The stems are green with few large green lenticels that occur in the top two thirds of the internode. The small number of lenticels means that the stems feel relatively smooth. Some dark green colouration may be seen above the lower node of the internode. The internodes are usually short and thick. The small number of green lenticels near the top of the internode is a key characteristic of this kava type. The short internode length distinguishes Yonolulu from Qila balavu.  Yonolulu was found to be cultivated on Kadavu, Viti Levu and Vanua Levu and Ovalau. Local names used to describe Yonolulu include: Mocikawa (on Kadavu), Karawa (on Kadavu and Viti Levu), Matanitabua (on Vanua Levu) and Leka (on Ovalau). 

The stems have very few lenticels, occurring mainly in the top third of each internode, and the stems exhibit some purple colour. Colouration in the internode varies between plants, from mainly green through to dark purple. Colour in the internode is darkest above the lower node and becoming lighter towards the top of each internode. Lenticels are purple and often with raised brown coloured centres. Internodes vary in length and are often short and thick but may be long. This kava type is distinguished by the relatively low number of dark or purple coloured lenticels on their internodes and the purple pigmentation in the stems. Damu is cultivated on Vanua Levu, Ovalau, Kadavu and Taveuni. Local names used to describe Damu include: Damu (on Vanua Levu, Taveuni, and Ovalau), Kasa Damu (on Vanua Levu), Yalu (on Taveuni), and Kasakasa Kula (on Kadavu). 

The stems are pale green with many small dark green lenticels spread over the length of each internode. The internodes are usually short and the stems are generally thick, with

pronounced nodes and a narrow “waist” in the internode. The large number of green lenticels is a key character of both Vula kasa leka and Vula kasa balavu. The short length of the internodes is the character that defines Vula kasa leka from Vula kasa balavu, and this distinction can be difficult to make.  Vula kasa leka has been observed being cultivated on Vanua levu, Viti levu, Ovalau and Kadavu. Local names used to describe Vula kasa leka include: Bisinisi (on Vanua levu), Vau leka (on Vanua levu), Diria (on Viti levu), Dokobana (on Ovalau) and Karawa (on Kadavu). 

Stems are green with many lenticels over the length of each internode. Lenticels are very dark green in colour, often with raised brown centres. Some dark green, verging towards

purple pigmentation may be seen just above the lower node of internodes. In some plants dark green triangular stripes may develop from the lower node and stretch up towards the upper node of the stem. These stripes may or may not be present and vary in size. Internodes tend to be long. These plants tend to grow above head height, and vary between a spreading and upright habit. Dokobana vula differs from Matakaro leka and Matakaro balavu in that the lenticels tend to be very dark green rather than purple, and that purple pigmentation, if present, is restricted to only a small part low on the internode. Dokobana vula tends to have long internodes like Matakaro balavu.  Dokobana vula has been seen cultivated on Vanua Levu, Kadavu and Ovalau. Local names used to describe Dokobana vula include: Dokobana vula (on Vanua Levu), Vula kasa leka (on Vanua Levu), Kasa naloto (on Vanua Levu), Gau (on Kadavu) and Matakaro (on Ovalau). 

The stems have many lenticels that are distributed evenly over the length of each internode. The lenticels are purple in colour, and the internodes have purple pigmentation which is darkest above the lower node and fades towards the upper node of the internode. The internodes are generally short. Petioles are generally dark red/purple in colour and the point on the leaf where the petiole joins the leaf has some purple colouration. A key characteristic of this kava type is that the purple pigmentation fades below the upper node of the internode so that an area of green stem can be seen below the upper node. The areas of green stem distinguish it from Loa kasa leka and Loa kasa balavu. Dokobana loa has been observed being cultivated on Viti Levu, Kadavu, Vanua Levu and Ovalau. Local names used to describe Dokobana loa include: Damu (on Viti Levu), Loa (on Kadavu and Ovalau), Loa kasa leka (on Vanua Levu), and Loa leka (on Vanua Levu).
