And although there is already a great variety of officially recognized Hoya plants, a new subspecies was recently discovered by botanists from the Department of Science and Technology-Forest Products Research and Development Institute (DOST-FPRDI).

Hoya meliflua Merr. subsp. escobinae Kloppenb. Conda, Buot & Pitargue was added to the International Plant Names Index (IPNI) in 2016. It was discovered by DOST-FPRDI’s For. Jennifer M. Conda, Mr. Fernando C. Pitargue Jr., and Dr. Ramiro S. Escobin.

How the discovery came about

“Our team collected cuttings of the plant from the Quezon Protected Landscape in 2012. Immediately after the first flowers bloomed, we sent samples for examination to Dr. Dale Kloppenburg, a renowned Hoya expert from the United States.

“He then confirmed that it was a new subspecies, which showed several similarities with Hoya meliflua Blanco ex Merr. but with some notable differences. Results were published in Hoya New, a publication devoted to studies about Hoya, and listed in the IPNI,” she recalled.

According to her, the calyx lobes (sepals) of the new subspecies are tongue-like and long, as compared to the broadly oval to oblong of the Hoya meliflua Blanco ex Merr. Its corolla lobes (petals), meanwhile, are elongated and have serrated edge, in contrast to the latter’s broadly triangular lobes.

“Of the 109 Hoya species recorded in the country, 39 species and three subspecies are found in Quezon province. It is no wonder that another subspecies was uncovered in the same area,” explained Conda.

Hello, Cyber World! A journalist's passion for news, which for me is every and any kind of news, but specially on Science, Technology, Innovation, Digital, and Current News, or just about anything under Heaven, birthed this news platform. Disclosure: I am not a scientist nor an expert on anything Science, and not a techie either; just some journalist who loves and care to bring the good news and share them to everyone out there. It is a big, big physical world out there, but the Industrial Revolution 4.0, the Internet in the Digital Age, has shrunk Earth into one small virtual community. Each human being a "neighbor" to everyone in the Philippines and in any point of the compass. Whatever you may see or think could be my and this site's shortcoming, my apologies. So, there, please join me in my journey in cyberspace! Be home, be safe, be mindful of your neighbors, of the Creator! Thanks so much.
