This article contains a list of the more than 2,200 vascular plant species of Doi Suthep–Pui National Park in Chiang Mai Province, northern Thailand from Maxwell & Elliott (2011:63-154).
Representative species by floral zone Doi Suthep–Pui National Park displays altitudinal zonation. This section lists some of the characteristic species of each floral zone.
Bamboo/deciduous seasonal forest Of the 173 tree species which occur in bamboo/deciduous forest, 125 (72%) are deciduous and 31 are common or abundant. Trees that are commercially valuable include:
Tectona grandis (heavily reduced by logging) Xylia xylocarpa var. kerrii Dalbergia cultrata Pterocarpus macrocarpus Lagerstroemia cochinchinensis Chukrasia tabularis Afzelia xylocarpa Other characteristic trees are:
Colona flagrocarpa Schleichera oleosa Terminalia chebula Terminalia mucronata Sterculia pexa Spondias pinnata Alstonia scholaris Protium serratum Adina trichotoma (especially near streams) Common understory trees include:
Vitex canescens Vitex limonifolia Cassia fistula Antidesma acidum Phyllanthus emblica Stereospermum neuranthum Characteristic deciduous understory treelets include:
Desmodium laxiflorum Desmodium pulchellum Woody climbers (lianas) are often quite large. There are 55 species, of which 65% are deciduous. They include:
Millettia cinerea Millettia extensa Combretum latifolium Congea tomentosa There are 30 shrub species, of which 63% are deciduous. Shrubs are represented by many species in bamboo/deciduous forest. Some typical examples are:
Helicteres elongata Helicteres hirsuta Desmodium gangeticum Desmodium velutinum Sericocalyx quadrifarius Phyllanthus sootepensis Sauropus hirsutus Bamboos include:
Bambusa membranacea Bambusa tulda Dendrocalamus nudus Bamboo/deciduous forest supports 38 species of epiphytes, most of which are perennial and 58% of which are evergreen. They mostly belong to 3 groups:
Moraceae (figs, many of which begin their lives as epiphytes) Orchidaceae (orchids) Pteridophyta (ferns) Species particularly characteristic of bamboo/deciduous forest include:
Ficus heterophylla, an evergreen woody climber Ficus microcarpa, an evergreen tree Cymbidium aloifolium, a succulent evergreen herb Platycerium wallichii Drynaria bonii Scurrula atropurpurea, an evergreen hemiparasitic epiphyte Epiliths include 12 species, usually restricted to rocks in streams. They include ferns such as:
Selaginella kurzii Pteris decrescens There are also several species of the family Gesneriaceae, include:
Chirita hamosa Streptocarpus orientalis The following herbs flower in April before their leaves appear:
gingers: Globba nuda Kaempferia rotunda orchids: Geodorum siamense Nervilia aragoana Nervilia plicata aroids: Amorphophallus macrorhizus Species appearing in May and June, at the start of the rainy season:
Curcuma parviflora Stemona burkillii Geodorum recurvum Habenaria thailandica Peristylus constrictus Plants that mature by July and August include ferns, etc. such as:
Selaginella ostenfeldii Anisocampium cumingianum Kuniwatsukia cuspidata Dryopteris cochleata (has bimorphic fronds; a characteristic fern) The grass most characteristic of the ground flora in bamboo/deciduous forest is:
Oryza meyeriana var. granulata Other common grasses, which also occur in other habitats and are highly combustible during the hot dry season, are:
Microstegium vagans Panicum notatum A total of 316 herb species has been recorded in bamboo/deciduous forest, of which 294 are ground herbs. Of those, 65% are perennial.
Deciduous dipterocarp-oak seasonal forest In seasonally dry or degraded areas, from the lowlands up to about 800-900 m elevation, deciduous dipterocarp-oak forest replaces bamboo/deciduous forest. It is a secondary, fire climax forest which merges with bamboo/deciduous forest, but is never replaced with mixed evergreen/deciduous forest. It contains less biodiversity with only 99 tree species, of which 24 are common or abundant. Dominant tree species of the Dipterocarpaceae include:
Dipterocarpus tuberculatus (especially common along ridge crests) Dipterocarpus obtusifolius (more common on gentle slopes or in slightly moister areas) Shorea obtusa Shorea siamensis Common Fagaceae species include:
Quercus kerrii Quercus aliena Quercus brandisiana Castanopsis argyrophylla (one of the very few evergreen tree species in deciduous dipterocarp-oak forest) Other characteristic trees are:
Phoenix loureiroi (a small, fire resistant palm) Ochna integerrima Additional common species:
Buchanania glabra Buchanania lanzan Craibiodendron stellatum Eugenia cumini Dalbergia cultrata Gluta usitata Symplocos racemosa Strychnos nux-vomica 2 tree species have rapid leaf turnover, flushing new leaves at the same time as the old leaves are shed. They include:
Tristaniopsis burmanica var. rufescens Anneslea fragrans The following tree is very common at higher elevations (650-800 m), along with the two trees listed above:
Aporosa villosa Deciduous dipterocarp-oak forest supports only 14 species of woody climbers, but the deciduous species that are easily found are:
Spatholobus parviflorus Aganosma marginata Celastrus paniculatus Shrubs (29 species) and treelets (48 species) are abundant. Some common examples are:
Helicteres isora Grewia abutilifolia Grewia lacei Desmodium motorium Desmodium triangulare Indigofera cassioides Gardenia obtusifolia Pavetta fruticosa Strobilanthes apricus var. pedunculatus Premna herbacea Premna nana Breynia fruticosa Breynia glauca Sauropus bicolor Sauropus quadrangularis Pueraria wallichii (a deciduous shrub; often scandent) Mussaenda parva (a deciduous vine, woody climber, or scandent shrub) Vines, often found in open, often burned, areas, are also common:
Dunbaria bella Solena amplexicaulis Streptocaulon juventas Argyreia henryi 47 of the recorded vascular plant species live as epiphytes. Some of the most characteristic are evergreen, succulent, vines and creepers in the Asclepiadaceae, such as:
Dischidia major (has two kinds of leaves, i.e. normal and bladder-like ones which have a symbiotic relationship with ants) Dischidia nummularia Hoya kerrii (less common than Hoya verticillata) There are numerous succulent, evergreen and deciduous Orchidaceae (orchids), such as:
