Common Names
Bulbophyllum lucifugum Summerh. is commonly known by its English common name - The Hidden Bulbophyllum, due to its growth habit and small size.
Description
Bulbophyllum lucifugum Summerh. is a mini-miniature orchid, with a multi-branched creeping rhizome from which several small pseudobulbs arise. The pseudobulbs are small, approximately 2cm in length, globose, and covered by sheaths. Each pseudobulb has a single leathery, ovate, dark green leaf that is approximately 3cm in length, and 2cm in width. The leaf and pseudobulbs are small and hard to see due to their cryptic nature.
Flowering occurs from Spring to Summer, with a terminal inflorescence that arises from the base of the young, newly grown pseudobulbs. The inflorescence bears a single flower that is approximately 3cm in width. The petals and sepals are yellow-green in color, while the lip is mostly purple-red. The lip is the most conspicuous part of the flower, with a complex structure, featuring fleshy lobes, papillae, and hairs, and a curved, pointed, and erect apex.

With these guidelines, you have the right information to grow Bulbophyllum lucifugum Summerh. successfully. Remember to keep your plant in conditions that mimic its natural habitat, water it adequately, fertilize it at the appropriate times, and prune it regularly.
Propagation of Bulbophyllum lucifugum Summerh.
Bulbophyllum lucifugum Summerh., commonly known as the Dark-Fearing Bulbophyllum, is a fascinating orchid species that belongs to the Bulbophyllum genus. It is native to the African tropics, where it thrives in warm, moist conditions. Propagation of the Bulbophyllum lucifugum Summerh. can be done through several methods, including seed germination, division, and tissue culture.
Seed Germination
Seed germination is the most common method of propagating the Bulbophyllum lucifugum Summerh. orchid. Fresh seeds are tiny, dust-like in size, and often come in seed pods that dry up and crack open in about two months after flowering. The seeds need to be extracted and sowed as soon as possible to ensure high viability. Sowing the seeds in a fine mixture of sphagnum moss and perlite or vermiculite provides a suitable medium for growth. The medium should be kept moist, and the seedlings should receive partial shade and high humidity until they are established.
Division
Division is another propagation method that can be used to produce new Bulbophyllum lucifugum Summerh. plants. This method involves separating the plant's pseudobulbs into smaller sections, with each section having one or two growing points, and then planting them in separate pots. This method is most effective during the plant's growth period, which is usually from spring to early summer. The divided sections should be placed in a suitable potting mix, provided with sufficient light, water, and nutrients to encourage quick growth.
Tissue Culture
Tissue culture is yet another method that can be used to produce multiple plants from the Bulbophyllum lucifugum Summerh. This method involves taking small pieces of the plant's cells or tissues, known as explants, and growing them in a sterile culture medium. In tissue culture, plant cells are grown in a test tube or flask that contains a nutrient-rich medium. The nutrient medium contains the necessary plant hormones to promote growth, while the sterile environment ensures that the explants are free from diseases and other contaminants. Tissue culture is a popular method for producing large numbers of Bulbophyllum lucifugum Summerh. plants in a short time.
Propagation of the Bulbophyllum lucifugum Summerh. orchid can be challenging, but with the right techniques, it can be done efficiently. Seed germination, division, and tissue culture are three possible options for producing new plants. Each method has its requirements and benefits, so it is essential to choose the appropriate method for your resources and preferences.
