[Botany • 2016] Strobilanthes agasthyamalana • An Enigmatic New Species (Acanthaceae) from Agasthyamala Biosphere Reserve of Southern Western Ghats, India  | Strobilanthes agasthyamalana Sasidh., Dantas & Robi
|
Summary Strobilanthes agasthyamalana is described and illustrated here from the Pongalapara region of Agasthyamala Biosphere Reserve, southern Western Ghats. It is similar to S. foliosa and S. lanata in floral, seed and vegetative characters. However, it differs from S. foliosa by its adaxially hirsute and abaxially woolly leaves, bracts and bracteoles, pubescent corolla and villous style, and it differs from S. lanata by its glabrous stem, adaxially hirsute leaves, pubescent corolla, villous style and glabrous seeds.
Key Words: Kerala; kurinji; Strobilanthinae

[Botany • 2014] Gracilaria lantaensis • A New Flat Gracilaria (Gracilariales, Rhodophyta) from the Andaman Coast of Thailand
 | Gracilaria lantaensis

Collection of a flat red alga of the genus Gracilaria from the Andaman coast of Thailand was described as a new species, Gracilaria lantaensis sp. nov. based on detailed morphological characteristics and rbcL sequence analysis. This species typically grew intertidally on exposed mud-sand shores. It was characterized by its slender thalli with narrow-bladed branches, its smooth margin with a few brachlets and its reddish-pink color. Spermatangial conceptacles were of the textorii-type. Cystocarps were spherical and possessed numerous nutritive filaments at lateral and basal positions in the cystocarp cavity. Gracilaria lantaensis was morphologically similar to G. yamamotoi but differed in branching pattern and cystocarp structure. RbcL sequence data also indicated the genetic distinction between G. lantaensis and other species of Gracilaria. Gracilaria lantaensis was grouped with a major assemblage of Gracilaria species, and sister to some Indian Ocean species with denticulate margins, e.g. G. beckeri, G. capensis and G. denticulata.
Key Words: Gracilaria lantaensis sp. nov, Gracilariales, Indian Ocean, rbcL, Rhodophyta, Thailand
DIAGNOSIS: thalli solitary, flattened and erect, 2–11 cm long and 1–6 mm wide, arising from discoid hold fast with a stipe, 2–10 mm long.Blades had smooth margins with few branchlets, irregularly di- ortrichotomous branched and 250–450lm thick. Spermatangial conceptacles were scattered throughout the blade, forming shallow pits,textorii-type. Mature cystocarps were spherical, slightly rostrate and constricted at their base. Nutritive filaments mostly lateral andbasal, connecting to a thick pericarp. Carposporangia in unbranched chains. Tetrasporangia cruciately divided and scattered over the blade.

TYPE LOCALITY: 7838054.1100N, 9981014.5100E; attached to pebbles or shells on the muddy sand area in the intertidal, 1–2 m deep, at Ao Kaw Kwang, Lanta Island, Krabi Province, Thailand (Fig. S1). ETYMOLOGY: lantaensis refers to the locality of Lanta Island where this species is found. Narongrit Muangmai, Giuseppe C. Zuccarello, Thidarat Noiraksa and Khanjanapaj Lewmanomont. 2014.
