The genus Artocarpus J.R. Forster & G. Forster shows a higher diversity along the tropics of Indo Malayan region to Australasia. The Artocarpus phylogeny is resolved in previous studies. According to morpho-genetic assessments, Artocarpus spp. have been subdivided into subgenera and sections. However, the published phylogenies did not comprise the Artocarpus spp. found in Sri Lanka, leaving an ambiguity of their phylogenetic positions. The morphology was observed in many trees in natural range, and the line diagrams were drawn to showcase the morphological features that can be used to classify the Artocarpus spp. into subgenera and sections. We collected leaf samples from the Artocarpus spp. in Sri Lanka. The genomic DNA was extracted, and PCR amplified for five markers (trnH-psbA, rbcL, trnL-F spacer, trnS^GCU-trnG^UUC, and ITS1-4) followed by sequencing. The Artocarpus phylogeny was constructed in Maximum Likelihood and Bayesian framework using the generated sequences and the related sequence-popsets. Moreover, a divergence dating analysis was also carried out to check the evolutionary history of Sri Lankan Artocarpus spp. According to the morphology and phylogeny, the subgeneric classification of A. heterophyllus Lam, A. altilis (Parkinson) Fosberg, and, A. camansi Blanco was in line with previous studies. The dating analysis revealed a recent introduction of A. heterophyllus, A. altilis, and, A. camansi into Sri Lanka because of the associated food values. We positioned A. nobilis Thwaites, an endemic species to Sri Lanka, in the Artocarpus phylogeny under section Duricarpus. The nomenclatural status of A. gomezianus Wall. Ex Trécul coming under subspecies zeylanicus was verified as it does not clade closely with true A. gomezianus. However, we kept the species name as A. gomezianus as both true A. gomezianus, and Sri Lankan species got 10–13 pairs of lateral veins and the whitish hair underneath the leaf. We also recognized three ancient lineages of subgenera Artocarpus and Pseudojaca. These species naturally occur in India and Sri Lanka where they might be close descendants of the common ancestors of the subgenera Artocarpus and Pseudojaca.

属桂JR福斯特＆G.福斯特示出了沿印马来亚区域的热带到大洋洲更高的多样性。在桂发展史在之前的研究解决。根据形态-遗传学评估，面包果属。已细分为子类和部分。但是，已发表的系统发育不包括面包果。在斯里兰卡发现，其系统发育位置不明确。在自然范围内的许多树木中观察到形态，并绘制了线图以展示可用于对面包果树进行分类的形态特征。分为子属和科。我们从面包果中收集了叶子样本spp。在斯里兰卡。基因组DNA提取，PCR扩增5个标记（trnH序列-的psbA，rbcL基因，trnL - ˚F间隔，TRNS ^GCU - TRNG ^UUC，和ITS1 - 4），然后通过测序。的红桂系统发育中使用所生成的序列和相关序列popsets在最大似然和贝叶斯框架构成。此外，还进行了发散定年分析，以检查斯里兰卡面包果的进化史。根据形态和系统发育，亚种的分类A. heterophyllus林，A. altilis（帕金森）Fosberg，并A. camansi布兰科是与以前的研究一致。约会的分析表明，近期出台A. heterophyllus，A. altilis，并A. camansi因为相关食品的值到斯里兰卡。我们定位A.扇贝香棒，特有植物斯里兰卡，在红桂下部分系统发育Duricarpus。A. gomezianus Wall的命名状态。经过验证的ExTrécul属于亚种zeylanicus，因为它不能与真正的A. gomezianus紧密结合。但是，我们将种名命名为A. gomezianus才是真正的A. gomezianus，而斯里兰卡的种有10–13对侧脉和叶下面的发白。我们还认识到了面包果亚科和假单胞菌的三个古老世系。这些物种中天然存在于印度和斯里兰卡，他们可能是亚属的共同祖先的后代密切桂和Pseudojaca。
