answer: no
context: Title: Brian Mathew
  Passage: Brian Frederick Mathew MBE, VMH is a British botanist, born in the village of Limpsfield, Surrey, England.  His particular area of expertise is bulbous plants, particularly ornamental bulbous plants, although he has contributed to other fields of taxonomy and horticulture.  He has authored or co-authored many books on bulbs and bulbous genera which appeal to both botanists and gardeners, as well as specialist monographs on other genera, including "Daphne" (with Chris Brickell), "Lewisia", and "Helleborus".  His work has been recognized by the British Royal Horticultural Society and the International Bulb Society.
  Title: Ledebouria socialis
  Passage: Ledebouria socialis, the silver squill or wood hyacinth, is a geophytic species of bulbous perennial plant native to the Eastern Cape Province of South Africa.  It was first described by John Gilbert Baker as "Scilla socialis" in 1870.  John Peter Jessop later revised the genus "Scilla" and split off several species, reclassifying "Scilla socialis" into the genus "Ledebouria" in 1970.  It is often cultivated and grows well with minimal care.
  Title: Muscari neglectum
  Passage: Muscari neglectum is a perennial bulbous plant, one of a number of species and genera known as grape hyacinth and in particular common grape hyacinth or starch grape hyacinth. " Muscari" are perennial bulbous plants native to Eurasia.  They produce spikes of dense, commonly blue, urn-shaped flowers.  It is sometimes grown as an ornamental plant, for example, in temperate climates as a spring bulb.
  Title: Bulb
  Passage: In botany, a bulb is structurally a short stem with fleshy leaves or leaf bases that function as food storage organs during dormancy.  (In gardening, plants with other kinds of storage organ are also called "ornamental bulbous plants" or just "bulbs".)
  Title: List of Award of Garden Merit tulips
  Passage: The following is a list of tulip species and cultivars which have gained the Royal Horticultural Society's Award of Garden Merit.  They are bulbous perennials, originally from sunny, open habitats in Europe and Asia.  Thousands of cultivars are available in a huge range of sizes, shapes and colours (other than pure blue).  They are usually sold as bulbs to be planted in autumn and winter for flowering in mid- to late spring.  They are frequently treated as bedding plants, accompanied by other seasonal favourites such as wallflowers and forget-me-nots, flowering for one season before being discarded.  However, in favoured locations they can be left in the ground to re-appear the following and subsequent years.  Like many other bulbous plants they require a hot, dry dormant period in the summer.
  Title: Drimiopsis
  Passage: Drimiopsis is a genus of African bulbous perennial herbs in the family Asparagaceae, subfamily Scilloideae, native to sub-Saharan Africa.  Sometimes species are placed under the genus "Ledebouria".
  Title: Ledebouria
  Passage: Ledebouria is a genus of African bulbous perennial herbs in the Asparagus family, Asparagaceae, subfamily Scilloideae.  Most members were previously part of the genus "Scilla".  A number of species are grown by cacti and succulent enthusiasts for their patterned leaves.
  Title: Muscari
  Passage: Muscari is a genus of perennial bulbous plants native to Eurasia that produce spikes of dense, most commonly blue, urn-shaped flowers resembling bunches of grapes in the spring.  The common name for the genus is grape hyacinth (a name which is also used for the related genera "Leopoldia" and "Pseudomuscari", which were formerly included in "Muscari"), but they should not be confused with hyacinths.  A number of species of "Muscari" are used as ornamental garden plants.
  Title: Psychopsis
  Passage: Psychopsis, abbreviated Psychp in horticultural trade, is a genus of 5 known species of orchids native to northern South America, Central America and Trinidad.  It was formerly included in the massively paraphyletic "wastebin genus" "Oncidium".
