Orange up with Begonia cumingii

-

Most Begonia flowers are white. Or white and red at the back. Or pink. In fact, no matter how pretty the flowers may be, we don't really pay attention to these that much because the flower color is pretty uniform in many species. Not so with Begonia cumingii, a species with large, bright orange flowers.


Begonia cumingii is a Philippine endemic, and is found only in a few provinces on Luzon. I have seen this species in the provinces of Laguna and Quezon, which are adjacent to one another. These plants are often found in very wet areas close to running bodies of water, mostly at medium altitudes. The species was named after Hugh Cuming, who collected the first plants known to science in 1811, but without precise locality. However, since he collected extensively in the province of Laguna, it is possible that the type specimen was found from somewhere there, possibly either in the town of Calauan or Majayjay.

Pistillate flowers of B. cumingii.
This is quite a large, shrubby species, and the tallest I have found is around 1.5 m tall, growing in deep shade. However, in brighter light, the plants become more compact with a rounded form. In common with many begonias, B. cumingii is almost always in flower, and plants are easy to detect even from some distance away due to the flower color.

Begonia cumingii is from section Petermannia, with erect and branching stems. Not to be outdone by the flowers, the glossy leaves have serrated margins and prominently veined. The venation on the leaf undersides is dark red. Not at all boring!


This species is sparingly present in private collections, but is not easy to keep due to their ecological requirements. I even doubt if it is present in collections abroad. Although there is the likelihood that as soon as I say this, someone will show me a photo of a B. cumingii from outside the Philippines 😅

The tallest specimen I ever found of this species. It's even taller than I am- but only because it was growing on a rock.

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

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
