While flowering would indeed confirm the species, I must admit that it's highly unlikely for any of the suggested plants to bloom in an aquarium setting. Aponogeton crispus is one of the more likely candidates to flower, but given the current leaf growth, I'm inclined to rule it out. The plant's appearance doesn't match Barterraca either.boomer wrote: ↑Fri Feb 21, 2025 11:37 pm The first photo appears to be an Echinodorus species, commonly known as Burhead or Amazon Swords. Given the leaf veins, rosette form, and what seems to be a rhizome in the substrate, it shares characteristics with Echinodorus. However, I must note that the taxonomy of this genus is often confusing, with numerous artificially cultivated varieties stemming from naturally occurring species that were likely misclassified to begin with. I recall having a similar plant that initially had leaves almost flat on the substrate, but it has since grown more vertically; unfortunately, I've lost track of the tag name.
As for the second plant, which seems to be the mass of runners on the wood branch, I'm not quite sure what it is. I've had little success with carpeting plants, which this might be, or something similar.
Echinodorus species flowering in a permanently submerged aquarium is extremely rare. My personal experience with E. griesbachii ("bleherae" form) has yielded multiple inflorescences, but no actual flowers. On the other hand, my E. major has flowered twice in seven years, which is a unique case, as this species is naturally permanently submerged and never emersed. Other Echinodorus species, being bog or marsh plants, adapt well to submerged cultivation but rarely flower. Notably, adventitious plants have developed after flowering, contradicting Rataj's (2004) claims.
