Question: Can both Pieris and Lechenaultia plants have leaves? 
Context: Pieris ( or ) is a genus of seven species of shrubs in the family Ericaceae, native to mountain regions of eastern and southern Asia, eastern North America and Cuba.  Known commonly in North America as andromedas or fetterbushes, they are broad-leaved evergreen shrubs growing to 1 - tall and 3 - wide.  The leaves are spirally arranged, often appearing to be in whorls at the end of each shoot with bare stretches of shoot below; they are lanceolate-ovate, 2 - long and 1.0 - broad, leathery textured, and with an entire or serrated margin.  The young leaves in spring are typically brightly coloured.  The flowers are bell-shaped, 5 - long, white or pink, and arranged in racemes 5 - long.  The fruit is a woody capsule which splits into five sections to release the numerous small seeds. Lechenaultia is a genus of plants in the Goodeniaceae family.  Some species of this genus are used like ornamental plants. "Lechenaultia" species are diverse in form: they may be woody or herbaceous, upright or prostrate with leaves flat, needle-like or virtually absent in mature plants.  The genus differs from other Goodeniaceae in the structure of the stigma and the fertilization mechanism.  They are found in Australia and New Guinea (one species). Krigia virginica, also known as dwarf dandelion or Virginia dwarf dandelion, is a North American species of plants in the aster family (Asteraceae).  This plant is a spring annual, consisting of a small rosette of leaves up to 6" across and one or more flowering stalks up to 14" tall.  Individual plants can bloom while they are a remarkably small size (only 2" across).  The basal leaves are up to 3" long and ¾" across.  They are light green, oblanceolate, and often pinnatifid with shallow lobes that are pointed at their tips.  Their margins are often ciliate, slightly undulate, and sparingly dentate.  Each flowering stalk is unbranched and devoid of leaves; it is largely hairless, although there may be a few scattered hairs along its length, especially near the top.  Both the basal leaves and flowering stalks contain a white latex. Phytophthora kernoviae is a plant pathogen that mainly infects European beech ("Fagus sylvatica") and "Rhododendron ponticum".  It was first identified in 2003 in Cornwall, UK when scientists were surveying for the presence of "Phytophthora ramorum".  This made it the third new "Phytophthora" species to be found in the UK in a decade.  It was named "Phytophthora kernoviae", after the ancient name for Cornwall, Kernow.  It causes large stem lesions on beech and necrosis of stems and leaves of "Rhododendron ponticum".  It is self-fertile.  It has also been isolated from "Quercus robur" and "Liriodendron tulipifera".  The original paper describing the species, stated it can infect "Magnolia" and "Camellia" species, "Pieris formosa", "Gevuina avellana", "Michelia doltsopa" and "Quercus ilex".  Since then many other plants have been identified as natural hosts of the pathogen.  Molecular analysis has revealed that an infection on "Pinus radiata", recorded in New Zealand in 1950, was caused by "P. kernoviae". Drought deciduous plants are those that drop their leaves during the dry season or periods of drought.  Examples include plants of the California coastal sage scrub community, and the leeward Hawaiian dry forest tree, the wiliwili ("Erythrina sandwicensis").  This may be contrasted to deciduous plants that drop their leaves during cold periods, or evergreen plants that have green leaves year-round. Pieris, the whites or garden whites, is a widespread now almost cosmopolitan genus of butterflies of the family Pieridae.  The highest species diversity is in the Palearctic.  Many species of this genus have caterpillars which feed on cabbage and other members of the Brassicaceae.  The chemical basis of this association with a certain plant group has been studied for over 100 years, and is now known to occur via a number of biochemical adaptations to chemicals called glucosinolates in these plants.  In contrast to most other insects, "Pieris" caterpillars are able to detoxify these chemicals, and have become so specialised that they will not eat any food without glucosinolates.  The "Pieris" females, in turn, check for the presence of glucosinolates before laying eggs on a plant.  The crop-damaging species have spread from Eurasia to most of the rest of the world (most recently to South America and Africa) and are considered pest insects almost everywhere.  There are species of "Pieris" that are not pests, such as the North American species "Pieris oleracea" and "Pieris virginiensis".  These butterflies feed successfully only on specific native vegetation. Pieris oleracea, the mustard white, is a butterfly in the Pieridae family.  Its historical range is in the Great Lakes area of the United States and southern Canada.  The caterpillars feed on brassica-type plants and the adults feed on flower nectar.  Some authors consider "P. oleracea" to be a subspecies of the green-veined white, "Pieris napi", of Eurasia.  Unlike "Pieris napi", however, "Pieris oleracea" cannot use garlic mustard, "Alliaria petiolata", as a host plant. Deinanthe is a genus consisting of a few species of rare herbaceous-habit rhizomatous plants found in the mountain woodlands of East Asia, ranging from China to Japan.  They are handsome clump-forming perennials good for shade, woodland and rock gardens.  These attractive deciduous plants have relatively large "fishtail" leaves (cleft at the apex).  Deinanthes grow at a slow rate to be bushy and shrub-like, 2ft tall and wide.  The leaves attain 3 to 4 inches in length,being deep green, roughly textured, deep veined, cordate at their bases and with serrate margins.  The shoots emerge from stout, knobby rhizomes.  Leaves are easily damaged in direct sun exposure.  Flowering occurs in late summer to early fall.  The delicate, waxy, nodding cup-shaped flowers in rich to pale purple-blue, rose or white, are borne in loose terminal clusters.  Resembling gargantuan fertile hydrangea flowers, with numerous yellowish to pale blue anthers, they are occasionally accompanied by sterile flowers, as in the lacecap hydrangeas.  Roots and leaves are edible. The term cabbage worm is primarily used for any of four kinds of lepidopteran whose larvae feed on cabbages and other cole crops.  Host plants include broccoli, cauliflower, Brussels sprouts, collards, kale, mustard greens, turnip greens, radishes, turnips, rutabagas and kohlrabi.  This small group of similar pest species is known to agriculturists as the cabbage worm compte butterflies (family Pieridae, type genus "Pieris", garden whites). The andromeda lace bug (Stephanitis takeyai) is a pest insect on plants of the genus "Pieris", especially "Pieris japonica", the Japanese andromeda.  It originated in Japan with its host plant but has since been introduced to other areas of the globe.  At least one "Pieris" species, "Pieris floribunda", is resistant to the bug.
