János Hulják prominent Hungarian botanist was born 130 years ago. He worked as teacher and director in elementary school at Pereces (today it belong to Miskolc). He played key role in the floristic exploration of Northern Hungarian Mountain Range. His huge herbarium collection was destroyed during World War II., only the exchange material was preserved (about few hundred sheets), mainly in BP and DE. Some vascular plant species [Centaurea huljakii J. Wágner, Sorbus huljakii Kárpáti, Galium × huljakii Jávorka and Pilosella auriculoides subsp. huljakii (Zahn) Soják] were named after him.

Hulják János a Miskolc melletti Perecesen dolgozott tanítóként. Munkássága során elévülhetetlen érdemeket szerzett az Északi-középhegység florisztikai feltárásában. Nevéhez fűződik többek közt a Lathyrus pisiformis és a Micromeria thymifolia kimutatása hazánk területéről.
