Eriocaulon atop the aquarium

-
For the past years, species from the genus Eriocaulon have been finding their way in aquascaping circles as attractive foreground plants, albeit with very high light, CO2, and micronutrient requirements. In addition, constant water movement is a necessity and these plants display strong aversion to having algae growths on their leaves. For this reason, cultivation of Eriocaulon is preferably only done in high-tech aquaria.

Eriocaulon, depending on species, can be grown either immersed or emersed, that is, with the leaves above the water line but with their roots submerged in water. I don't think I am ready yet to meet its very specific requirements in my tanks, so I have opted to grow these plants above one of my aquaria, on an overhead filter so that the roots get constant water movement.

I believe this to be E. truncatum var. truncatum, by the way.

Plants and places: a list of places in the Philippines that were named after plants

-
Image
Many place names within the Philippines were taken from plants, historical figures, or from water features or references to it. However, the former appears to be much more widespread and perhaps reflect the early people's affinity with such plants, perhaps as sources of folk medicine, food, utilities, or simply as landmarks. Unfortunately, most of these place names no longer bear the plants so honored, and the meaning of such names have been largely lost to obscurity. Our so-called 'progress' has pulled us farther and farther away from nature: the nonstop road widening projects during the last five years have wreaked havoc on not a few roadside trees. A Facebook post shows the last and only known Acacia confusa - a Philippine endemic- along the Olongapo-Bugallon Road in the western Luzon province of Zambales that is slated for cutting. Some names are contentious, such as 'Balicbalic' and 'Vigan'. Still, many of these place names reflect a place's topogr...

Materials for an inorganic cactus and succulent mix

-
Image
Since I started my advocacy on using mineral mixes for cacti and other succulents, I have been getting swamped with inquiries regarding the types of rocks to be used, the ratio in relation with the other materials, and other nuances. In this post I will be getting more specific and discuss why some materials are not really suitable for use in this regard and why some ingredients are better than the others. But first let's talk about the pots. Pots Perhaps no other branch in horticulture has experimented with so many different kinds of containers than in the succulent sector. The often fantastic shapes of succulent plants lend themselves very well to such containers, many of which can be downright outrageous or even more beautiful than the plants they hold. Whichever container you use, it would be for the best interest of your plant if you choose one that is one or two steps larger than what you would normally consider for the size of the plant. I have said this before and...

Distinguishing Alocasia boyceana, A. heterophylla, and A. ramosii, and some words about asking for plant identification

-
Image
  In the Philippines, three commonly encountered Alocasia species are frequently mixed with one another that identification of plants posted in social media has resulted in a muddied concept of what constitutes what, with most plants getting labeled as ' Alocasia heterophylla ' even though practically no one can elucidate why he thinks it is that species. More on that later. Still, admit I should that I, too, was confused not too long ago until I got fed up with my own ignorance and decided to undo it once and for all. I now show thee the path to thy enlightenment. The main aim of this article is to allow you to reliably identify which is which. I am going to keep this ultra-simplified, so I am not going to talk about floral morphologies. People usually don't catch them in flower anyway and very few have the inclination to save dissected inflorescence samples in an alcohol solution for later reference. The other aim, well, we'll get to that later. Alocasia heterophylla...
