    Hechtia lyman-smithii is a species of plant in the genus Hechtia. This species is endemic to Mexico.

    Hechtia lyman-smithii - Wikipedia

    Hechtia is a small genus of bromeliad. While many other bromeliad genera have hundreds of species, Hechtia boasts only fifty. There are several unique features to the Hechtia genus that makes it stand out among other bromeliads. Many of these features make them excellent landscaping or outdoor container plants.

    HECHTIA: NATIVE REGIONS

    Most bromeliads are native to tropical regions. They originate from Florida to Brazil in moist, forested regions and are primarily native to Mexico. This home range gives Hechtia special adaptations that make them tough and allows them to handle conditions other bromeliads will not.

    Some of the Hechtia species can grow incredibly large. According to Bromeliad Society/Houston, Hectia melanocarpacan grow a rosette up to five feet across and produces a flower stalk that can reach eight feet tall. There are other species, such as Hechtia lyman-smithii that are much smaller. These small species grow only 5 or 6 inches wide, but often form large tight clumps.

    Hechtia will usually grow as large as the container they are planted in. When planted as a pup, these bromeliads grow quickly and should be repotted every year until they reach maturity. It can take up to three years or more for a plant to reach maturity.

    BLOOMING

    Most bromeliad species flower only once and then die. Hechtia can flower multiple times and continue growing and producing pups. They produce long flower stalks that grow out of the sides or center of the plant. Most Hechtia flowers are not very showy. They are generally planted for their interesting foliage. As the plants grow and mature, the tips of the leaves may begin to turn brown. This is not a sign of damage, but a normal occurrence. You can trim away the brown segments or leave them in tact. Neither technique will harm the plant. It is simply a matter of your preference in the appearance of the plant.

    Another unique fact about Hechtia flowers is that they can be identified as either male or female. Other genera of bromeliads have perfect flowers containing both male and female parts. Hechtia flowers are imperfect. They are always either male or female. This does not make much difference in the care or appearance of the flowers. However, if you want to propagate them from seed you must have one of each.

     

    Introducing Hechtia: A Bromeliad of a Different Variety (bromeliads.info)

    Hechtia lyman-smithii grows on steep calcareous hillsides where it forms large clumps or mounds of several to many rosettes. It is the only species in the genus that we have observed so far with this growth habit. Scape bract and inflorescence form appear similar in both pistillate and staminate individuals, but vary within a population. Lowermost scape bracts exceed the internodes and generally have elongate blades, but in some specimens blade length is much reduced. Upper scape bracts range from longer than to shorter than the internodes. Unlike some species we have observed and collected, both staminate and pistillate inflorescences of H. lyman-smlthii are bipinnate. Lateral branches are commonly fertile throughout, or are occasionally proximally without flowers. Primary bract length relative to the sterile bases of the branches is variable and is not a reliable character in H. lyman-smithii. Lateral branches in most pistillate specimens and one staminate specimen had two basal collateral flowers. In pistillate individuals of Utley & Utley 6982, branches occasionally did not develop, leaving only the two collateral flowers at each node. On these flowers and those of other inflorescences, floral bracts were typically borne some distance up the longer pedicel, rather than at the pedicel-branch junction as observed elsewhere in the inflorescence, suggesting that these flowers may represent the reduction of a lateral branch to a single flower. In staminate inflorescences of both Utley & Utley 6794 and 6982, unusual flowers with four sepals and petals and eight stamens were intermixed with normal flowers consisting of three sepals and petals and six stamens. In the absence of pistillate material at anthesis, it is impossible to unequivocally determine whether pistillate flowers also have additional perianth parts; however, all capsules examined were trilocular. These atypical staminate flowers observed on H. lyman-smlthii are not only unusual in Hechtia, but also in the Bromeliaceae as a whole. Perfect or staminate flowers in the family are characterized as having three sepals, three petals, and six stamens (Mez, 1934-1935; Smith & Downs, 1974; Cronquist, 1981)
