsquared, chabska) and expressed interest in tools for analyzing plant evidence.
  • Such a hub would enable real‑world utility, foster interdisciplinary discussion, and could be extended to invasive‑species tracking or guerrilla‑gardening impact studies.

HerbariumPress: Digital Herbarium Builder & Tutorial Guide

Summary

  • An interactive app that guides users through the steps of pressing, drying, labeling, and storing plant specimens, while building a searchable digital herbarium.
  • Core value: turns a traditional herbarium‑pressing tutorial into a hands‑on learning experience with versioned specimen records and easy sharing.

Details

Key Value
Target Audience Educators, students, amateur botanists, and anyone interested in creating personal herbarium collections
Core Feature Step‑by‑step AR‑guided pressing tutorial, image capture with metadata (species, location, date), export to Darwin Core/ABCD format
Tech Stack Flutter cross‑platform, ML Kit for on‑device leaf‑shape hints, SQLite, optional web sync via Supabase
Difficulty Medium
Monetization Hobby

Notes

  • Multiple HN commenters requested a herbarium‑pressing tutorial (yreg, giov4) and wanted to see more herbarium photos.
  • By combining guided instruction with a digital collection tool, HerbariumPress addresses the learning gap and encourages community sharing of pressed specimens, prompting discussion on best practices and biodiversity documentation.
